目前国内软包装行业使用的溶剂型凹印油墨中含有大量有机溶剂,此外,在软包装凹印和加工过程中还需要加入一定量的稀释剂来调节油墨黏度和挥发速度,以适应印刷、复合工艺的要求。凹印油墨常用的稀释剂有甲苯、丁酮、异丙醇、二甲苯等。干式复合中酯溶性胶黏剂使用的溶 At present, solvent-based gravure inks used in the domestic flexible packaging industry contain a large amount of organic solvents. In addition, a certain amount of diluent needs to be added during the gravure printing and processing to adjust the viscosity and the volatilization speed of the ink so as to adapt to the printing and compounding processes Claim. Gravure commonly used ink diluent toluene, butanone, isopropanol, xylene and so on. Soluble compound used in dry compound ester soluble
