Abstract:
1. A process for coating a solid substrate selected from the group consisting of paper, resin-coated paper, polymeric films, and flexible or inflexible woven fabric, comprising applying to one or both surfaces of the substrate a coating composition comprising an effective amount of at least one ink receptive surface coating composition or agent comprising a dye fixing compound of formula wherein, n and m are each independently an integer from 0–4, Q and Z are each independently a mono-carbocyclic or bicyclic-carbocyclic aromatic group which can be substituted by 1 to 5 members selected from the group consisting of hydrogen, hydroxyl, halo, alkoxy, alkyl, amino, carboxy, acetoxy, cyano and sulfhydryl, G is a bivalent C R R or a salt thereof, and the at least one ink receptive surface coating composition or agent also comprises from 5–95 wt. percent of a film forming binder; wherein the ink-receptive surface coating composition or agent of may also include at least one organic or inorganic cross-linker, wherein the term polymer refers to a compound having a molecular weight between 2,000 and 200,000, and wherein the salt of the basic nitrogenous moiety of the dye-fixing compound or polymer forms a quaternary ammonium salt, or forms a mixed metallic cation amine salt, with a counter ion selected from the group consisting of an organic or inorganic anion.
