Title:
HEAT-DEVELOPABLE SILVER SALT PHOTOGRAPHIC SENSITIVE MATERIAL AND IMAGE FORMING METHOD
Document Type and Number:
Japanese Patent JP3671486
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a sensitive material solving problems on thermal fog, silver color tone and image preservation without lowering sensitivity.
SOLUTION: In this image forming method using a heat-developable silver salt photographic sensitive material contg. at least photosensitive silver halide, an org. silver salt and a reducing agent, a compd. forming a complex with an Ag ion exists in the sensitive material or other material and this compd. forms the complex for the 1st time at the time of heat development without forming the complex before heat development. The compd. preferably contains N and/or O and/or S. The sensitive material further contains a compd. represented by the formula PUG-L-COOAg (when PUG is a photographically useful group and L is a divalent aliphatic or arom. group).
