Abstract:
Provided is a lithographic printing plate material having an excellent balance between printing durability and ink-absorbing capability. The lithographic printing plate material has an image-receiving layer on a support, wherein the image-receiving layer contains acetoacetyl-modified polyvinyl alcohol as a resin component, and contains at least 0.4 parts by weight of acetylene glycol per 100 parts by weight of the resin component. The image-receiving layer preferably contains 100 to 300 parts by weight of particles having a mean particle size of 7 to 50 nm, per 100 parts by weight of the resin component. In addition, the support is formed using aluminum that has been subjected to anodic oxidation.
