Abstract
A lithographic printing plate support comprising a substrate having thereon a porous layer comprising metal oxide particles bound by a compound containing a metal atom and a phosphorus atom.
Claims8
A lithographic printing plate support comprising a non-anodized substrate having thereon a porous layer comprising metal oxide particles bound by a reaction product between a phosphorus compound and a metal oxide, or a reaction product between a phosphorus compound and a reaction accelerator,
- wherein the substrate is an aluminum plate, an aluminum-laminated paper, an aluminum-laminated resin or an aluminum-coated metal.
A lithographic printing plate support comprising a non-anodized substrate having thereon an interlayer formed from a composition comprising high-porosity particles incorporated in a reaction product between an alumina particle, a phosphoric acid and an aluminum compound.
A method for producing a lithographic printing plate support comprising a non-anodized subsisate having thereon a porous layer and a pore-sealing layer in this order, which comprises surface-roughening the substrate, providing the porous layer comprising metal oxide particles bound by a reaction product between a phosphorous compound and a metal oxide, or a reaction product between a phosphorous compound and a reaction accelerator on the surface-roughened substrate, and providing the pore-sealing layer on the porous layer.
