PURPOSE:To obtain a multicolored image by a single process, by irradiating with three kinds of laser beams different in energy a base coated with a material comprising a uniform mixture of three kinds of microcapsules respectively enclosing leuco dyes capable of forming respectively cyan, magenta and yellow colors, developers, decolorizing agents and heat-fusible substances as core substances. CONSTITUTION:Microcapsules respectively for cyan, magenta and yellow colors are irradiated with three kinds of laser beams different in energy, under such an arrangement that the colors are formed respectively at temperatures T1, T2, T3 (T1<T2<T3) and that decolorizing agents 8, 11 are melted only at temperature of at least T2 and T3, respectively. For example, at the temperature T2, the leuco dye for magenta and a color developer for the dye react with each other to form the color, whereas the microcapsules for cyan undergo melting of the decolorizing agent 8, whereby the color-developed cyan dye is decolorized. Thus, the microcapsules for cyan, magenta and yellow independently form the colors at different temperatures, and a multicolor image can be recorded by a single process. |
