Patent ID: 11168233

Abstract:
The present invention provides a curable composition, a pressure-sensitive adhesive, an adhesive tape and an adherend product, and belongs to the technical field of acrylate pressure-sensitive adhesives. The pressure-sensitive adhesive formed from the curable composition of the present invention features good resistance to resilience, especially resistance to resilience at high temperatures. The curable composition comprises: a monomer component, which comprises at least two polymerizable monomers, wherein the polymerizable monomers comprise a non-tertiary alcohol (meth)acrylate monomer and an acid functionalized non-ester unsaturated monomer with at least one ethylenically unsaturated group; a (meth)acrylate polymer tackifying resin with a weight-average molecular weight ranging from 10,000 to 60,000 Daltons and a glass transition temperature greater than or equal to 20° C.; and a non-(meth)acrylate polymer tackifying resin component, which comprises tackifying resins of at least two non-(meth)acrylate polymers, wherein the softening point temperature of tackifying resins of at least part of the non-(meth)acrylate polymers is greater than or equal to 130° C.
