Abstract

1299217 Photo-sensitive diazotype materials GAF CORP 23 April 1970 [5 May 1969] 19526/70 Heading G2C A two-component diazotype material comprises a fibrous support coated with a composition containing a pigment, polyvinylpyrrolidone which may be substituted and which is 0À75-3% by weight of the composition, and a polyvinyl acetate emulsion and then coated with a 2-component diazotype composition containing an acid stabilizer. Specified pigments are silica and alumina. The light-sensitive layer may contain allylhyoxyethylthiourea.
