Abstract

A plate for use in lithographic printing is produced by depositing on a base a coat of a polyfunctional amino-urea-aldehyde resin and/or a sulphonated urea-aldehyde resin and interpolymerizing therewith a second coat of a water soluble monomeric acrylic compound. The base may be of aluminium, zinc, tin, magnesium, lead, chromium, copper or iron and may be oxidized, e.g. by heating, treatment with chromic acid, or anodizing, before coating. Foils, films and paper which may be impregnated with a phenol-formaldehyde resin may also be coated. Suitable acrylic compounds are acrylic acid, methacrylic acid, the ammonium, sodium and potassium salts thereof, acrylamide and methacrylamide.ALSO:A plate for use in lithographic printing is produced by depositing on a base a coat of a polyfunctional amino-urea-aldehyde resin and/or a sulphonated urea-aldehyde resin and interpolymerizing therewith a second coat of a water soluble monomeric acrylic compound. Suitable acrylic compounds are acrylic acid, methacrylic acid, the ammonium, sodium and potassium salts thereof, acrylamide and methacrylamide. The amino-urea-aldehyde resin may be made from 2 or 3 mols. of formaldehyde per mol. of urea and from 2 to 80, preferably 6 to 15% of a polyfunctional amine such as ethylene diamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine; the condensation products of polyamines leading to amine polymers such as tetraethylenepentamine and epichlorohydrin or tetraethylenepentamine and formaldehyde; the guanidines, the biguanides, the guanylureas and the salts thereof; and the hydroxylamines such as monoethanolamine, diethanolamine, and the like.
