    • The present invention provides a coating composition which encompasses an aqueous dispersion of from about 2 to about 40 percent by dry weight, based on the dry weight of the coating composition, of a cationic polymer; and from about 60 to about 98 percent by dry weight, based on the dry weight of the coating composition, of a nonionic or cationic binder. The coating composition is thermally fusible and adapted to be receptive to ink jet inks and to retain the ink jet inks after being thermally fused. Alternatively, the coating composition may encompass an aqueous dispersion of a powdered thermoplastic polymer and from about 10 to about 150 dry parts by weight of a binder, based on 100 dry parts by weight of the powdered thermoplastic polymer. Desirably, the coating composition will encompass an aqueous dispersion of a powdered thermoplastic polymer; from about 2 to about 50 dry parts by weight, based on 100 dry parts by weight of the powdered thermoplastic polymer, of a cationic polymer; and from about 10 to about 150 dry parts by weight, based on 100 dry parts by weight of the powdered thermoplastic polymer, of a nonionic or cationic binder. The coating composition also may contain from about 1 to about 5 parts by weight, based on the weight of the coating composition, of a surfactant. When applied to a substrate, the coating composition permits printing on the substrate with ink jet inks to give a printed image which is durable, especially in the presence of water.
    • 本发明提供一种涂料组合物,其包含基于涂料组合物的干重约2至约40重量%的阳离子聚合物的水分散体; 和约60至约98%的干重,基于涂料组合物的干重,非离子或阳离子粘合剂。 涂料组合物是热熔性的并且适于接受喷墨油墨并且在热熔融之后保持喷墨油墨。 或者,涂料组合物可以包含粉末状热塑性聚合物的水性分散体和约10至约150干重份的粘合剂,基于100重量份粉末状热塑性聚合物。 期望地,涂料组合物将包含粉末状热塑性聚合物的水分散体; 约2至约50干重份,基于100重量份粉末状热塑性聚合物,阳离子聚合物; 和约10至约150干重份,基于100重量份粉末状热塑性聚合物,非离子或阳离子粘合剂。 涂料组合物还可以含有约1至约5重量份,基于涂料组合物的重量,表面活性剂。 当涂覆在基材上时,涂料组合物允许用喷墨油墨在基材上印刷,以得到耐久的印刷图像,特别是在水的存在下。
