Description

Information carrier precursor and its preparation method, information carrier and its manufacturing method

field of invention

The invention relates to an information carrier precursor, a method for producing an information carrier precursor, a method for producing an information carrier and an information carrier produced therewith. the

Background of the invention

The field of security covers not only personal documents such as passports, driver's licenses, identification cards (ID cards) and permit documents such as visas and tickets, but also the authentication and identification of products to avoid counterfeiting, tampering and fraud such as lottery tickets, stocks, transaction documents, luggage and Labeling on pharmaceutical packaging and often high-value products. the

The term "identification card" covers cards that require identification of the bearer and ranges from national identity cards to establish a country's identification with its citizens, to cards involved in the electronic transfer of money, such as bank cards, payment cards, credit cards and shopping cards , to secure cards that allow the cardholder to enter specific areas, such as into companies (employee cards), the military, public facilities, vault departments of banks, etc., to social security cards, to membership cards for clubs and societies . the

Typically, an ID card contains information relating on the one hand to the institution that issued the card and on the other hand to the owner of the card. The first type of information may be general information, such as the name and/or logo of the issuing authority, or security markings, such as watermarks and security printing, such as repeating monochrome patterns or gradient color patterns that are difficult to counterfeit. The second type includes, for example, a unique card number, personal data such as date of birth, photo and signature of the owner. The card may further contain hidden information and thus a magnetic strip or an electronic chip ("smart card"). the

A large set of ID cards is usually prepared on a large web or sheet by a step-and-repeat process, which is then cut into appropriately sized objects, each object representing an individual ID card. Smart cards and ID cards now have standardized dimensions of 85.6 mm x 54.0 mm x 0.76 mm. the

Normally the card is protected by a plastic sheet material, for example by laminating the card to the plastic sheet or typically between two plastic sheets. the

In view of their widespread use, especially in commodity transactions such as cash checks, credit purchases, etc., it is important that persons who rely on said ID cards to identify the bearer have maximum assurance that the ID card has not been tampered with and/or Or the ID card is not a counterfeit. the

The field's response to the counterfeiting problem has involved integrating "verification features" with ID cards to prove their authenticity. The best known of these "authentication features" include a signature, eg of a party authorized to issue the ID card or of the holder. Other "authentication features" include watermarks, fluorescent materials, authentication patterns or markings and the use of polarizing stripes. These "authentication features" are integrated into the ID card in a variety of ways and they may or may not be visible in the finished card. If not, they can be detected by displaying the features under conditions that make them visible. Details on the use of "authentication features" in ID cards can be found in US 2,984,030, US 3,279,826, US 3,332,775, US 3,414,998, US 3,675,948, US 3,827,726 and US 3,961,956. the

One way to perceive information in polychromatic form (eg, as an image or pattern) is to use dye diffusion transfer imaging systems, in which one or more dyes are fabricated to diffuse in a patterned distribution. All dye diffusion transfer imaging systems are based on the same principle: changing dye solubility as a function of the amount of photographic silver halide developed. In known dye diffusion transfer imaging methods, the dye-providing species is initially mobile in an alkaline aqueous medium and becomes immobilized during processing, or is initially immobilized and becomes mobile during processing. A review of such methods has been given by C.C. Van de Sande in Angew. Chem.-Int. Ed. Engl. 22 (1983) no 3, 191-209. Further details of such methods and dye-donating substances can be found in the literature cited therein and in DE-A Nos. 1,095,115; 1,930,215; 1,772,929; 2,242,762; 2,505,248; 15,654 (April 1977). the

Wherein: Y represents the non-metallic atom required to realize a saturated or unsaturated 5- or 6-membered heterocyclic nucleus, which may carry a fused aromatic ring system, and M represents hydrogen, an alkali metal atom, a quaternary ammonium group, or a combination with all The quaternized nitrogen atom of the heterocyclic compound forms the negative charge of the inner salt. the

