  • Patent number: 7306893
    Abstract: An image recording material of the present invention comprises an anodized aluminum support, an intermediate layer containing a polymer having a carboxylic acid group in a side chain thereof and formed on the aluminum support, and a photosensitive layer containing at least 50% by weight or more of novolak type phenol resin and a photothermal conversion agent and recordable by IR laser beam. A planographic printing plate excellent in printing durability can be obtained by subjecting the image recording material imagewise to IR laser exposure treatment and to development treatment, and then heating the image recording material at 150 to 300° C.

  • 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.
