Abstract:
1. A method for imparting resistance to staining of a substrate which comprises applying to a substrate a stain resist composition comprising a hyperbranched polymer comprising polymer units derived from (a) maleic anhydride and (b) at least one terminally-unsaturated, acyclic aliphatic diene having at least 7 carbon atoms; wherein said polymer has at least one pendent olefinic group for each 10 polymer units, and wherein the maleic anhydride and the diene are in the polymer backbone and further wherein the diene is selected from the group consisting of 1,7-octadiene, 1,9-decadiene, 1,11-dodecadiene, 1,13-tetradecadiene and mixtures of two or more thereof.
