Abstract
1424643 Photographic, light-sensitive, heatdevelopable materials FUJI PHOTO FILM CO Ltd 14 Jan 1974 [17 Jan 1973] 01659/74 Heading G2C Photographic light-sensitive, heat-developable silver halide materials contain in one or more layers a) an organic silver salt e.g. silver behenate, b) a light-sensitive silver halide, or a compound which forms such silver halide by reaction with the organic silver salt, present in an amount to catalyze reduction of the organic silver salt by a reducing agent when the halide has been exposed to light, c) the reducing agent, d) an optional binder and e) at least one sensitizer of the Formula where p= 0 or 1, Ar<SP>1</SP> and Ar<SP>3</SP> are aryl, Ar<SP>3</SP> is arylene, and at least one of Ar<SP>1</SP>, Ar<SP>2</SP> and Ar<SP>3</SP> is substituted by -SO 3 M or -COOM, M being H, an alkali-metal or alkaline-earth metal or ammonium. Ar<SP>1</SP>, Ar<SP>2</SP> and Ar<SP>3</SP> may be further substituted and the material may have a top-coat polymer layer. The compounds (e) increase general sensitivity and some may optically sensitize.
