A low viscosity energy curable epoxy resin composition essentially free of solvent for preparing an ink composition comprising: (a) at least one divinylarene dioxide compound, (b) at least one cycloaliphatic epoxy resin, (c) at least one vinyl ether compound, (d) at least one cationic photoinitiator, (e) at least one pigment, and (f) optionally, at least one oxetane; wherein (i) the viscosity of the curable composition is less than or equal to about 50 mPa·s at 25° C., (ii) the composition cures at a relative humidity of greater than 30%, and (iii) the composition cures with an increase in cure time of less than 100% when the composition is cured at a relative humidity of at least 70% compared to that of a composition that is cured at a relative humidity of less than or equal to 45%. The curable epoxy resin composition is useful, for example, for preparing an ink composition; and more specifically for preparing a solventless low viscosity UV curable inkjet ink composition.
一种基本不含溶剂的低粘度能量可固化环氧树脂组合物,用于制备油墨组合物,该组合物包含:(a) 至少一种二乙烯基二氧化物,(b) 至少一种环脂族环氧树脂,(c) 至少一种乙烯基醚化合物,(d) 至少一种阳离子光引发剂,(e) 至少一种颜料,以及(f) 可选地,至少一种氧杂环丁烷;其中(i) 该可固化组合物的粘度在 25° C 时小于或等于约 50 mPa-s。,(iii) 与在相对湿度小于或等于 45% 的条件下固化的组合物相比,在相对湿度至少 70% 的条件下固化的组合物的固化时间增加小于 100%。可固化环氧树脂组合物可用于制备墨水组合物,更具体地说,可用于制备无溶剂低粘度紫外线固化喷墨墨水组合物。
