野では非常に価値のあるものである。(b) Problems to be solved by the prior art and the invention Conventionally, plate making for lithographic printing plates using electrophotographic copying machines involves copying originals onto master paper for direct printing (printing plate material) whose surface has been treated to make it hydrophilic. It is done by doing. Copying of original documents is performed by forming an oleophilic developed powder image on a drum or the like, and then transferring this developed powder image to a master paper for direct printing. This plate making using an electrophotographic copying machine is a simple plate making method using a copying machine that has become popular in recent years, so it is very suitable for the field of so-called light printing where the reproducibility of the original is not strictly considered and the number of copies printed is relatively small. is of value.

面が溶け出して印刷汚れを惹起する恐れがある。 The quantitative ratio of each component in the composition according to the present invention is approximately 50 to 200 parts by weight, preferably 80 to 180 parts by weight, of polyvinyl alcohol per 100 parts by weight of the water-soluble melamine resin. If the amount of polyvinyl alcohol is less than 50 parts by weight, the surface layer tends to lack hydrophilicity, and if it exceeds 20 parts by weight, the surface may melt and cause printing stains.

Preferably it is about 4 to 7 parts by weight. If the amount of the metal compound is less than 2 parts by weight, the insolubilization of polyvinyl alcohol tends to be incomplete, and if it exceeds 10 parts by weight, when the composition according to the present invention is used as a surface layer of a support, non-image areas may be The surface of the formed support lacks hydration and accepts printing ink, which tends to cause so-called scumming on the plate surface. Further, the amount of the curing catalyst for the water-soluble melamine resin may be an amount sufficient to cure the water-soluble melamine resin, and is, for example, 0.1 to 5 parts by weight per 100 parts by weight of the water-soluble melamine resin.

ある。 The amount of water-insoluble inorganic powder is the amount of water-soluble melamine resin
The amount is about 30 to 150 parts by weight, preferably about 50 to 120 parts by weight, per 100 parts by weight. If the amount of the water-insoluble water-soluble inorganic powder is less than 30 parts by weight, the unevenness of the surface of the support tends to vary, and the adhesion to the developing powder tends to vary as well. Further, even if the amount exceeds 150 parts by weight, the degree of unevenness on the surface of the support does not change much, and adding more than that tends to be uneconomical.

If the amount of metal phthalocyanine is less than 10 parts by weight, the ability to adsorb developing powder on the surface of the support tends to decrease, and if it exceeds 80 parts by weight, the ability to adsorb developing powder tends not to increase, making it uneconomical.
