Abstract
A process for forming color images which comprises providing a light absorbing dye layer or a dye containing layer on a base, at least the surface of which is composed of a transparent dye accepting polymer through which dyes are capable of thermally diffusing, imagewise exposing the dye layer or the dye containing layer to light having a high energy density such that a dye image is formed in the dye accepting polymer in the exposed area by thermal diffusion of the dye, and thereafter removing the dye or the dye containing layer in the unexposed areas.
