The ink set of this invention comprises at least two inks, one of which contains a pH sensitive polymer, a glycol ether, and preferably a self-dispersing pigment colorant. A second ink is provided which comprises incompatible inorganic or organic salts or has an appropriate pH. The polymer precipitates onto a medium upon contact with the second ink, thereby providing improved dry time as well as bleed and halo control.
本发明的油墨组至少包括两种油墨,其中一种含有对 pH 值敏感的聚合物、乙二醇醚,最好是自分散颜料着色剂。第二种油墨含有不相容的无机盐或有机盐,或具有适当的 pH 值。聚合物与第二种油墨接触后会沉淀在介质上,从而改善了干燥时间以及渗色和光晕控制。
