ABSTRACT:
A method for recording a photographic image on an image-recording material is provided, wherein an image-recording material formed by coating at least a photographic silver halide, a polymerizable vinyl monomer, and a hydrazine derivative represented by formula (I) ##STR1## wherein X represents a hydrogen atom, an alkyl group, or a group represented by ##STR2## positioned in an ortho-, meta-, or para-position on the benzene ring; Y represents ##STR3## or --SO.sub.2 --; R.sub.1, R.sub.2, R.sub.3, and R.sub.4 each represents a hydrogen atom, an unsubstituted alkyl group, or a substituted alkyl group, provided that R.sub.1 represents a hydrogen atom only when Y represents ##STR4## on a support is imagewise exposed to form a latent image in said photographic silver halide and then heated so as to polymerize said polymerizable vinyl monomer in the part having said latent image to form a polymer image therein.
The present process does not require any wet treatment, and is capable of forming a polymer image simply by heating for a short period of time, and thus, may record a polymer image with a photo-sensitivity which is comparable to that of a conventional silver halide photographic material, with the use of only a small amount of silver halide.
