ABSTRACT:
Copolymeric mordants coatable from water into copolymeric mordant layers for photographic products and processes are disclosed. The copolymeric mordants comprise polymerized repeating units from first and second polymerizable vinylbenzyl quaternary ammonium compounds (the first polymerizable compound, if homopolymerized, providing a water-soluble homopolymer and the second polymerizable compound being a micelle-forming compound which, if homopolymerized, forms a water-insoluble homopolymer). The copolymeric mordants are coatable to image-receiving layers for the mordanting of dyes in photographic products and processes.
