Rapid printing etching-resistant ink

The invention provides a rapid printing etching-resistant ink. The rapid printing etching-resistant ink comprises, by weight, 30-60 parts of carboxyl modified epoxy acrylate, 7-30 parts of carboxyl modified polyester acrylate, 4-8 parts of saturated polyester resin, 20-40 parts of an acrylate monomer, 5-10 parts of a photoinitiator, 0.5-5 parts of an adhesion promoter, 0.5-2 parts of fumed silica,1-2 parts of a pigment and 0.1-1 part of a dispersing agent. The anti-etching ink is high in printing speed, and has the advantages of excellent anti-sticking effect, good acid etching resistance andadjustable alkali liquor film stripping speed. 本发明提供了一种快速印刷抗蚀刻油墨，所述快速印刷抗蚀刻油墨包括以下重量份数的各组分：羧基改性环氧丙烯酸酯30～60、羧基改性聚酯丙烯酸酯7～30、饱和聚酯树脂4～8、丙烯酸酯单体20～40、光引发剂5～10、附着力促进剂0.5～5、气相二氧化硅0.5～2、颜料1～2份、分散剂0.1～1份。上述抗蚀刻油墨印刷速度快，具有优异的抗反粘效果，耐酸蚀刻效果好，碱液褪膜速度可调的优点。
