Definitions

  • the present invention relates to heat-scalable labels or like marking elements for applying markings or decorative effects to textile articles, fabrics or other sheet materials or to leather, wood, glass, plastics and so on, and to methods of marking articles, for the purpose of obtaining markings or decorative eifects which are substantially resistant to wear, and in the case of textile and like articles are resistant also to repeated cleaning or washing of such articles.
  • the polyamides used may be soluble polyamides or copolyamides which can be converted into a highly inert and insoluble form by a curing agent in the presence of a cross-linking agent containing alkylol or alkoxy-alkyl groups, and such cross-linking agent may in some cases be a formaldehyde resin.
  • a cross-linking agent containing alkylol or alkoxy-alkyl groups
  • cross-linking agent may in some cases be a formaldehyde resin.
  • Other compounds which can be used similarly are dispersions of an acrylic resin capable of being cross-linked at an elevated temperature.
  • the present invention is directed to a label or like marking device which offers substantially all the advantages of heat transfers produced according to the abovenoted patent but which can be more economically produced and which has the further important advantage that the time cycle required for applying or bonding the marking to the article to be marked can in many cases be reduced as compared with the procedure involved in the above-noted patent, while, furthermore, the step of removing the temporary support can be avoided which results in a saving of time.
  • a marking element comprises a flexible support incorporating a heat curing film-forming resin system in the presence of alkylol or alkoxy alkyl groups and under acid conditions, and an information-bearing marking printed on said support, to provide a marking element which substantially withstands various treatments to which the surface may be subjected.
  • the ink used for producing the marking or decorative pattern preferably employs a medium consisting of a similar resin to that applied to the support so that after the application of heat and pressure the printed label, when bonded to a textile article, is not aifected by repeated laundry or dry (chemical) cleaning treatments to which the article may be subjected.
  • the support can be formed of a relatively inexpensive material such as paper.
  • a thin permeable paper the presence of such support after bonding the label to the article is of no disadvantage and provides a backing for the marking or pattern carried by the label.
  • the invention also contemplates the use of a fabric, for example a fine woven cotton fabric, or a thin foil of plastics.
  • the marking produced on the support is visible at all times, control of the printing or other operations used for producing the marking can be more readily effected than in cases where, as in the above-noted patent, the printed marking is overlaid by the temporary support and is thus not readily available for inspection, while, furthermore, the present invention otfers the advantage that printing is effected in the normal configuration and not in reverse as is often necessary when the support is a temporary support which must be removed from the article after transfer has been effected.
  • the fibreor film-forming resin may consist of a solubilised linear polyaimide of the character described in the aforesaid patent and may consist of a nylon-type polyamide which has been converted into a soluble form containing alkoxy alkyl groups by treatment with an aldehyde such as formaldehyde, as described for example in British specification No. 591,382.
  • Materials of this type are commercially available under the trademarks Calaton CA and CB (made by I.C.I. Ltd., and believed to be substantially identical to the substance previously sold under the trademark Maranyl, or BCI Type 800 resins made by Belding Chemical Industries).
  • alcohol-soluble copolyamides may be used in conjunction with a cross-linking agent containing alkoxy alkyl groups, and in this. case the cross-linking agent may be a formaldehyde resin containing alkoxy alkyl groups.
  • a still further alternative is a cross-linking acrylic resin conveniently in the form of an aqueous dispersion such as that sold under the trademarks Plextol (made by Rohm and Haas of Darmstadt) or Hycar (British Geon, Ltd.).
  • Polyamide and copolyamide resins of the above types are soluble in alcohols or alcohol/water mixtures, and such resins may be applied in the form of alcohol or 'alcohol/water solutions.
  • Acrylic resin dispersions may be used in the commercially available form or the dispersion may be thickened by suitable additions if required.
  • solutions or dispersions are used as coating or impregnating agents and are self-curing under acid conditions.
  • they may contain an organic acid curing agent or an acidyielding compound such as an anhydride or an ammonium or amine salt.
  • Suitable curing agents are preferably those acids or compounds which are solid at normal temperature.
  • a typical organic acid is citric acid or alternatively ammonium citrate can be used.
  • Such acids are convenient for the purpose because at room temperature they are substantially inactive in promoting cross-linking so that labels produced by coating a support with a resin solution and such a soluble organic acid, have a satisfactory shelf life and are not liable to be affected by long storage periods; nevertheless curing occurs rapidly and effectively when the labels are applied to the article to be treated, such application being conveniently at a temperature of the order of 150 to 250 C., preferably from 180 to 250 C., and at a specific pressure of about 20 to 100 lbs. per square inch.
  • the desired pattern or marking is printed on the support and then dried.
  • the printing ink used may consist of a medium which also is a heat curing resin together with suitable pigments and other additions appropriate to a printing medium, and the printing of the desired design or pattern may be etfected by any normal printing processes, for example letterpress, oifset litho, flexographic or gravure processes, or it may be produced by screen printing.
  • a continuous coating of the resin mixture may be applied to form a protective surface on the marking element.
  • a continuous outer layer is applied as an overcoating on the printed or decorative marking there is a higher degree of protection of the marking, and it may even be possible to use normal types of printing media, for example flexographic shellac-based inks.
