RADIATION-CURABLE PRESSURE-SENSITIVE ADHESIVE HAVING IMPROVED ADHESION TO PLASTICIZED VINYL SUBSTRATES

摘要

The current invention provides a photopolymerized presssure-sensitive adhesive which adheres well to all common surfaces and has an outstanding ability to bond to plasticized vinyl substrates and to remain firmly bonded thereto even after remaining in contact therewith for extended periods of time comprising an acrylic copolymer and an ethylene vinylacetate copolymer or mixture of copolymers. Preferred pressure sensitive adhesives of the invention comprise from about 10 to about 30 parts of the ethylene vinylacetate copolymer or a mixture thereof.
