摘要：A sensitization by amine was observed for the peel apart imaging system based on decarboxylation reaction which has been reported in a previous paper. In this system, an image was obtained by the modification of adhesive force at the flash illuminated boundary between the photo-thermal sensitive polymer layer and the plastic film owing to evolved gaseous carbon dioxide in exposed areas.It was found that the photographic speed was incresed by adding amine (about 1 molecular part to 4 molecular part carboxylic acid) to the photo-thermal sensitive layer. For example, the photosensitivity of an imaging sensor consisting of acetonedicarboxylic acid and 1, 3-diphenyl guanidine was 0.56 cm²/J. Whereas without amine it was 0.36 cm²/J.Furthermore it was observed that the decomposition temperature of the mixture of organic carboxylic acid with amine decreased with decrease in pKb of the mixed amine. Therefore amine is considered to accelerate the decarboxylation reaction in this system.
