PURPOSE:To obtain a high-density image usable also as an intermediate original through low temp. development, by combining a specified binder and an amino acid. CONSTITUTION:A diazo compd. and other additives are dissolved in an ionomer resin soln., a dispersion liquid, or an emulsion liquid, or dispersed, applied onto a support, and dried to form the first layer having 0.2-15g/cm2 attached amt., and a coupling component, an ordinary binder resin, and other additives are dispersed or dissolved in a solvent not dissolving the first layer components, and this liquid is applied likewise to form the second layer, and a laminate photosensitive layer. At that time, a heat-meltable color forming aid having 50-150 deg.C m.p. and an amino acid are added to at least one of the first and second layers, or the diazo compd. and the coupling component may be exchanged to form the photosensitive layer.
