Definitions
- the present invention relates to new printing inks for book or offset printing which contain microcapsules containing color formers, alkali salts of rosin as binders and glycols or glycol ethers as solvents.
- the invention also relates to a method for producing pressure-sensitive, carbon-free transmission systems using these printing inks.
- Reaction copy papers are well known. Their mode of operation consists in that a color-forming component, which is usually dissolved in organic solvent and encased in a microcapsule, and a color-developing component are brought into contact with one another and thereby react to form a color.
- a color-forming component which is usually dissolved in organic solvent and encased in a microcapsule
- a color-developing component are brought into contact with one another and thereby react to form a color.
- encapsulated color former and developer are applied together in one layer to the carrier material, generally paper.
- Multilayer systems usually consist of two or more sheets of paper lying on top of one another, in which a donor layer containing a microcapsule is applied to the back of the top sheet and a receiver layer containing the developer is applied to the front of the sheet below it. In both cases, the microcapsules are destroyed by the pressure when writing, and a copy is produced by the reaction of the color former and color developer.
- Inks containing microcapsules are known. However, the printing inks described do not contain any solvents.
- the invention was based on the object of providing further printing inks which can advantageously be used for the production of carbonless reaction papers.
- printing inks for book or offset printing which contain microcapsules containing color formers, alkali metal salts of rosin as binders and glycols or glycol ethers as solvents.
- a process for the production of pressure-sensitive, carbon-free transmission systems according to the technique of book or offset printing has been found, which is characterized in that these printing inks are used for this. 5
- microcapsules for the printing inks according to the invention
- plastic capsules in dry form are preferably used.
- Capsules made of polyamides or polyurethanes and in particular those made of melamine-formaldehyde resins or acrylic acid derivatives may be mentioned individually.
- the production of these capsule types is known in particular from the patent literature (see e.g. EP-A-26914).
- the 15 customarily used compounds which develop color in contact with an acid are suitable as color formers for the printing inks according to the invention.
- Examples include triphenylmethanes, diphenylmethanes, xanthenes, in particular fluoranes and rhodamine lactams, thiazines and spiropyrans, which can be used individually or in the form of mixtures.
- core oils used as solvents for the color former also correspond to the prior art.
- examples include chlorinated diphenyl, chlorinated paraffin, cottonseed oil, peanut oil, silicone oil, phthalate esters, phosphate esters, sulfonate esters, monochlorobenzene, partially hydrogenated terphenyls, alkylated diphenyls, alkylated naphthalenes, aryl ethers, aryl alkyl ethers and higher alkylated benzene.
- Binders contained according to the invention are rosin derivatives, essentially alkali salts of abietic acid, potassium, lithium and in particular sodium being mentioned as alkali. These binders are soluble in the glycols and glycol ethers used as solvents. Individual solvents are, for example, ethylene glycol, 1,2-propylene glycol, glycerol, diethylene glycol, dipropylene glycol, polyglycols with a molecular weight of 200 to 600, ethylene glycol monomethyl, ethyl or butyl ether or monoethers of polyglycols. Mixtures of these solvents are also suitable. Low-viscosity solvents, such as. B. glycerol or propylene glycol.
- the printing inks according to the invention are e.g. B. composed as follows:
- microcapsules are preferably used in a dry form, since this makes it easier to achieve the concentration required for later generation of the typeface.
- the printing inks according to the invention are obtained by mixing the components, it is expedient first to dissolve the binder in the solvent and then to stir the microcapsules in the solution.
- a spacer to the printing ink in 10 quantities up to 15% by weight, preferably 5-10%, based on the printing ink.
- Spacers of this type are also known from the patent literature, for example titanium dioxide, plastic spheres with diameters of 20-30 ⁇ m, cellulose fibers or calibrated starch.
- the printing inks are particularly suitable for spot printing.
- microcapsule powder 35 parts by weight of microcapsule powder (microcapsules prepared in accordance with EP-B-26 914, containing a 30 color former / black mixture)
- calibrated starch e.g. Amyzet ® KT
- microcapsule powder 20 30 parts by weight of microcapsule powder, containing a blue-writing color mixture, 5 parts by weight of cellulose flour (Arbozell ® B600 / 30 der
