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.