The term "silver halide diffusion method" refers to all black-and-white imaging methods in which a positive film is formed by diffusion inversion. The principle of the silver complex diffusion transfer reversal method (hereinafter referred to as the DTR method) has been described, for example, in US 2,352,014 and the work "Photographic Silver Halide Diffusion Processes" by André Rott and Edith Weyde, The Focal Press, London and New York, ( 1972). In the DTR process, so-called silver halide solvents are used to convert the non-developable silver halide of informationally exposed photographic silver halide emulsion layer materials into soluble silver complexes that can diffuse into the image receiving element and Therein, it is reduced by the developer (usually in the presence of physical development nuclei) to form a silver having an inverted image density value ("DTR image") relative to the black silver image obtained in the exposed areas of the photographic element. image. the

definition

The term "information carrier precursor" as used in the present disclosure denotes an intermediate product used in the realization of an information carrier. the

The term "receiving layer" as used in the present disclosure means that it has the ability to accept inkjet ink and dry quickly, ie has sufficient porosity to quickly wick away the inkjet ink dispersion medium. the

The term "porous layer" as used in the present disclosure means a layer having pores which may be in and/or in addition to the constituents of said layer, e.g. a layer comprising a porous constituent is porous layer. the

The term "diffusion inhibitor" as used in the disclosure of the present invention means a substance that inhibits the transparentization of an opaque porous layer comprising at least one pigment and at least one binder and hinders the diffusion of substances into said opaque porous layer. Can be made transparent by base paint. the

The terms "opaque" and "non-transparent" layer are used in the present disclosure to denote layers that are not transparent. The term "white opaque film" as used in the present disclosure means a white film capable of providing sufficient contrast to a transparent image such that the image is clearly perceivable. A white non-transparent film can be an "opaque film", but need not be completely opaque since there is no residual translucency, ie no light penetrates the film. The transmitted optical density, measured with a MacBeth TR924 densitometer through a visible light filter, can provide a measure of film opacity. ISO 2471 deals with the opacity of paper backings and applies when it comes to the properties of paper which govern the degree to which one sheet visually obscures prints on an underlying similar paper sheet and defines opacity as paper with a black backing The ratio (expressed as a percentage) of the light reflectance factor of a single sheet of , to the intrinsic light reflectance factor of the same sample with a white reflective backing. For example, 80 g/ ^m2 copy paper is white, non-transparent and has an optical density of 0.5 (measured by a MacBeth TR924 densitometer through a yellow filter per ISO 5-2), while metallized films typically have 2.0-3.0 optical density. Opaque porous layers used in the present invention have very high haze values, eg 98%, indicating high light scattering. Relative opacity can be defined by assigning 100% opacity (D _ref ) to the initial optical density measured from a black background under standard conditions and 0% to full transparency measured from a black background under standard conditions Opacity (D _black ), ie the optical density corresponds to the combination of the black background and the optical density of the support. The percent opacity is then given by the expression: ( _Dblack - _Dobserved )/( _Dblack - _Dref ).

As used in the present disclosure, the term "substantially transparent" means having the property of transmitting at least 75% of incident visible light without substantially diffusing it. the

The term "clearizing base paint" as used in this disclosure means a liquid which is transparent under application conditions and which comprises at least one polymer and/or at least one wax and/or at least one polymerizable substance (e.g. monomers and oligomers) and can solidify upon cooling, become solid upon evaporation of solvent or harden/crosslink, i.e. be curable, upon exposure to heat, moisture or radiation (e.g. visible light, ultraviolet rays and electron beams), which The receiving layer construction is made transparent. the

The term "opacifying base paint" as used in the present disclosure means a liquid under application conditions comprising at least one polymer and/or at least one wax and/or at least one polymerizable substance (such as a monomer and oligomers) and can solidify on cooling, become solid on evaporation of solvent or harden/crosslink, i.e. be curable, on exposure to moisture or radiation (e.g. visible light, UV rays and electron beams) The receiving layer construction is made transparent. the

The term "ability to become substantially transparent from a base paint" as used in the present disclosure means that the receiving layer construction becomes transparent at least by penetration of the base paint. This does not exclude clearing from water or solvents which provide clearing while said liquid remains in the pores, ie provide temporary clearing. the

The term "interacting" as used in the present disclosure means at least one substance capable of acting on diffusion through the porous portion of the receiving layer construction, for example by binding to, catalyzing or reacting therewith. the

The term "bound" as used in the present disclosure means capable of physisorbing at least one species that diffuses through the porous portion of the receiving layer construction, ie without changing the chemical nature of the adsorbed species. the

The term "catalytic" as used in the present disclosure means an intermolecular reaction of at least one species capable of promoting diffusion through the porous portion of the receiving layer construction, for example in processes such as electroless deposition of metals. the

The term "reactive" as used in the present disclosure means capable of reacting with at least one species diffusing through the porous portion of the receiving layer construction to produce different chemical species. the

The term "mordant" as used in the present disclosure means a substance capable of binding or immobilizing (ie providing preferential adsorption) at least one functional species. the

The term "functional species" as used in the present disclosure means a species having functional properties such that it can be detected visually with or without the aid of a suitable light source or by a detection instrument, ie is human or machine readable. Such functional species can be used, for example, to implement security features.

