ことを目的とする。For example, the process described in U.S. Pat. No. 2,714.066, the process described in U.S. Pat. 1.208.224 and U.S. Pat. No. 3.860.426. Then, on the support that has been treated in this way, an oleophilic image, which is usually used in photosensitive planographic printing plates, is formed.
A photosensitive composition is provided that forms an image having the property of repelling dampening water and accepting ink used during printing. This composition was disclosed in Japanese Patent Application Laid-Open No. 55-166645.
(1) A composition consisting of a diazo resin (2) A composition consisting of an 0-quinonediazide compound (
3) A composition consisting of a photosensitive azide compound (4) A composition consisting of a polymeric compound containing a -CH=CH-C- group in the main chain or side chain of the polymer (5) A composition consisting of an addition polymerizable unsaturated compound It is selected from among photopolymerizable compositions. However, although the photosensitive lithographic printing plate having the above-mentioned structure provides high image quality, it has the disadvantage of high cost. [Problems to be Solved by the Invention] Therefore, the present invention provides an inexpensive photosensitive material that can be used as a support for a lithographic printing plate without the need for the above-mentioned surface treatment, and in which various sheets other than aluminum sheets can be used. The purpose is to provide lithographic printing plates. A further object of the present invention is to provide an efficient method for manufacturing the inexpensive photosensitive lithographic printing plate.

Adhesives such as nylon, epoxy/nitrile rubber, epoxy/liquid nitrile, epoxy/pheno, phenol/polyvinylformal, α-cyano/acrylate monomer, and epoxy fine ceramics adhesives. used. Also used are titanate coupling agents, silane coupling agents, aluminum coupling agents, and the like. Among these, reactive adhesives are types that can firmly adhere solid powder by applying the adhesive onto a support, then applying a solid powder layer on the adhesive layer, and then solidifying the adhesive layer by heating etc. For example, epoxy adhesives are particularly preferred. Further, it is desirable that the adhesive has sufficient viscosity to coat the surface of the support so as to uniformly adhere the solid powder in a layered manner. The thickness of the coating film is preferably about 0.1μ to 5μ. Dip, air knife, curtain coating, hopper coating, and extrusion methods are used for these applications.
In some cases, it can also be applied by spray coating.

More specifically, one or a mixture of two or more of zinc oxide, aluminum oxide, silicon oxide, titanium oxide, and tin oxide are exemplified. but,
The present invention is not limited to these compounds, and any substance can be used as long as it has the above characteristics. In addition, the particles have an average particle size of 0.01~
100μ, preferably 0.01 to 50μ, more preferably 0.1 to 1μ. In the present invention, particles having the above characteristics are used because their surfaces are hydrophobic, so they have good adhesion with the adhesive layer and the photosensitive composition layer.
On the other hand, when processed with a developer, the p of the processing solution decreases.
This is because the surface of the particles is changed by H and becomes a hydrophilic compound, so that it can easily be converted into a hydrophilic layer, that is, an ink repellent layer.

In this case, solid particles can be dispersed in an organic solvent or water and applied in a layered manner. It is also possible to apply a very small amount, for example 10% by weight or less, of a binder, preferably a copolymer or hydrophilic polymer having hydrophilic and lipophilic units. Alternatively, a solid powder layer can be provided by uniformly applying an adhesive layer on the support, passing the solid powder through an air flow bath, and uniformly depositing the solid powder thereon, and then drying the adhesive layer.
