Claim:
1. A hydrophobic alkali soluble emulsion comprising a polymer obtained by polymerizing the following monomer components: a) from 40 wt. % to 50 wt. %, based on the total weight of the polymer, of an α,β-ethylenically unsaturated carboxylic acid monomer; b) from 40 wt. % to 50 wt. %, based on the total weight of the polymer, of an α,β-ethylenically unsaturated nonionic monomer; c) from 5 wt. % to 8 wt %, based on the total weight of the polymer, of a nonionic macromonomer having the formula: wherein R is H or CH d) from 1 wt. % to 3 wt. %, based on the total weight of the polymer, of a methyl polyglycol acrylic acid ester.
