PURPOSE: To obtain a photosensitive and heat sensitive type copying material providing increased image density by combining a photosensitive sheet with a precoat layer and an image receiving layer and adding water insoluble fatty acid amide to the precoat layer or the image receiving layer.
CONSTITUTION: A photosensitive and heat sensitive type copying material is obtd. by combining a photosensitive sheet formed by laying a photosensitive layer contg. a phenol deriv. or a naphthol deriv. and a sensitizing dye on a support with an image receiving sheet formed by laying a precoat layer consisting of a white pigment and a water soluble or emulsive natural or synthetic high molecular binder and an image receiving layer contg. a diazo compound, an acid stabilizer for the diazo compound and a thiourea deriv. on a support. At this time, to the precoat layer or the image receiving layer is added water insoluble fatty acid amide with 90W120°C m.p. represented by RCONH2 (where R is 5W 24C satd. or unsatd. alkyl).
