Title:
Ultraviolet curable (meth) acrylate pressure-sensitive adhesive composition and its manufacturing process
Document Type and Number:
Japanese Patent JP6336114
Kind Code:
B2
Abstract:
(Meth)acrylate pressure-sensitive adhesives, curable adhesive compositions that can be used to prepare the (meth)acrylate pressure-sensitive adhesives, and methods of making the (meth)acrylate pressure-sensitive adhesives are provided. More particularly, the (meth)acrylate pressure-sensitive adhesives contain (a) a meth(acrylate copolymer having a weight average molecular weight greater than 500,000 grams/mole (Daltons) and (b) a (meth)acrylate tackifier that has a weight average molecular weight greater than 20,000 grams/mole (Daltons) but no greater than 200,000 grams/mole (Daltons). The pressure-sensitive adhesives advantageously are prepared by ultraviolet (UV) curing a curable adhesive composition that contains minimal or no organic solvents.
