Title:
DIFFUSION TRANSFER TYPE HEAT-DEVELOPABLE PHOTOSENSITIVE MATERIAL
Document Type and Number:
Japanese Patent JPH07168337
Kind Code:
A
Abstract:

PURPOSE: To obtain the photosensitive material capable of forming a dye transfer image reduced in fog during storage and small in restraint of silver development reaction and high in maximum density and low in minimum density.

CONSTITUTION: This heat-developable photosensitive material contains photosensitive silver halide and a reducing agent and the dye donor represented by formula I and a heterocyclic compound represented by formula II, and in formulae I and II, compound group to A is a 1,3-S-N-compound group to cause cleavage reaction and to release a combining group; each of J1, J2, X1, and X2 is a bonding group: each of a-e is an integer; Dye is a dye group or a dye precursor group; G is a nonmetallic atomic group necessary to form a monocyclic or condensed hetero ring together with the carbon atom; M is H or an alkali metal atom; the ring structure of formula II has -NH- or its hetero ring is substituted by -NHR1; and R1 is H or alkyl.