A substance capable of effecting and effective for binding at least one species that diffuses through the receiving layer configuration

According to a sixteenth embodiment of the information carrier precursor of the invention, said at least one substance capable of effecting and effective for binding at least one species diffusing through the formation of the receiving layer is a mordant. the

According to a seventeenth embodiment of the information carrier precursor according to the invention, said at least one substance capable of being realized and effective for binding to at least one species diffusing through the structure of the receiving layer is capable of imaging with an image transported thereto by diffusion. Dye binding. the

According to an eighteenth embodiment of the information carrier precursor of the present invention, said at least one substance capable of effecting and effective for binding at least one species diffusing through the structure of the receiving layer is capable of combining with the acid transported thereto by diffusion.

The choice of mordant for mordant or otherwise incorporating one or more diffusible dyes in dye diffusion transfer photography is determined by the nature of the dye or dyes to be mordanted. For example, it is known to mordant acid dyes with basic polymeric mordants such as polymers of amino-guanidine derivatives of vinyl methyl ketone (as described in US 2,882,156), basic Polymeric mordants and derivatives such as poly-4-vinylpyridine, N-methyl-p-toluenesulfonate of 2-vinylpyridine and similar compounds (as described in US 2,484,430) and DE-A 2009498 and DE-A Compounds described in A 2200063. Other mordants are long chain quaternary ammonium or phosphonium compounds of ternary sulfonium compounds, such as those described in US 3,271,147 and US 3,271,148, and cetyltrimethyl-ammonium bromide. Certain metal salts and their hydroxides, which form slightly soluble compounds with acid dyes, may also be used. The dye-mordant is dispersed or molecularly separated in one of the customary hydrophilic binders of the image-receiving layer, for example in gelatin, polyvinylpyrrolidone or partially or fully hydrolyzed cellulose esters. the

In US 4,186,014 cationic polymeric mordants are described which are particularly suitable for immobilizing anionic dyes, such as the sulfinate dyes released imagewise by redox reactions as described in US 4,232,107. the

Alternatively, non-polymeric mordants such as ammonium and phosphonium salts may be used. To prevent bleeding, non-polymeric mordants can be stabilized with hydrophilic organic colloids comprising a finely divided dispersion of a salt of an organic acidic composition comprising free acid moieties, as in US 3,271,147 and described in US 3,271,148. For example, gelatin which has been acylated with a dicarboxylic acid can be used as a stabilizer for the mordant. A combination of a non-polymeric phosphonium mordant and a copolymer latex comprising free weak acid groups as stabilizers for the mordant may be used, as disclosed in US 4,820,608. The non-polymeric phosphonium mordant may, for example, comprise at least one long chain hydrocarbon group. the

In addition, the component receiving layer may be lightly crosslinked to provide desired characteristics, such as water repellency and non-blocking properties. However, the degree of crosslinking should be such that neither the diffusion of the functional species or precursors of the functional species nor the penetration of the base paint should be substantially affected. Crosslinking can also be used to provide abrasion resistance and prevent fingerprints from forming on the element through processing. There are a number of known cross-linking agents (also known as hardeners) that will function to cross-link the film-forming adhesive.

The refractive indices of these pigments are given in the table below:

The use of aluminum oxide (alumina) in the receiving layer is disclosed in several patents, such as in US 5,041,328, US 5,182,175, US 5,266,383, EP 218956, EP 835762 and EP 972650. the

Silica as a pigment in receiver elements is disclosed in numerous old and new patents, such as US 4,892,591, US 4,902,568, EP 373573, EP 423829, EP 487350, EP493100, EP 514633, etc. Different types of silica can be used such as crystalline silica, amorphous silica, precipitated silica, gelled silica, fumed silica, spherical and non-spherical silica, calcium carbonate complexes Mixed silica as disclosed in US 5,281,467, and silica with internal porosity as disclosed in WO 00/02734. The use of calcium carbonate in the receiving layer is described, for example, in DE 2925769 and US 5,185,213. The use of aluminosilicates is disclosed, for example, in DE 2925769. Mixtures of different pigments can be used. the

