Rapidly absorbed printing inks and their use

The invention relates to water-dispersible binders for cationic electrocoating finishes, which binders are reaction products of (A) low molecular weight epoxide resins containing aromatic groups and having an epoxide equivalent weight of below 375, (B) aliphatic and/or alicyclic polyfunctional alcohols and/or carboxylic acids having a molecular weight of below 350, (C) if appropriate up to 60% by weight, relative to the total binder, of polyfunctional alcohols, carboxylic acids and/or SH compounds having a molecular weight of 500-5,000 and (D) primary, secondary and/or tertiary amines and/or salts thereof or a sulfide/acid mixture or a phosphine/acid mixture, the reaction product of A and B containing 10-45% of aromatic groups, calculated as the phenylene group. By means of the binders, a higher layer thickness is obtained in electrocoating.

A process for the preparation of multicoat coatings in which a pigmented aqueous basecoat composition is used which comprises a water-thinnable emulsion polymer as the film-former. The water-thinnable emulsion polymer is prepared in a two-stage emulsion polymerization. The first stage gives rise to a polymer having a glass transition temperature (T.sub.G1) of +30.degree. to +110.degree. C. In the second stage a mixture of monomers is polymerized in the presence of the polymer prepared in the first stage which by an exclusive polymerization gives rise to a polymer having a glass transition temperature (T.sub.G2) of -60.degree. to +20.degree. C. The hydroxyl value of the emulsion polymer is between 2 and 100.

The invention relates to water-dilutable binders for cationic electrocoating finishes. For the preparation of the binders, a di-epoxide compound, together with at least one mono-epoxide compound if desired, is converted by a polyaddition, carried out at 100.degree. to 195.degree. C. and initiated by a monofunctionally reacting initiator carrying either an alcoholic OH group, a phenolic OH group or an SH group, to form an epoxy resin which then subsequently is modified with

This application discloses a synthetic resin based on alcohol-modified polyepoxides. The synthetic resin can be prepared by reacting a diepoxide, or a mixture of diepoxides, having an epoxide equivalent weight of less than about 500, with compounds with a hydroxyl group, which is reactive towards epoxide groups, in a molar ratio from about 2:1 to about 7:6 at temperatures from about 100.degree. C. to about 180.degree. C. in an organic solvent free of hydroxyl groups. The synthetic resin has terminal epoxide gorups and a mean molecular weight from about 400 to about 5000.
