PURPOSE:To provide a heat developable photosensitive material which prevents the perspiration of a UV ray absorbent by incorporating the UV ray absorbent and org. fluoro compd. therein. CONSTITUTION:All known compds. which have absorption in a UV part, more particularly 250-400nm region and have preferably no absorption in a visible part are applicable for the UV ray absorbent to be used. A benzophenone compd., butadiene compd., etc., are effectively usable and a benzotriazole compd., benzophenone compd. and methine compd. are more particularly effective. The org. fluoro compd. is a compd. having at least one, more preferably >=3 fluorine atoms and at least one, more preferably >=3 carbon atoms in the molecule. The heat developable photosensitive material which prevents the perspiration of the UV ray absorbent is thus obtd. |