In alternative embodiments, the primary pigment may be selected from organic particles such as polystyrene, polymethylmethacrylate, silicone, melamine-formaldehyde condensation polymer, urea-formaldehyde condensation polymer, polyester and polyamide. Mixtures of inorganic and organic pigments can be used. Most preferably, however, the pigments are inorganic pigments. the

The pigment must be present in sufficient coverage to render the receiving layer sufficiently opaque and porous. The binder to total pigment weight ratio in the receiving layer preferably has a lower limit of about 1:50, most preferably 1:20 and an upper limit of about 2:1, most preferably 1:1. If the amount of the pigment exceeds the upper limit, the strength of the receiving layer itself is lowered, and the resulting image thus tends to be inferior in resistance to shading and the like. On the other hand, if the ratio of the binder to the pigment is too high, the resulting receiving layer has lowered ink absorbing ability and thus the formed image may be deteriorated. the

The clearing method depends on the fact that on the one hand the refractive index of the pigment and on the other hand the refractive index of the base paint (see description below) which penetrates the receiving layer construction should be matched to each other as closely as possible. The closer the refractive indices are matched, the better transparency will be obtained after impregnation of the receiver layer by the base lacquer. the

The most preferred pigments are of the silica type, more particularly amorphous silica having an average particle size of from 1 micron to 15 microns, most preferably from 2 to 10 microns. The most useful commercially available compound is the amorphous precipitated silica type SIPERNAT 570, trade name from Degussa Co. It is preferably present in the receiving layer in an amount of 5 g/m ² to 30 g/m ² . It has the following properties:

- Specific surface area (N ₂ absorption): 750m ² /g

-Average particle size (Multisizer, 100 micron capillary action method): 6.7 microns

-DBP [dibutyl phthalate] adsorption: 175-320 g/100 g

- Refractive index: 1.45-1.47. the

Since a typical UV curable basecoat composition has a refractive index of about 1.47-1.49, it is apparent that there is a good match to the refractive index of this particular silica type and will result in good transparency. the

Other useful precipitated silica types include SIPERNAT 310, 350, and 500, AEROSIL grades (trademark of Degussa-Hüls AG), and SYLOID types (trademark of Grace Co.). the

Receiver layers containing porous alumina pigments (e.g. MARTINOX GL-1) will not become fully transparent when impregnated by an acrylate/methacrylate based basecoat with a refractive index of 1.47-1.49, since its refractive index is 1.6 . However, base lacquers with a higher refractive index may be used, for example comprising N-vinylcarbazole as a comonomer. the

According to the method according to the invention for producing an information carrier, the adhesion of the base-impregnated receiver layer to the rigid sheet or support is improved by subsequent curing (eg UV curing). the

Adhesive for receiving layer

The receiving layer binder can be water-soluble, solvent-soluble or latex, and can be selected from a series of compounds known in the art, including hydroxyethyl cellulose; hydroxypropyl cellulose; hydroxyethyl methyl Cellulose; Hydroxypropylmethylcellulose; Hydroxybutylmethylcellulose; Methylcellulose; Sodium carboxymethylcellulose; Sodium carboxymethylhydroxyethylcellulose; Water-soluble ethylhydroxyethylcellulose; Sulfuric acid Cellulose; Polyvinyl Alcohol; Vinyl Alcohol Copolymer; Polyvinyl Acetate; Polyvinyl Acetal; Polyvinylpyrrolidone; Polyacrylamide; Acrylamide/Acrylic Copolymer; Polystyrene, Styrene Copolymer; Acrylics or methacrylic polymers; styrene/acrylic copolymers; ethylene-vinyl acetate copolymers; vinyl methyl ether/maleic acid copolymers; poly(2-acrylamido-2-methylpropanesulfonium acid); poly(diethylenetriamine-co-adipic acid); polyvinylpyridine; polyvinylimidazole; polyethyleneimine epichlorohydrin modified; polyethyleneimine ethoxylated; Polyethylene oxide; polyurethane; melamine resin; gelatin; carrageenan; dextran; gum arabic; casein; pectin; albumin; starch; collagen derivatives; collodion and agar. the

