摘　　要：目的研究醇溶性树脂对不同基材的附着牢度及以醇溶性树脂为连接料的油墨性能。方法以苯乙烯为硬单体,丙烯酸异辛酯为软单体,丙烯酸及氮羟甲基丙烯酰胺为功能单体,乙醇为溶剂,合成醇溶性苯乙烯-丙烯酸树脂,以合成树脂为连接料,添加分散剂、炭黑及酞菁蓝,研磨制得PE,BOPP,NY薄膜,用黑色、蓝色凹印里印油墨。结果合成树脂对PE,BOPP,NY薄膜的附着牢度良好,且油墨黏度随树脂用量的增加而增大。结论由质量分数分别为50%,15%,2%和33%的醇溶性树脂、颜料、分散剂、溶剂组成的塑料里印油墨的着色力、细度、黏度、附着牢度、初干性、溶剂残留总量和耐水煮性均符合食品包装要求。This work aimed to study the adhesion of alcohol soluble resin to different materials and the properties of the inks using alcohol soluble resin as the main ingredient. A alcohol soluble resin was synthesized with styrene and 2-ethylhexyl acrylate as the hard and soft polymeric monomers,respectively,acrylic acid and N-methylol acrylamide as the functional monomers,and ethanol as the solvent. Black and blue gravure everse inks were prepared using alcohol soluble resin as the main ingredient and the dispersing agent,carbon black and phthalocyanine blue as additives. The adhesion of resin to PE,BOPP and NY film was excellent,and the viscosity of ink increased with increasing amount of resin. When the content of alcohol soluble resin was 50% of the total mass,the pigment was 15%,the dispersing agent was 2% and the solvent was 33%,the properties of the ink including the color strength,fineness,viscosity,adhesion,initial dryness,residual solvent and boil water resistance could all meet the requirements of food packaging.
