| 摘要 |
The present invention provides a hydrophobic alkali soluble emulsion comprising a polymer obtainable by polymerization with the following monomer components: a) from 40 wt. % to 50 wt. %, based on the total weight of the polymer, of an α,&bgr;-ethylenically unsaturated carboxylic acid monomer; b) from 40 wt. % to 50 wt. %, based on the total weight of the polymer, of an α,&bgr;-ethylenically unsaturated nonionic monomer; c) from 5 wt. % to 8 wt. %, based on the total weight of the polymer, of a nonionic macromonomer; and d) from 1 wt. % to 3 wt. %, based on the total weight of the polymer, of a methyl polyglycol acrylic acid ester. |