Preferred binders for use in the practice of the present invention are polyvinyl alcohol (PVA), vinyl alcohol copolymers) or modified polyvinyl alcohols. Most preferably, the polyvinyl alcohol is silanol-modified polyvinyl alcohol. The most useful commercially available silanol-modified polyvinyl alcohols can be found in the POVAL R polymer series (trade name of Kuraray Co., Japan). The R polymer series includes grades R-1130, R-2105, R-2130, R-3109, which differ primarily in the viscosity of their respective aqueous solutions. The silanol groups are reactive towards inorganic substances such as silica or alumina. R-polymers can be easily crosslinked by changing the pH of their aqueous solutions or by mixing with organic substances, and can form water-resistant films. the

Latex ratio decreased. For too high a pigment/latex ratio, the receiver layer becomes too powdery. use

For W-300, the best image sharpness was observed at total pigment to total latex weight ratios of 2.0-3.2. Furthermore, the presence of extremely high latex concentrations inhibitably reduces the rub resistance of printed images.

Alternatively, the inkjet image on the outermost receiver layer becomes increasingly sharper as the latex concentration in the outermost opaque porous layer decreases. exist

With W-300 as the pigment, the best image quality was found at 2.0-3.2:1 total pigment to total latex. Increased latex content in the outermost layer of the receiver construction also improves its offset printability due to improved adhesion of the offset ink.

Other examples of high quality polymeric supports useful in the present invention include opaque white polyesters and extruded blends of polyethylene terephthalate and polypropylene. Polyester film supports and especially polyethylene terephthalate are preferred due to their outstanding dimensional stability. When such polyesters are used as a support material, a subbing layer may be employed to improve the bonding of the receiving layer construction to the support. Adhesive layers useful for this purpose are well known in the photographic art and include, for example, polymers of vinylidene chloride such as vinylidene chloride/acrylonitrile/acrylic acid terpolymer or vinylidene chloride/methyl acrylate/itacon acid terpolymer. the

The method typically produces a visually detectable (i.e. human readable), detectable by use of light via fluorescence or phosphorescence (i.e. human readable with an appropriate light source) or machine readable (e.g. electronically or magnetically machine readable). readable) functional classes. the

The species or species diffused through the receiving layer configuration may themselves be visually detectable (i.e., human-readable), detectable by the use of light via fluorescence or phosphorescence (i.e., by an appropriate light source). Human-readable) or machine-readable (e.g., electronically or magnetically) machine-readable, that is, functional. the

As a final alternative, species diffusing through the receiving layer construct react either by themselves or with other species to produce a visually detectable (i.e., human-readable) species that can be detected by using light via fluorescence or phosphorescence. (i.e. human-readable with the assistance of an appropriate light source) or machine-readable (eg electrically or magnetically) machine-readable, ie functional. the

By curing, the cohesion of the receiving layer construction and the adhesion between the receiver and the support are greatly improved, so that the information carrier becomes tamper-resistant in this way, since it has become extremely resistant to mechanical and chemical influences . the

Equipment for UV curing is well known to those skilled in the art and is commercially available. For example, curing can be performed by medium pressure mercury vapor lamps, with or without electrodes, or by pulsed xenon lamps. These UV light sources are usually equipped with cooling equipment, equipment for removing the ozone generated and optionally a nitrogen inflow to exclude air from the surface of the product to be cured during radiation processing. Typically an intensity of 40-240 W/cm in the 200-400 nm spectral region is employed. An example of a commercially available UV curing unit is the DRSE-120 conveyor with VPS/1600 UV lamp (an ultraviolet medium pressure electrodeless mercury vapor lamp) from Fusion UV Systems Ltd., UK. The DRSE-120 conveyor can run with a width of 20 cm and a length in the transport direction of 0.8 cm at different transport speeds and with different UV power settings. Furthermore, it can also be used with metal halide doped mercury vapor or XeCl excimer lamps, each of which has its own specific ultraviolet emission spectrum. This allows for a higher degree of freedom in the formulation of the curing composition: more efficient curing is achieved using lamps with the most appropriate spectral characteristics. Pulsed xenon flash lamps are commercially available from IST Strahlentechnik GmbH, Nürtingen, Germany. the

