ルコールは平均重合度５００〜３，０００ 。The polyvinyl alcohol used in the photosensitive emulsion of the present invention has an average degree of polymerization of 500 to 3,000.

未露光部のウォッシュアウト性が悪く、好ましくない。Those having a saponification degree of 78 to 98 molar ratio are preferred. When the average degree of polymerization is less than 500, the degree of insolubilization by the diazo compound is low, resulting in poor mechanical strength and water resistance (3,000
When it is high, such as 0 or more, the viscosity of the composition solution becomes extremely high, making it difficult to coat. Furthermore, it has low water solubility during development,
Washout properties of unexposed areas are poor, which is not preferable.

又、未露光部のウォッシュアウト性も良くない。Further, when polyvinyl alcohol having a saponification degree of 78 mol SJJ or less is used, the water solubility is low, and the resulting film is flexible and inferior in strength. On the other hand, the degree of saponification is 98
When the molar coefficient is higher than that, the reactivity with the diazo compound is low;
Also, the washout properties of unexposed areas are not good.

いため、耐刷性、耐水性に欠け、表面の平滑性が悪い。The blending composition of polyvinyl alcohol, HolJ vinyl acetate emulsion and diazo compound in the photosensitive emulsion of the present invention is preferably in the range of 70-30:30-70:2-12 parts by weight. Polyvinyl alcohol component is 70%
When the amount is more than 1 part by weight, the degree of insolubilization by the diazo compound is low, resulting in poor printing durability and water resistance, and poor surface smoothness.

ハレーションの影響を受けやすい欠点がある。On the other hand, if the polyvinyl alcohol component is less than 30 parts by weight, the solvent resistance of the coating film will be low, resulting in poor printing durability, and the unexposed areas will have poor washout properties, resulting in insufficient development. In addition, the diazo compound component is sufficiently insolubilized to increase mechanical strength, solvent resistance, and water resistance.
The higher the amount, the better; however, if it is less than 2 parts by weight, crosslinking will be insufficient and sharp lines will not be obtained, and if it is more than 12 parts by weight, the screen will not cut into the screen very much and it will be susceptible to halation on the screen.
