An aqueous polymer emulsion composition comprising a polymer having repeating units derived from at least one monomer selected from the group consisting of alkyl acrylates and alkyl methacrylates and at least one monomer having the formula: R<1>O-(C(R<2>)CH2O)m-R<3>-[(OCH2C(R<4>)H)n(OC(O)C(R<5>)=CH2)]a, wherein: R<1> is an alkyl group having 1 to 6 carbon atoms, R<2> and R<4> are independently hydrogen, methyl or ethyl, R<3> is an aliphatic, aromatic or cycloaliphatic organic (preferably a hydrocarbon) radical having (e.g. from 2 to 20 carbon atoms) and a valence of "a" plus 1, R<5> is hydrogen or methyl, a is 1, 2, or 3, m is 0 to 6, and n is 0 to 6, provided that the sum of m plus n is from 1-6, is provided. Also provided are printing inks comprising a colorant and a binder for said colorant comprising an aqueous emulsion polymer of this invention. |