  • the opposite face of the support 1 receives a printed pattern or design such as is indicated typically at 3 which is applied by a printing process in which the medium of the printing ink consists of a resin solution or dispersion. If desired an overcoating consisting of a continuous layer of the resin solution or dispersion is applied.
  • the pattern or design is produced by direct printing and that the design or pattern is visible to the operator when applying the label to the article to be marked.
  • Such application is effected by means of a suitable heat-sealing press which bonds the coated rear surface of the support 1 to the article to be marked and efiects curing and cross-linking of the resin component of the impregnation of the support, of the printed marking thereon and of any continuous layers which may be present to form a highly inert and resistant marking on the surface to be marked.
  • This table comprises cross-linking acrylic resins which may be polymers or copolymers of alkyl esters of acrylic acid or methacrylic acid comprising N-alkoxyalkyl acrylamide.
  • acrylic resins which may be polymers or copolymers of alkyl esters of acrylic acid or methacrylic acid comprising N-alkoxyalkyl acrylamide.
  • Typical examples of commercially available products which may be used in accordance with the present invention are the following:
  • Plextol B58a Plextol M17a
  • Hycar 2679' The commercially available dispersions may be utilised in carrying out the present invention in the form received by the makers.
  • the components other than the resin dispersion are pre-dispersed in the water before the resin is added.
  • Different resins can be used for printing particularly in those cases where the information-bearing marking is protected by an additional coating as in Examples III, VIb and VII, or when the ink can be caused to bond strongly to the permanent support itself rather than the coating or impregnating resin as in the case of Examples II and VIa.
  • plasticisers should be present in the coating or impregnating media and in the printing inks.
  • polyamide solu tions and inks containing polyamides that is to say, the coating solutions of Table I and printing inks Nos. 1 to 5, 7 and 8, any of the following plasticisers may be used but it should be understood that this list is not exhaustive and that other suitable plasticisers are available and could be used.
  • any of the following plasticisers can be used but again this list is not exhaustive.
  • plasticisers of Table V will normally be pro-emulsified with an equal weight of water and in the presence of 1% of a non-ionic wetting agent, for example one of the products sold under the trademark Nonex supplied by Union Carbide & Chemical Corporation.
  • ink No. 14 All the printing inks in Table III including ink No. 14 are suitable for use in the fiexographic or gravure printing processes. Inks Nos. 1 to 13 are also suitable for use by the screen printing process and in this case the industrial ethanol may be replaced by n-butanol or diacetone alcohol.
  • cross-linking agent referred to in solutions 2 and 3 of Table I and in the corresponding printing inks Nos. 4, 5, 7 and 8 comprise compounds of formaldehydes with for example urea and melamine containing alkoxy alkyl groups which in some cases may be formaldehyde resins. These compounds may be selected from the following table which illustrates typical examples of suitable compounds but is not an exhaustive list of cross-linking agents.
  • the fluid coating or impregnating media may be prepared by high-speed stirring except where commercially available dispersions are used in the form received by the makers.
  • the pigments may be introduced by ball milling and additional substances such as the curing agents for example triammonium citrate or citric acid added with stirring.
  • Coating or impregnating mixtures according to Table I or Table II may be applied to the permanent support in any convenient way as a continuous coating or by causing a continuous strip of the support material to pass through the coating or impregnating mixture.
  • the support is dried at a temperature not exceeding that at which substantial crosslinking of the resin occurs, preferably below C.
  • the support is then printed with the desired information-bearing marking or pattern and the printed labels or label strip is then dried again at a temperature below that at which substantial cross-linking occurs, generally below 100 C.
  • Labels produced with such resin systems are applied under heat and pressure in a suitable heat sealing press at a temperature in excess of the softening temperature of the resin used. At these temperatures rapid cross-linking of the resin occurs with the formation of a permanent bond to the article being marked, the bond and the label itself then being capable of withstanding repeated laundering and dry chemical cleaning operations.
  • EXAMPLE I A 40 gm. per sq. m. high wet strength paper of high absorbency was impregnated with 15 gm. per sq. m. (dry weight) of a mixture selected from Table I or Table II.
  • a coating of 25 gm. per sq. m. was applied to one side only, using the same mixture selected for impregnation and the coating dried, at a temperature below that at which the resin cross-links rapidly, i.e. below 100 C.
  • a design was then printed repetitively, using an ink selected from Table III, Nos. 1 to 13 using the resin selected for impregnation.
  • Drying was carried out at a temperature below that at which the resin cross-links rapidly, i.e. below 100 C.
  • the paper is manipulated in the form of a continuous strip which is formed into rolls. Labels were cut from the rolls prepared as above and were tested by being applied to a range of textile fabrics including cotton, linen, nylon, polyester, glass cloth, using a heat-sealing press giving application conditions of 200 C., 4 seconds, 40 lbs. per sq. in.
  • the fabrics with applied labels were then subjected to many cycles of the appropriate laundry treatment and showed good resistance up to 30-50 successive treatments.
