ABSTRACT:
Disclosed is a method for forming an image in a recording material and transferring said image from said recording material to an image receiving material in order to produce a transferred image in said image receiving material, comprising the steps of: exposing said recording material, wherein said recording material comprises a support, a colorant layer containing a colorant, and a colorant barrier layer containing a light-absorbable substance in this order, said exposing causes to produce an ablated hole in said colorant barrier layer to form said image and said exposing is held with controlling means for exposing said recording material based on an image signal so that a size of said ablated hole in said colorant barrier layer is subject to change based on said image signal, said exposing means producing a light which is absorbed by said light-absorbable substance; and transferring said colorant from said colorant layer to said image receiving material through said ablated hole to produce said transferred image in said image receiving material in accordance with said image in said recording material by contacting said colorant barrier layer with an image receiving layer of said image receiving material in the presence of heat or pressure.