According to a first embodiment of the method of manufacturing an information carrier according to the invention, said method further comprises the step of applying a pattern to the outermost surface of said receiving layer construction using conventional printing methods, preferably non-impact printing or impact printing , and inkjet printing is particularly preferred. the

According to a second embodiment of the method of manufacturing an information carrier according to the invention, said method further comprises the step of applying a pattern, preferably non-impact, to the opaque and porous part of the outermost layer of said receiving layer construction using conventional printing methods Type printing or impact printing, and inkjet printing is particularly preferred. the

In a most preferred embodiment, the digitally stored information is individualized information different for each individual item present on the information carrier. For example, the personalization information may be a unique and unique card number assigned to the future holder of the card, or an end date of the card's validity, or personal data of the future holder, such as date of birth and/or photograph. Furthermore, when the information carrier is to be cut into multiple ID cards, the inkjet printing step is repeated on multiple areas of the support aligned with the security print pattern (if present), thereby providing each object with a different personalization information. the

According to the fourth embodiment of the method for manufacturing an information carrier according to the present invention, the permeable transparent base paint further includes functional components such as fluorescent or phosphorescent compounds, fluorescent or phosphorescent fibers, and a characteristic smell such as fragrance or fragrance compound or compound mixture. the

According to an eighth embodiment of the method of manufacturing an information carrier according to the invention, an embossable layer is applied to the surface of a rigid sheet or support and/or to the surface of any layer comprised in the information carrier (such as the information carrier outermost surface) and then emboss the embossable layer as a hologram. the

According to a ninth embodiment of the method of manufacturing an information carrier according to the present invention, a black image is printed on the outermost surface of the receiving layer construction and the black image is developed into a relief pattern by ultraviolet irradiation. the

According to a tenth embodiment of the method of manufacturing an information carrier according to the invention, metal fibers or strips in a hardenable composition are applied to the outermost surface of the receiving layer construction. the

According to an eleventh embodiment of the method of manufacturing an information carrier according to the invention, a pattern or a metal core or a heavy metal sulphide is applied under the embossed pattern adjacent to the structured surface of the receiving layer close to said rigid sheet or support , and a silver layer is obtained under said embossed pattern by a method (optionally a photographic method) that produces a discontinuous silver layer on the nucleation layer using silver salt diffusion transfer. the

When the information carrier indicates that it will later be cut into a plurality of identification cards, the security print is applied repeatedly on several areas of the web or sheet by a step-by-step repeating process, thereby producing a plurality of identical objects. These multiple identical objects are distributed on the support according to a fixed pattern such as a rectangular grid. Furthermore, the application and curing of the varnish is repeated on a plurality of areas of the information carrier aligned with the already existing plurality of different objects consisting of optional security printing and personalized information. the

An opaque background can be achieved by choosing a base paint that penetrates into the receiver construction, but whose refractive index is so different from that of the pigment that it cannot render the receiver construction transparent. the

Another way to keep the background opaque is by curing the base paint composition before it can substantially penetrate into the receiving layer construction. The penetration behavior of the clearcoat and basecoat is reversed with respect to the first embodiment. This behavior is also controlled by viscosity and/or affinity and/or penetration time. the

inkjet printing

If inkjet printing is used in the method of manufacturing an information carrier according to the invention, it can be achieved by any known technique known in the art. In the first class of methods, a continuous stream of droplets is generated by applying a pressure wave pattern. This method is called continuous inkjet printing. In a first embodiment, the droplet stream is divided into electrostatically charged, deflected and recovered droplets, and droplets that remain uncharged, continuing their course without being deflected, and an image is formed. Alternatively, the charged deflected stream forms the image and the uncharged undeflected jet is recollected. In this variant of continuous inkjet printing, several jets are deflected to different degrees and thus record the image (multi-deflection system). the

According to a second inkjet method, ink droplets can be produced "on demand" ("DOD" or "drop-on-demand" method), whereby the printing device ejects droplets only when they are used for imaging on a receiver, thereby Avoid the complications of droplet charging, deflection hardware, and ink recollection. In drop-on-demand jetting, ink droplets can be formed by means of pressure waves generated by mechanical movement of piezoelectric transducers (the so-called "piezo method"), or by means of discrete thermal propulsion (the so-called "bubble jet method"). " method or the "thermal spray" method). the

