Photopolymerizable composition and recording material

摘要

A photopolymerizable composition that is highly sensitive not only to ultraviolet light, but also light in the range from visible light to infrared light, and a recording material containing the photopolymerizable composition, which is excellent in sensitivity and decolorization property in the background part, and which is capable of forming sharp images with high contrast. The photopolymerizable composition contains a polymerizable compound having an ethylenic unsaturated bond and a radical generator capable of forming a radical by the action of the compound and the radical generator upon each other.
