Abstract
Abstract A water reducible resin composition, a water reducible admixture of such resin with solvents and plasticizers, a water reduced form of such mixture suitable for a coating, and a coating prepared from such water reduced mixture. Said resin is required to be prepared from a balance of hydrophobic enhancing and hydrophilic enhancing monomers. Generally such hydrophobic enhancing monomers are required to be a balance of monomers promoting hard and soft segments of the resin.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
222 words
A resin, suitable for use in a water reducible composition having a Ring and Ball softening point in the range of about 100° C. to about 300° C. prepared by the method which comprises free radical aqueous emulsion polymerizing, in an aqueous medium having a pH in the range of about 2 to about 7, or free radical organic solution polymerizing a monomer method which comprises, based on 100 weight percent of monomers (A) about 60 to about 95 weight percent of at least one hard segment hydrophobic enhancing monomer selected from styrene, α-methyl styrene, acrylonitrile, vinyl toluene, methyl methacrylate, vinyl chloride and vinylidene chloride, (B) about 0 to about 35 weight percent of at least one soft segment hydrophobic enhancing monomer selected from at least one acrylate selected from methyl acrylate, ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, laural acrylate, isodecyl methacrylate, butyl methacrylate, isobutyl methacrylate, at least one vinyl ether selected from ethyl, butyl, octyl, decyl and cetyl vinyl ether and/or at least one diene selected from 1,3-butadiene, isoprene and 2,3-dimethyl butadiene, provided that said dienes of monomer part (B) and said monomer part (A) vinyl chloride and vinylidene chloride are not mixed together and copolymerized, and (C) about 3 to 15 weight percent of at least one hydrophilic enhancing organic acid selected from acrylic, methacrylic, fumaric, itaconic and maleic acid.
