摘　　要：以醇溶性聚氨酯为油墨用连接料主体,通过添加分散剂、哑粉、环保颜料、溶剂等助剂,制得通用于PET薄膜、NY薄膜和BOPP薄膜的凹印复合黑、蓝、红和黄墨(用于BOPP薄膜的油墨需添加0.5%附着力增强剂),并对所制得油墨的颜色、着色力、细度、黏度、附着牢度、初干性、表面张力、溶剂残留总量和耐水煮等性能指标进行了测定和分析,发现该系列油墨配方简单,不含苯类和酮类,且溶剂残留总量低于1.0 mg/m2,符合食品包装要求,是安全环保的可水煮通用型凹印复合油墨新产品。Black, blue, red and yellow gravure ink products, popularly applied on PET, NY and BOPP films, were prepared using alcohol soluble polyurethane as the main ingredient and the dispersing agent, SiO2 powder, environment-friendly pigment and solvent as additives （ adding 0.5% adhesion enhancer in case of BOPP）. The color, color strength, fineness, viscosity, adhesion, initial dryness, surface tension, residual solvent and boil water resistant were measured and analyzed. It was concluded that the formulas is simple, contains no phenyl and ketonic solvent, their residual solvent are lower than 1.0 mg/m2 which can meet the requirement of food packaging ; it is a series of novel popular gravure ink with safety and environment friendly nature.
