Abstract
The present invention relates to a polymer particle having a wax phase and a second phase. The wax phase includes a wax having a melting point of greater than 30° C. and comprising greater than 80% by weight of the wax phase. The second phase, free of ionic charge groups, includes a mono-alpha, beta-ethylenically unsaturated monomer free of ionic charge groups capable of addition polymerization to form a water soluble homopolymer including from 1 to 40% by weight of the second phase and a mono-alpha, beta-ethylenically unsaturated monomer capable of addition polymerization to form a water insoluble homopolymer.
