PURPOSE:To obtain the multicolor image using light and heat by means of a simple process by coating a coating solution which uniformly disperses a diazonium compd. capable of decomposing by reacting with each colored rays of a cyan, a magenta and a yellow colored rays, a coupler compd. capable of coloring by reacting with the diazonium compd. and a basic substance a coloring layer. CONSTITUTION:The coloring layer is obtd. by coating the coating solution which uniformly disperses the diazonium compd., the coupler compd. and the basic substance in a heat fusible substance. The diazonium compds. capable of reacting with each rays of the cyan, the magenta and the yellow color rays are decomposed and loses coloring ability by irradiating each rays having wavelengths of lambda1-lambda3, complying with the signals of three primary colors from CRT, etc., thereby forming a latent image. When the exposed coloring sheet is heated, the unsensitized diazonium compd. colors by reacting with the coupler compd. and the basic substance in a solvent, thereby forming the multicolor image. |
