<p>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: (x(CH2=CR1-C(O)O-)R2-(O-C(O)R3)y-O-C(O)-NH)n-R4, wherein R1 is hydrogen or methyl, R2 is an alkylene group or substituted alkylene group (typically having less than six carbon atoms, more typically two or three carbon atoms), R3 is an alkylene group or substituted alkylene group (typically having less than ten carbon atoms, more typically from four to six carbon atoms), R4 is the residue of an organic isocyanate (including trimerized isocyanates, but excluding isocyanate-functional prepolymers of active hydrogen compounds) having a functionality of n, n is an integer from two to four (typically two or three), x is an integer from one to three, and y is an integer from one to five, is provided. Also provided are printing inks comprising a colorant and a binder for said colorant comprising an aqueous emulsion polymer of this invention.</p> |
