一种环保型LED光固化3D光变磁性油墨
摘要：
本发明公开了一种环保型LED光固化3D光变磁性油墨，包括按重量份数计的以下组份：LED光固化镜面树脂70-95份；导磁效应颜料1-25份；LED光固化透明色浆0-5份(可不添加)；优选的，所述LED光固化镜面树脂包括LED光固化树脂、光固化镜面树脂、单体、光引发剂、助剂，所述LED光固化树脂自环氧丙稀酸树脂、聚酯丙烯酸酯树脂、聚醚丙烯酸酯树脂、聚氨酯丙稀酸树脂中的一种或几种的混合物、所述光固化镜面树脂为光固化的纤维素树脂。本发明的磁性油墨为无溶剂油墨，清洁环保，使用LED光固化工艺，对印刷基材变形伤害少，没有臭气排放，且制作的图案立体感强，磁定型快，生产效率高。
摘要（英）：

The invention discloses an environmentally-friendly LED light-cured 3D photochromic magnetic ink. The magnetic ink comprises, by weight, 70-95 parts of LED light-cured mirror surface resin, 1-25 partsof a magnetic conductive effect pigment and 0-5 parts of an LED light-cured transparent color paste (or not added); and preferably, the LED light-cured mirror surface resin comprises LED light-curedresin, light-cured mirror surface resin, a monomer, a photoinitiator and an assistant, the LED light-cured resin is one or a mixture containing two or more of epoxy acrylic resin, polyester acrylate resin, polyether acrylate resin and polyurethane acylic resin, and the light-cured mirror surface resin is light-cured cellulose resin. The magnetic ink is a solvent-free ink, is clean and environmentally friendly, and an LED light-curing technology used in the invention has the advantages of few damages to the deformation of a printing substrate, no stink emission, strong stereo perception of a made pattern, fastness in magnetic sizing, and high production efficiency.
