Patent ID: 7041338

Claim:
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 1 –C 12 straight or branched chain alkyl, alkenyl or alkynyl linking group which can be substituted in the carbon chain by 1 to 4 members selected from the group consisting of O, S, N atoms and 1–12 of the hydrogen atoms on the carbon chain may be replaced independently by a member selected from the group consisting of hydroxyl, halo, alkoxy, alkyl, amino, carboxy, acetoxy, cyano and sulfhydryl, R 3 and R 5 are each independently hydrogen or lower alkyl, and R 4 and R 6 are each independently hydrogen, alkyl, alkoxy or hydroxyl-substituted alkyl, 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.
