Abstract

Dry copying material has a layer contg. a reducible, light insensitive silver salt, and a reducing bisphenol of formula:- (where R1 is alkyl or cycloalkyl; R2 is alkyl, cycloalkyl, aralkyl, or phenyl; R3 is H, alkyl, or cycloalkyl; and X is S or cycloalkyl; and X is S or CR4R5; R4 and R5 are H or alkyl). Has a good stability during prodn. and storage.
