Pressure-sensitive emulsion interpolymers containing 2-acrylamido- 2- methylpropanesulfonic acid and having glass transition temperatures in the range of -15amp;deg; to -75amp;deg;C

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.
