Abstract

907,289. Photo-lithographic printing-plate. LITHOPLATE Inc. Oct. 14, 1958 [Nov. 1, 1957], No. 32782/58. Class 98 (2). A support is treated with a modified melamine-aldehyde resin in aqueous dispersion or solution to result in a 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, the resin therefor of alkylated methylol melamine-formaldehyde wherein methyl or ethyl alcohol is used for etherification, or polyalkylenepolyamine - melamine - formaldehyde for which modification a number of short and long chain polyamines and polyimines are quoted. Descriptions of producing the resins are provided and amplified by references to foreign Specifications concerning such, 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-diezo-diphenylamine sulphate as sensitizer.
