Abstract:
The mechanical properties of gelatin layers are improved by the addition of a graft polymer of a cationic or anionic polyurethane, with polymerizable vinyl compounds.
Abstract:
The antistatic properties of photographic materials can be improved by applying an antistatic layer containing as antistatic agents a mixture of polymers, or a graft polymer, containing sulfo as well as carboxyl groups.
Abstract:
ANTIHALATION AND FILTER DYES CAN ADVANTAGEOUSLY BE MORDANTED IN PHOTOGRAPHIC LAYERS BY MEANS OF MORDANTING POLYMER COMPOUNDS WHICH ARE CONDENSATION PRODUCTS OF AMINOGUANIDINE AND HOMO OR COPOLYMERS OF STYRENE DERIVATIVES CONTAINING KETO GROUPS.
