Beschreibung
Zusammenfassung:	The invention relates to the field of ink jet printing, and discloses polyvinyl alcohol ester sulfonate, a synthetic method thereof, a hydrophilic plate for printing and application thereof, and a printing plate. The polyvinyl alcohol ester sulfonate contains a chemical structure represented as the formula (1), wherein the sum of m and n is a positive integer of 400 to 5000; n/(m+n) is 0.05 to 1;x is a positive integer of 1 to 3; A1-A4 are independently hydrogen or C1-C6 alkyl groups; M is Li, Na, K or NH4. The hydrophilic high-molecular compound can greatly improve hydrophilicity of a coating layer and improve printability of the hydrophilic plate. 本发明涉及喷墨印刷领域，公开了种聚乙烯醇酯磺酸盐及其合成方法、印刷用亲水版和应用以及印刷版。该聚乙烯醇酯磺酸盐含有式(1)所示的化学结构，其中，m+n＝400～5000的正整数，n/(m+n)＝0.05～1，x为1～3的正整数；A～A各自独立地为氢或C～C的烷基；M为Li、Na、K或NH。该类亲水高分子化合物可大幅提升涂层的亲水性，改善亲水版的印刷适性。
