ADHESIVE COMPOSITION AND MASKING ARTICLE FOR PRODUCING PRECISE PAINT LINES

摘要

An adhesive article for masking a portion of a substrate surface from a liquid coating applied to the surface includes a support having first and second opposed major surfaces, and a cationic or zwitterionic adhesive composition disposed on at least a portion of at least one of the first and second opposed major surfaces. The adhesive composition provides a barrier that impedes the migration of the coating past the edge of the adhesive article.

主权项

1. An adhesive composition comprising a polymer, the polymer consisting essentially of the polymerized product of
a. about 0 wt % to 5 wt % based on the total weight of the polymer of acrylic acid, methacrylic acid, a carboxylate salt thereof, or a mixture of two or more thereof, wherein the amount of carboxylate salt is determined based on the weight of the corresponding free acid; b. about 50 wt % to 95 wt % based on the total weight of the polymer of an acrylate or methacrylate ester of an alcohol having between 8 and 12 carbons, or a mixture of two or more thereof; c. about 2 wt % to 45 wt % based on the total weight of the polymer of an acrylate or methacrylate ester having an alkylammonium functionality; d. about 0 wt % to 30 wt % based on the total weight of the polymer of vinyl acetate, isobutyl acrylate, N-vinyl pyrrolidone, or a mixture of two or more thereof; and e. about 0 wt % to 2 wt % based on the total weight of the polymer of a crosslinker.
