PURPOSE:To record a high-quality multicolor image record small in surface fogging and continuous in gradation by laminating a color developing agent layer, such as paper, and a layer containing porous microcapsules enclosing dye precursors, a polymerizable monomer, and a photoplymerization initiator on a substrate. CONSTITUTION:The color developing agent layer obtained by dispersing the color developing agent into a binder 7, and the porous microcapsules layer obtained by synthesizing the microcapsules 5a - 5c enclosing the photopolymerization initiators 3a - 3c each having photosensitive wavelengths different from each other, the polymerizable monomer 4, the dye precursors 6a - 6c by the interface polymerization method and dispersing the porous microcapsules 5a - 5c into a binder are laminated on the substrate 11, such as paper, thus permitting a multicolor image record small in surface fogging and continuous in gradation to be obtainbed. |
