Abstract

PURPOSE: To raise the sensitivity of the photosensitive layer of a photosensitive sheet by adding colloidal silica to the layer to scatter light in the layer.
CONSTITUTION: A photosensitive layer containing 1 part by wt. of a naphthol or phenol derivative such as 4-methoxy-1-naphthol or 4-propoxyphnol, about 0.1W 0.5 part of a sensitizing dye such as eosine and about 1W100 parts of colloidal silica of about 1W100mμ grain size is laid on a support to form a photosensitive sheet. On other support a white pigment-containing precoat layer and an image forming layer based on a diazonium compound, an alkali forming agent and an acid stabilizer are laminated to form an image forming sheet, which is then combined with the above-mentioned photosensitive sheet to obtain a photosensitive and thermosensitive type copying material.
