Abstract

501,069. Photo - mechanical printing- plates. HARRIS-SEYBOLD-POTTER CO. Aug. 26, 1937, No. 23452. Convention date, June 18. [Class 98 (ii)] In the preparation of lithographic printing- plates, the plate is coated with a solution containing a water-soluble halogenated polyvinyl alcohol. The sensitizing may be effected before or after coating. As sensitizers, ammonium chromate or bichromate or chromic acid may be used. Alternatively, organic chromates or bichromates, e.g. pyridine bichromate, urea-chromic acid and the reaction products of tetra-alkyl ammonium hydroxides or ethylene diamine with chromic acid may be used. Preferably the coating is applied in the presence of the same halogen as exists in the layer; for example by the use of a solution of the hypoacid in water. A water-soluble surface tension depressant, e.g. propyl or butyl alcohol, may be added to the coating' solution. Development may be effected with water, with alkylaryl ketones e.g. diphenyl heptadecyl ketone or with fatty acid amides, e.g. stearyl amide, and dissolution of the unhardened coating may be performed with #-glucono-lactone or gluconic acid. Heating of the plate to resinify the coating may be carried out 'after development. For example, zinc or aluminium plates may be heated for 15-30 minutes at 100 to 130‹ C.
