  • Publication number: 20050058936
    Abstract: The present invention provides an image recording material comprising a substrate, an intermediate layer, and a photosensitive layer containing a novolac phenol resin and a light to heat conversion agent and being recordable with an infrared laser. The intermediate layer and photosensitive layer are sequentially provided on the substrate. The intermediate layer contains a polymer having an acidic group and being capable of interacting with the novolac phenol resin contained in the photosensitive layer. A planographic printing plate excellent in chemical resistance and printing durability is obtained by heat-treating the image recording material at 150 to 300° C. after effecting image-wise exposure with an infrared laser and development.
