摘要： A method for thermally forming images for plate making, which comprises forming an image for plate making by using a thermally processed image recording material comprising a silver salt of an organic acid, a reducing agent, a color image forming material and an organic binder on a support, wherein the image consists essentially of a developed silver image and a color forming dye image and the color forming dye image shows an absorbance for ultraviolet region higher than that for visible region and has a transmission density of 0.3 or more for the region of 360-450 nm. There are provided a thermally processed image recording material and method for thermally forming images that provide significant difference of ultraviolet absorption between image areas and non-image areas suitable for printing plate making.
