A non-Newtonian photo-curable ink composition that comprises a structured network forming agent in an amount ranging from about 0.1 wt % to about 20 wt % by total weight of the ink composition; a salt in an amount ranging from about 0.05 wt % to about 20 wt % by total weight of the ink composition; an organic solvent; a photo-initiator; and a polymerizable material; wherein the ink composition has a first dynamic viscosity ranging from 25 cps to 10,000 cps at a first state and a second dynamic viscosity ranging from 1 cps to 50 cps at a second state. Also described herein is a method for making such non-Newtonian photo-curable ink composition and a method for producing printed images using such non-Newtonian photo-curable ink composition.
一种非牛顿型光固化油墨组合物,它包括一种结构化网络形成剂,其用量为油墨组合物总重量的约 0.1 wt % 至约 20 wt %;一种盐,其用量为油墨组合物总重量的约 0.05 wt % 至约 20 wt % (按油墨组合物总重量计)的盐;有机溶剂;光
引发剂;以及可聚合材料;其中油墨组合物在第一状态下具有 25 cps 至 10,000 cps 的第一动态粘度,在第二状态下具有 1 cps 至 50 cps 的第二动态粘度。本文还描述了制造这种非牛顿光固化油墨组合物的方法和使用这种非牛顿光固化油墨组合物生产印刷图像的方法。
