ABSTRACT:
Disclosed is a light and heat sensitive recording material which permits recording using infrared laser light, requires no developing solution or the like, causes no unnecessary generation of waste, and is capable of forming completely dry, black-and-white monochrome or color, and clear images with high contrast. The light and heat sensitive recording material comprises a light and heat sensitive recording layer disposed on a support member, comprising the light and heat sensitive recording layer. It includes an electron donating colorless dye contained in heat-responsive microcapsules; and an electron accepting compound, a polymerizable monomer which is cured by irradiation with light, and an organic borate salt or an organic borate salt of a cationic coloring material which develops functions as a photo polymerizing initiator when irradiated with light which are arranged outside the heat responsive microcapsules.
