PURPOSE:To stably obtain a fine polychromatic image with high color reproducibility and to prevent the lowering of sensitivity by incorporating a filler surface-treated with a compd. having an ethylenic unsatd. double bond into image forming elements. CONSTITUTION:A filler surface-treated with a compd. having an ethylenic unsatd. double bond is incorporated into image forming elements which are microcapsules obtd. by coating cores 1c, 1c' with shells 1d. Since the filler insoluble in a solvent acts as nuclei for crystallization in a solvent removing stage and many microcrystals are generated, even a material having high crystallizability solidifies without forming coarse crystals. The image forming elements are not made amorphous and have satisfactory independency, accordingly stable color reproduction is enabled over a wide transfer temp. range and sensitivity is improved. |
