Textile printing

Abstract

A textile printing material set includes a fabric substrate and an aqueous ink composition. The aqueous ink composition includes an aqueous ink vehicle, pigment, and from 2 wt % to 15 wt % of acrylic core-shell latex particles having an acrylic core copolymer with a glass transition temperature from −50° C. to 30° C. and an acrylic shell copolymer having a glass transition temperature from 50° C. to 130° C. The acrylic core copolymer and the acrylic shell copolymer of the acrylic core-shell latex particles in this example are present at an average weight ratio from 1:1 to 9:1.