Ink compositions for inkjet typically include the following ingredients: dyes or pigments, water and/or organic solvents, humectants such as glycols, detergents, thickeners, polymer binders, preservatives, and the like. It is readily understood that the optimum composition of such inks depends on the inkjet method used and the nature of the substrate to be printed. Described ink composition can roughly be divided into:

- water-based: drying mechanisms include absorption, osmosis and evaporation;

-Oil-based: drying includes absorption and penetration;

- solvent-based: the drying mechanism mainly involves evaporation;

- thermal fusion or phase change: the ink carrier is liquid at jetting temperature but solid at room temperature; drying is replaced by solidification;

- UV curable: drying is replaced by photopolymerization. the

The colorants present in inkjet inks may be dyes which are molecularly soluble in the ink fluid, such as acid dyes bound in the ink receiver by cationic mordants, or they may be finely dispersed in the ink fluid of pigments. the

Transparent base paint composition

Substantial penetration of said at least one opaque porous layer by the base paint may be achieved by controlling the penetration time and/or affinity and/or viscosity of the composition. The viscosity of the clearing base paint composition is adjusted to ensure fast penetration and thus fast clearing. the

According to a fourteenth embodiment of the method of manufacturing an information carrier according to the present invention, the base varnish is a photopolymerizable base varnish. the

The method of clearing depends on matching the refractive indices of the pigment and the base paint permeating the receiving layer construction to each other as closely as possible. The closer the indices of refraction are matched, the better transparency will be obtained after infiltration of the receiver layer construction from the base paint. Therefore, the choice of base paint components must meet this requirement. Other constraints on the composition of the base paint depend on whether the base paint needs to be curable and, if so, what curing method has been selected. the

According to a fifteenth embodiment of the method of manufacturing an information carrier according to the present invention, the difference between the refractive index of the pigment and the refractive index of the transparentizing base varnish is not more than 0.1. the

A good match of , and thus good transparency. the

Using a 100 micron wirebar followed by drying at 50°C yielded an opaque porous layer with a layer thickness of 22 microns and an optical density of 0.19 as measured by a MacBeth RB918-SB densitometer with a visible light filter and A sheet of black cardboard with a density of 1.35 was placed under a transparent polyethylene terephthalate support. An optical density of 0.06 measured by a visible light filter through a white background beneath a transparent polyethylene terephthalate support indicates some transparency, but the "opaque" porous layer is due to the layer's composition from The Haze-Gard Plus unit from BYK-GARDNER provides a white opaque film with an extremely high haze of 97% measured according to ASTM D 1003. the

Model experiments were performed from liquids to determine what refractive index difference is acceptable for the opaque porous layer described above without significant loss in optical density. The results are given in Table 2 together with the optical densities obtained by clearing with base paints having the composition given in Table 3 below:

Based on the optical densities achieved by the base paints given in Table 3, extrapolation gives a refractive index value of approximately 1.52 for the pigment in the opaque porous layer. the

Solutions of various surfactants were also applied to the opaque porous layer above and after drying in a drying cabinet, the portion of the opaque porous layer to which the surfactant solution had been applied was made from a 50 micron wire with the base paint given in Table 3 below. Rod coating. Under the same conditions, overcoating the aforementioned opaque porous layer with this basecoat without the application of a surfactant solution provided a layer with an optical density of 1.40 and a haze of 6%, measured as described above. the

The resulting transparency was rated visually using the following criteria:

Evaluate the 0 The wetted area is completely transparent 1 Wetted area is very slightly opaque 2 Wetted area is fairly opaque 3 Wetted area moderately opaque 4 Wetted area is almost completely opaque 5 Wetted area is completely opaque

The results are given in Table 4:

Table 4:

These results can only be considered as a qualitative indication of the diffusion inhibiting properties, since the experiments did not take into account the effective degree to which the particles were covered by the surfactant, nor the purity of the surfactant. Complete opacity was only observed with INHIBITOR 104 (2-thiohexadecyl, 3-sulfobutyl-benzimidazole-6-sulfonic acid sodium salt). At least one member from cationic, anionic and nonionic surfactants was found to exhibit diffusion inhibiting properties. The presence of long-chain alkyl, alkenyl, and fluoro-alkyl groups was found to be beneficial, however, with the notable exception that INHIBITOR 03 (a nonionic surfactant with poly(alkylene oxide) groups) showed no diffusion inhibition sex. the

