PURPOSE:To enhance the photosensitivity of a photosensitive heat-sensitive composition based on a cobalt complex, a photoreducing agent and a hydrogen donor etc. by adding a specified amount of water to the composition. CONSTITUTION:2-10wt% Water is added to a photosensitive heat-sensitive composition based on a cobalt (III) complex such as hexamminecobalt (III) perchlorate or hexamminecobalt (III) acetate, a photoreducing agent such as quinone, disulfide, diazonium salt or aromatic ketone and a hydrogen donor such as polyethylene glycol, nitrotriacetonitrile or polyvinyl acetal for converting the photoreducing agent into a reducing agent. |
