Title
(EN) Acrylic adhesive composition and adhesive product
(ZH) 丙烯酸系粘合剂组合物和粘合制品
Abstract
(EN)
Provided are an adhesive composition that has excellent adhesive force, cohesive force, tack, and holding strength and an adhesive article that uses the adhesive composition. The adhesive composition contains: (i) an acrylic block copolymer (I) that includes at least one polymer block (A) comprising a methacrylic acid ester unit and at least one polymer block (B) comprising an acrylic acid ester unit, that has a weight-average molecular weight of 30,000-300,000, and in which 80 mass% or more of the acrylic acid ester unit that constitutes the polymer block (B) is the acrylic acid ester (1) unit represented by formula (1), namely, CH2=CH-COOR2 (in the formula, R2 represents an organic group having 7-12 carbon atoms); and, relative to 100 parts by mass of the acrylic block copolymer (I), (ii) 1-300 parts by mass of a tackifier resin and (iii) 1-200 parts by mass of at least one plasticizer selected from among process oils, organic acid esters, and oligomers thereof.
