Abstract

445,845. Producing photo-mechanical printing surfaces. ROHLER, H., 47, Eisenbahnstrasse, Leipsic, Germany. July 17, 1934, No. 20930. Void [Abridged as open to inspection under Sect. 91 of the Acts, Jan. 18, 1935]. [Class 98 (ii)] Light-sensitive layers adapted for use as resists in the production of photo-mechanical printing-surfaces comprise solutions or emulsions of substances, rendered insoluble by exposure in the presence of chromates or the like, to which are added one or several solvents of different dissolving power, or one or several non-solvents. Albumen, gums, natural and artificial resins sensitized with chromic acid may be used. Saponification products of resins with inorganic or organic bases, esters of resins, or condensation products of resins with nitrogen compounds may be used. Non-sensitizable substances such as resins, waxes, balsams, fats, oils and fatty acids may be added. Saponified shellac and albumen may be sensitized with ammonium bichromate. The copy may be reversed by coating with colour, asphalt or varnish and dissolving the negative image.