  • EXAMPLE II An 80 gm. per sq. in. closely woven cotton fabric was coated, substantially on one side only, with 50 gm. per sq. m. of a mixture selected from Table I or Table II.
  • EXAMPLE III A 50 gm. per sq. m. viscose non-woven fabric was impregnated with 20 gm. per sq. m. of a mixture selected from Table I or Table II followed by coating with a similar mixture to about 30 gm. per sq. -m. on one side only.
  • a repetitive design was then printed on the uncoated side using inks freely selected from Table III, Nos. 1 to 14.
  • the printed side was then coated with a further 15 gm. per sq. m. of the mixture used for impregnation and coating.
  • Labels cut from these rolls were tested in a similar way to Example I, and were found to be legible when the fabric was worn out.
  • EXAMPLE IV A 45 gm. per sq. m. high wet strength, highly absorbent paper, comprising of carbon black, was impregnated and coated as Example I. This was then cut into sheets of a suitable size for screen printing.
  • EXAMPLE V A 35 gm. per sq. m. high wet strength, highly absorbent paper, was impregnated with 18 gm. per sq. m. of an ink selected from Table III, Nos. 1 to 13. It was then coated with 30 gm. per sq. m. of a mixture selected from Table I or Table II, using the same resin type.
  • Printing was carried out using a contrasting colour selected from Table III, Nos. 1 to 13.
  • EXAMPLE VI (a) A 100 gm. per sq. m. high wet strength paper of low absorbency was coated on one side only with 50 gm. per sq. m. of a mixture selected from Table I or Table II.
  • Cut labels were intended for use by a linen hire organisation and are intended to carry in addition to the printed information individual markings. Cut labels were applied on to cotton or linen overalls at 250 C., 4 seconds, 60 lbs. per sq. m. in., and after application additional information was inserted such as the name of the lessee, date of contract, etc., by means of a laundry marking ball point pen (as supplied by Scripto Ltd). Labels formed in this way were found to withstand about 50 laundry operations.
  • Such transfer layer was prepared by coating a 60 micron film of cellulose triacetate with 15 gm. per sq. m. of a mixture selected from Table I or Table II and then dried. The dried coating was placed in contact with the label and subjected to heat and pressure under the same conditions as the labels, and the support film peeled off or allowed to detach itself.
  • EXAMPLE VII A 38 micron film of regenerated cellulose was printed with an ink freely selected from Table III, Nos. 1 to 13 and then coated on both sides with 20 gm. per sq. m. of a mixture selected from Table I or Table II.
  • EXAMPLE VIII Labels were prepared in a similar way to Example I using a coating solution selected from Table I with three parts of a plasticiser selected from Table IV.
  • EXAMPLE IX Labels were prepared in a similar way to Example I, using a coating mixture selected from Table II with 10 parts per parts of resin dispersion of a plasticiser selected from Table V.
  • labels according to the present invention may be economically produced since an inexpensive class of support material may be used, typically a soft and absorbent paper, which is coated or impregnated with the resin solution or dispersion in fluent form, and then dried. Because of the absence of a temporary support the application of heat from the presser means used for applying it to the article to be marked is operative rapidly, permitting the application and bonding of the label to the article to be effected in a period of not more than 7 seconds at most in practical cases. Because the printed marking on the label is visible at all times, control of the printing during production of the labels is facilitated, and this easy visibility is also of advantage in facilitating the correct application of the label to the article to be marked.
  • an inexpensive class of support material typically a soft and absorbent paper, which is coated or impregnated with the resin solution or dispersion in fluent form, and then dried. Because of the absence of a temporary support the application of heat from the presser means used for applying it to the article to be marked is operative rapidly, permitting the application and bonding of the
  • marking elements having information-bearing markings printed thereon.
  • the resin component of these marking elements is converted into an insoluble, abrasionand wash-resistant compound by heat and pressure.
  • the printing ink itself is either converted into a similar compound or the printing ink is protected on each side by continuous layers of such cured compounds.
  • the resulting marking elements are highly resistant to influences operative throughout the life of the article being marked, including resistance to wear and resistance to cleaning operations such as cleaning solvents, without substantial degradation of the information carried by the marking element.
  • a presser member operative on the exposed surface of the transfer which embodies an engraved surface pattern or grain which may give a characteristic appearance, for example, a natural textile appearance, to the label while in position on the article.
  • a marking element permanently attachable by heat and pressure to a surface to be marked, comprising a paper-like flexible permanent support sheet completely impregnated with a heat curing film-forming resin system, a further coating of a heat curing film-forming resin system on one side of said support and an information-bearing marking imprinted on the other side of said support, said marking also including a heat curing, filmforming resin system and said film-forming resin systerns selected from the group consisting of soluble polyamides, soluble copolyamides, and cross-linking acrylic resins and including alkylol or alkoxy alkyl groups under acid conditions for conversion of said resin system under said heat and pressure into an inert, insoluble and abrasion-resisting substance in situ on the surface to be marked.
  • a marking element according to claim 1, wherein the information-bearing marking is produced by means of a printing ink including a cross-linkable resin system.
  • a marking element according to claim 6 wherein the cross-linking agent is a formaldehyde resin containing alkoxy alkyl groups.
