Abstract
Abstract WHEREIN R is a lower alkyl radical having from 1 to about 3 carbon atoms, hydroxymethyl radical or the radical -CH2-OOC-R1 and R1 is an alkyl radical having from 1 to about 25 carbon atoms, the weight ratio of acrylic monomer to oxazoline in said copolymer being in the range of from about 75:25 to about 95:5, and drying the textile. A process for binding pigment to textiles, for example, cotton fabrics, by applying to the textile a liquid application medium having dispersed therein a pigment and a copolymer of an acrylic monomer of the formula WHEREIN R is hydrogen or methyl and R1 is hydrogen or an alkyl radical having from 1 up to about 6 carbon atoms and an oxazoline of the formula
