PURPOSE:To improve peeling property of between a photosensitive element and a fixing element of a coloring matter, after heat-developing and transferring the coloring matter by incorporating a specific compd. to one of the photosensitive element and the fixing element of the coloring matter. CONSTITUTION:The compd. shown by the formula is incorporated at least one of the photosensitive element and the fixing element of the coloring matter to improve the peeling property, when both the developing and transferring are effected by heating the combination of the photosensitive element and the fixing element of the coloring matter in the presence of a very small amount of water and a base and/or a base precursor. The used amount of the prescribed compd. may be varied over a broad range, and is preferably 0.001-1.0g, more preferably, 0.01-0.5g, further more preferably, 0.03-0.3g per 1(m)<2> of a substrate. The used base precursor is that of capable of releasing or forming the base by a thermal decomposition or an electrolysis or a complex forming reaction, and is exemplified by an inorg. base or an org. base, etc. |
