Composition for textile printing

   
   

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.

La invención del presente ofrece métodos y las composiciones de la novela para los substratos de capa del textil, en donde las composiciones de capa se componen de un agente de capa seleccionado a partir del uno (a) de un polímero del azetidinium, (b) un polímero del guanidine, (c) una mezcla de un polímero del azetidinium y de un polímero del guanidine, y (d) un copolímero de un monomer del azetidinium y de un monomer del guanidine. Los substratos del textil cubrieron con las composiciones proveen de imágenes impresas de la alta calidad cuando estaban impresos una tinta que contenía un tinte reactivo que tenía grupos ionizables y/o nucleophilic capaces de reaccionar con el agente de capa en la composición de capa del textil. Las imágenes imprimieron en un substrato del textil cubierto con una composición de capa de la invención son sangrar-resistentes, hidrófugas (e.g., agua-ra'pido), detergente-resistentes (e.g., detergente-ra'pido), y/o son caracterizadas por un chroma y una tonalidad realzados.
