PURPOSE:To obtain a cheap nonsilver type recording material not requiring fixing by combining a photosensitive sheet using a phenol or naphthol derivative and an image receiving sheet using polyacid (derivative) of Mo and W. CONSTITUTION:1pt.wt. of a phenol or naphthol derivative such as 4-methoxyphenol or 4-propoxyphenol, about 100-1,000pts. of a binder such as ethyl cellulose, about 0.1-0.5pt. of a sensitizing dye such as eosine or erythrosine and about 2-20pts. of a sensitivity auxiliary are blended and coated onto a translucent or transparent support to form a photosensitive sheet having an about 2-10mu thick photosensitive layer. On the other hand, a mixture of 1pt.wt. of polyacid (derivative) of Mo and W such as phosphomolybdic acid and about 1-10pts. of a binder such as ethyl cellulose or gelatin is coated onto a support to form an image receiving sheet having an about 2-20mu thick coloring layer. This image receiving sheet is combined with the abovementioned photosensitive sheet to obtain a recording material. |
