    • A method of printing an ink that comprises reactive dyes as colorants. The ink has at least one cyclodextrin (CD) compound to react with reactive dye molecules, while a hydrophobic cavity is filled with a disperse dye component to create an encapsulation prior to the ink formulation stage. The ink also includes a crosslinking agent that is capable of creating a chemical bonding reaction between the unreacted portion of the hydroxyl functional groups of cyclodextrin (CD), an optional alkaline substance, and other optional ink additives. Permanently bonded color images are provided by the reaction between the chemically altered and colored cyclodextrin (CD) and the final substrate, which may be any cellulosic, protein, or polyamide fiber material, or mixtures with polyester, by the application of energy.
    • 一种印刷包含活性染料作为着色剂的油墨的方法。 油墨具有至少一种环糊精(CD)化合物以与活性染料分子反应,而疏水空腔填充有分散染料组分以在油墨配制阶段之前产生包封。 油墨还包括能够在环糊精(CD)的羟基官能团的未反应部分,任选的碱性物质和其它任选的油墨添加剂之间产生化学键合反应的交联剂。 通过化学改性和着色的环糊精(CD)和最终的底物(其可以是任何纤维素,蛋白质或聚酰胺纤维材料或与聚酯的混合物)通过施加能量的反应来提供永久粘合的彩色图像。
