Pressure-sensitive adhesive or pressure-sensitive adhesive tape for foreign-matter removal

摘要

A pressure-sensitive adhesive or pressure-sensitive adhesive tape for removing a foreign matter present on the surface of an article from the article, the pressure-sensitive adhesive having the property of curing with an actinic energy source to have a three-dimensional network molecular structure, a modulus of elasticity (as measured in accordance with JIS K 7127) before the curing of lower than 1 kg/mm2 and a modulus of elasticity after the curing of 1 kg/mm2 or higher, and a degree of volumetric shrinkage through the curing of 2% or higher.
