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.
