Abstract
This invention provides an aqueous composition having a pH of from 4 to 10 which is smooth spreading and comprises a crosslinked copolymer comprising (meth)acrylic acid residues, alkyl(meth)acrylate residues, lipophilically modified (meth)acrylate residues, and crosslinker.
Claims11
An aqueous composition comprising from 0.1 to 8 weight percent of one or more crosslinked copolymers, wherein:
- a) each of the one or more crosslinked copolymers independently comprises from 2.5 to 35 weight percent (meth)acrylic acid residues, from 10 to 80 weight percent C2-C4 alkyl (meth)acrylate residues, from 2 to 25 weight percent lipophilically modified (meth)acrylate residues, and from 0.001 to 7.5 weight percent residues of a crosslinker wherein the crosslinker has no ester or amide functionality;
- and
- b) the pH of the composition is from 4 to 10;
- c) when applied to a substrate, the composition smoothly spreads to form a continuous film without breaking up forming lumps or rough sheets;
- and
- d) the composition contains from zero to less than 1 weight percent surfactant.
