Patent ID: 6903156

Claim:
A light fast, aqueous, strippable coating composition comprising A) 40 to 90 wt. %, based on resin solids of A) and B), of an aqueous polyurethane-polyurea dispersion comprising the reaction product of a diisocyanate, a polyesterpolyol based on adipic acid, 1,6-hexanediol and neopentylglycol, and a 2,2-bis-(hydroxymethyl)-alkane-monocarboxylic acid, and B) 10 to 60 wt. %, based on resin solids of A) and B), of a polymer prepared from radically polymerizable monomers, wherein the percentages of A) and B) add up to 100, based on the weight of resin solids of A) and B) and wherein B) is prepared by emulsion polymerization in the presence of A) and a portion of the monomers in B) are grafted onto the polyurethane-polyurea in A).
