Abstract

907,718. Photolithographic printing-plate. LITHOPLATE Inc. Oct. 14, 1958 [Nov. 1, 1957], No. 32784/58. Class 98 (2). A support is treated with a polyfunctional amino-urea-aldehyde resin or a sulphonated urea-aldehyde resin in aqueous solution to result in an hydrophilic layer, and then with a light-sensitive diazo compound which becomes hydrophobic and insoluble on exposure. The support may be of paper, resin impregnated paper or, particularly, of metal and the resin therefor ureaformaldehyde reaction with an amine, polyamine or polyimine, or else reacted with an alkali metal sulphite. Descriptions of producing the resins are provided and amplified by references to foreign Specifications, and the diazo sensitizers are mainly disclosed by similar references. Eight examples describe production of the resin layers and treatment thereof with the condensation product of paraformaldehyde and p-diazo-diphenylamine sulphate as sensitizer.
