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.

Abstract: A printing plate material for lithography showing superior balance of suitability for ink-jet printing and printability is provided. A printing plate material for lithography can include a support and an image-receiving layer containing a binder resin and a matting agent and provided on the support and can be constituted so that a hydrophilic resin having an average degree of polymerization of 2500 or higher is contained as the binder resin, and a matting agent showing an oil absorption of 350 ml/100 g or larger can be contained as the matting agent. It can also be constituted so that, as the binder resin, 60% by weight or more of the hydrophilic resin having an average degree of polymerization of 2500 or higher is contained based on the total binder resin. It can also be constituted so that, as the matting agent, 35 to 100 parts by weight of the matting agent showing an oil absorption of 350 ml/100 g or larger is contained for 100 parts by weight of the binder resin.
