Abstract
A peelable coating composition capable of providing coating films with good peelability particularly after UV exposure and desirable mechanical properties.
Claims13
A peelable coating composition, comprising:
- (a) an aqueous dispersion of an acrylic (co)polymer, wherein the aqueous dispersion comprises a water-soluble nonionic cellulose ether stabilizer, and wherein the acrylic (co)polymer is substantially free of, as polymerized units, a monoethylenically unsaturated monomer containing acid-functionality;
- (b) an amphoteric surfactant having an isoelectric point at pH 3 to pH 8;
- (c) a dispersion of core-shell polymeric particles present in an amount of from 1% to 15% by solids weight, based on the total solids weight of the coating composition;
- wherein the polymeric particles comprise, when dry, at least one void;
- and
- (d) a light absorber, a light stabilizer, or mixtures thereof.

A peelable coating composition comprising:
- (a) an aqueous dispersion of an acrylic (co)polymer present in an amount of from 60% to 95% by solids weight, based on the total solids weight of the coating composition;
- wherein the dispersion comprises a water-soluble nonionic cellulose ether stabilizer, and wherein the acrylic (co)polymer is substantially free of polymerized units of a monoethylenically unsaturated monomer containing acid-functionality;
- (b) an amphoteric surfactant having an isoelectric point at pH 3 to pH 8;
- (c) a dispersion of core-shell polymeric particles present in an amount of from 1% to 15% by solids weight, based on the total solids weight of the coating composition;
- wherein the polymeric particles comprise, when dry, at least one void;
- and
- (d) from 0.1% to 10% by weight, based on the total solids weight of the coating composition, of a light absorber, a light stabilizer, or mixtures thereof.
