Patent ID: 7217500

Claim:
A color image-forming material comprising an image recording layer capable of drawing an image by infrared laser exposure, the color image-forming material forming a color image without passing through a development processing step after image recording, wherein said image recording layer comprises (A) an infrared absorbent, (B) a cyclic color-forming compound having a cyclic structure within the molecule and forming a dye by a ring opening, and (C) a dye stabilizer which is a compound interacting with said cyclic color-forming compound to stabilize the ring-opened dye body and cause color formation and which is released from the interaction upon laser exposure, wherein the dye stabilizer comprises: an ionic compound; or a compound with one or more acid groups selected from the following: i) low molecular weight compounds which have a phenolic OH group; ii) low molecular weight or polymer compounds which have a carboxylic acid group; iii) low molecular weight or polymer compounds which have a phosphoric acid group or a phosphonic acid group; or (iv) low molecular weight or polymer compounds which have a sulfonic acid group.
