Title
(EN) LAMINATE HAVING STRUCTURE INCLUDING THROUGH-HOLE
(FR) STRATIFIÉ AYANT UNE STRUCTURE COMPRENANT UN TROU TRAVERSANT
(JA) 貫通孔を含む構造体を有する積層体
Abstract
(EN)
Provided is a laminate which can achieve both of easiness of handling and adhesiveness in temporary fixing or the like, can be prevented from the transfer of adhesive residue, has excellent adhesiveness to various objects, particularly metals, and has a structure including a base part and a through-hole. A laminate comprising a base material and a structure that is provided on at least one surface of the base material and includes a base part and a through-hole, wherein the base part in the structure comprises an acrylic triblock copolymer (I), and the acrylic triblock copolymer (I) comprises two polymer blocks (A1) and (A2) each composed of a methacrylic acid ester unit and one polymer block (B) containing an acrylic acid ester unit represented by general formula: CH2=CH-COOR1 (1) (wherein R1 represents an organic group having 1 to 3 carbon atoms), has a (A1)-(B)-(A2) block structure, and has a weight average molecular weight of 50,000 to 250,000, and the total content of the polymer blocks (A1) and (A2) in the acrylic triblock copolymer (I) is 35% by mass or less.
