Abstract

PURPOSE:To eliminate the need for steam supply from the outside at the time of image erasing and make erasing easy by containing hydroscopic moisture-contained material in forming the reverse photochromic type recording material. CONSTITUTION:The intermediate layer composed of zeolite (analcite, hydrosodalite, etc.) about 1pt.wt. and a binder (hydroxyethyl cellulose, carboxy methyl cellulose, etc.) about 0.2-2pts.wt. is formed on a substrate such as of plastic film and the photosensitive layer composed of thiazine dyes (methylene blue, thionine blue J, etc.) about 1pt.wt. and a binder about 50-500pts.wt. is formed thereon to provide the captioned recording material. Erasing the images (colorless or pale color) having been formed on the abovementioned recording material (recovering the original color) simply necessitates heating the same at about 100 deg.C or more with a simple device like hot roller.
