PHOTOSENSITIVE HEAT-SENSITIVE RECORDING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a photosensitive heat-sensitive recording material with high whiteness of non-image areas (ground skin areas) even under high temperature environment and excellent green storing properties. SOLUTION: In the photosensitive heat-sensitive recording material provided with a photosensitive heat-sensitive recording layer containing a diazonium salt and a coupler on a substrate, the photosensitive heat-sensitive recording material is characterized by incorporating an acid generating agent slowly releasing an acidic compound with time in the photosensitive heat-sensitive recording layer.
