PURPOSE:To obtain the titled material capable of forming a prescribed clear image, even if in case of changing heating condition by heat developing the sensitive material in the presence of a tertiary amine simultaneously or after image wisely exposing it. CONSTITUTION:The titled material having the photosensitive layer contg. a silver halide, a reducing agent, a polymerizable compd. and the tertiary amine is heat-developed simultaneously or after image wisely exposing it. The tertiary amine is not specified, and comprises the tertiary amine and its salt. In a practical point of view, the tertiary amine which dissolves >=10% in a distilled water at 25 deg.C is preferable. In a functional point of view, the tertiary amine which has >=6.0pKa is more preferable. The used amount of the tertiary amine is 0.1-100mol, more preferably 0.5-10mol on the mol basis of 1mol the used reducing agent. |
