1. A substrate pretreatment material comprising;
- a) from 0.1 to 50 weight percent of an azetidinium functionalized polymer,b) from about 0.1 to 50 weight percent of an at least partially quaternized copolymer of sulfur dioxide and allylamine and/or diallylamine of weight average molecular weight from about 3,000 to 200,000 g/mole, wherein allylamine includes mono, di, and trialkyl (C1-C6) substituted allylamine and diallylamine includes mono and dialkyl (C1-C6) substituted diallylamine,c) optionally a surface tension modifier selected from the group of mono or polyhydroxy C1-C10 alcohol, an alkylene oxide oligomer of less than 500 g/mole molecular weight, or a surfactant, wherein said weight percent are based on 100 parts by weight of substrate pretreatment.

Abstract
An aqueous blend of an azetidinium functionalized polymer and a polymer having quaternary amine groups is disclosed for use as aqueous pretreatment for substrates such as textiles and garments that are going to be digitally printed. The pretreatment may further comprise wetting agents, surfactants, and preservatives. The pretreatment may be dry or wet immediately prior to digital printing and may be heat treated to bond the pretreatment to the substrate and/or the subsequent print ink.
