PURPOSE:To obtain a recording material with which the decoloration of an image by contact with a plasticizer, oil and water is extremely little by using an atom. amino compd. and photoradical generating agent as essential components and making one thereof exist in a dispersed state. CONSTITUTION:The arom. amino compd. forming a dye by a radical reaction is particularly preferably secondary and tertiary amine compds. has >=60 deg.C m.p., and is preferably solid at an ordinary temp. An org. halogenide compd. is more particularly preferable as said compd. exhibits high photosensitive by forming an electric charge transfer complex with the arom. amino compd. Such compd. is exemplified by carbon tetrachloride, carbon tetraiodide, dibrommethane, iodoform, bromoform, hexachlorobenzene, tetrachloroethylene, hexachloroethane, tribromomethane phenylsulfone, etc. These photoradical generating agents are preferably used at a ratio of 0.1-10pts.wt. by 1pt.wt. amino compd. |
