Articles coated with pressure-sensitive interpolymers containing 2- acrylamido-2-methylpropanesulfonic acid

摘要

Acrylic pressure-sensitive resins comprising at least one ester of acrylic acid or methacrylic acid containing from 6 to 20 carbon atoms and between 0.1 and 1.5 weight percent of 2-acrylamido-2- methylpropanesulfonic acid. The resins are prepared in aqueous emulsion and when coated on substrates and dried provide pressure-sensitive films with superior peel strength retention.
