| 摘要 |
The present invention features novel methods and compositions for coating textile substrates, wherein the coating compositions are composed of a coating agent selected from one of (a) an azetidinium polymer, (b) a guanidine polymer, (c) a mixture of an azetidinium polymer and a guanidine polymer, and (d) a copolymer of an azetidinium monomer and a guanidine monomer. Textile substrates coated with the compositions provide high quality printed images when printed with an ink containing a reactive dye having ionizable and/or nucleophilic groups capable of reacting with the coating agent in the textile coating composition. Images printed on a textile substrate coated with a coating composition of the invention are bleed-resistant, water-resistant (e.g., water-fast), detergent-resistant (e.g., detergent-fast), and/or are characterized by an enhanced chroma and hue.
