ADHESIVE, DOUBLE-SIDED ADHESIVE SHEET, OPTICAL FILTER AND DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide an adhesive for an electromagnetic shielding film that has dent resistance and initial reworkability combined with sealability of a mesh, to provide an optical filter using the adhesive and to provide a display.

SOLUTION: The adhesive is produced by crosslinking a main agent composed mainly of (A) a polymer with (B) a crosslinking agent. The polymer (A) has (a1) a structural unit based on a methyl acrylate, (a2) a structural unit based on a butyl acrylate and (a3) a structural unit having a functional group which reacts with an isocyanate group and has a molar composition ratio of the structural unit (a1) to the structural unit (a2) of 60/40 to 40/60, a weight average molecular weight Mw in the range of 350,000-550,000 and a ratio of the weight average molecular weight Mw to the number average molecular weight Mn of 6 or less. The crosslinking agent (B) is an adduct product or/and a biuret product of a hexamethylene diisocyanate.