By applying water and INHIBITOR 104 (2-thiohexadecyl, 3-sulfobutyl-benzimidazole-6-sulfonic acid sodium salt) in various concentrations of aqueous solution or water ethanol solution and changing the application to the above opaque porous The amount of layer surface to quantitatively study the diffusion inhibition properties of INHIBITOR 104. After drying at ambient conditions for 30 minutes, the portion of the opaque porous layer to which the surfactant solution had been applied was overcoated with the base paint given in Table 3 of Example 1 of the present invention with a 50 micron wire bar. the

For each surfactant, the optical density observed for the portion of the opaque porous layer to which the surfactant had been applied was measured from a black cardboard sheet under a transparent polyethylene terephthalate support. the

The spots observable after penetration of the basecoat and UV curing vary in size depending on the liquid applied and for some liquids by the amount of liquid applied. In some experiments (including those with water), a halo effect with an opaque outer ring and a transparent center was observed. The spot size used for the densitometric measurements was 4 mm, which is not much smaller than some spots that lead to anomalous optical density values in the case of spots with halos. the

A high optical density value indicates a high degree of clearing as it is a combination of the optical density of the black cardboard sheet and the optical density of the polyethylene terephthalate support being measured. A low optical density value indicates a low degree of clearing, as it is the optical density of the opaque porous receiving layer being measured. The results are summarized in Table 5 below, with magnitude or magnitude/ ^cm in parentheses.

table 5:

The results in Table 5 show that 1 microliter, 2 microliters and 5 microliters of water provided no inhibition of the clearing process, while 10 microliters of water was sufficient to provide partial inhibition of the clearing process. the

The results in Table 5 clearly show that the presence of ethanol in the carrier medium reduces the inhibitory effect of INHIBITOR 104 for the same amount of INHIBITOR 104 . This is presumably due to the preferential adsorption of ethanol relative to water and INHIBITOR 104. In the absence of ethanol, precipitation of 10 ^-3 -2x10 ^-3 g/cm ² appears to be required for effective inhibition. The haze of this layer was measured as 98% as described above.

The UV-curable clearing basecoat compositions given in Table 2 were coated with a 50 micron wire bar at various times after application of ... microliters of water or 10 microliters of INHIBITOR 104 in 10% water in The durability of the inhibitor was investigated by measuring the optical density of black cardboard sheets under a polyethylene terephthalate support. The results are given in Table 6, where magnitudes or magnitudes/ ^cm2 are provided in parentheses.

Table 6:

These results show that no clearing was observed with water until more than 5 minutes had elapsed, ie until the water had evaporated, ie the water inhibited the clearing process. On the other hand, with a 10% aqueous solution of INHIBITOR 104, the use of the base paint had no significant effect on the clearing process even after a 10 minute delay between applying the 10% aqueous solution of INHIBITOR 104 and applying the clearing base paint. Influence. This clearly shows that the inhibitory effect of INHIBITOR 104 is permanent whereas that of water is temporary. the

The possible diffusion-inhibiting effect of INHIBITOR 104 on inkjet images was then investigated using inkjet images produced by an Epson Photostylus R800 inkjet printer with pigment-based aqueous inks. The opaque porous layer described above was first spotted with a 10% aqueous solution of INHIBITOR 104, dried and then printed yellow, magenta, cyan and black areas on both the INHIBITOR 104 treated areas and non-INHIBITOR 104 treated areas. Optical density was measured by a Macbeth RD918SB reflection densitometer using visible blue, green and red filters from the black paper sheet under the transparent support of the opaque porous layer. The results are summarized in Table 7 below:

Table 7:

The results in Table 7 clearly show that treatment with INHIBITOR 104 increases the optical density up to 0.86, indicating that diffusion into the opaque porous layer has been inhibited by the presence of INHIBITOR 104. the

The inkjet images were then coated with the clearing basecoats given in Table 3 using a 50 micron wire bar. Optical density was measured by a Macbeth RD918SB reflection densitometer using visible blue, green and red filters from the black paper sheet under the transparent support of the opaque porous layer. The results are summarized in Table 8 below:

Table 8:

Areas pretreated by INHIBITOR 104 and subsequently inkjet by the color image remained completely opaque after the UV curable overlay was provided, whereas areas not pretreated by INHIBITOR 104 were completely transparentized. the
