(EN) ACRYLIC ADHESIVE COMPOSITION AND ADHESIVE PRODUCT
(FR) COMPOSITION D'ADHÉSIF ACRYLIQUE, ET ARTICLE ADHÉSIF
Abstract
(EN)
The present invention provides pressure-sensitive adhesive compositions which have excellent adhesion force, cohesion force, tack and holding power, and pressure-sensitive adhesive products including the pressure-sensitive adhesive compositions. The pressure-sensitive adhesive composition includes (i) 100 parts by mass of an acrylic block copolymer (I) including at least one polymer block (A) containing methacrylate ester units and at least one polymer block (B) containing acrylate ester units, the acrylic block copolymer (I) having a weight average molecular weight of 30,000 to 300,000, the acrylate ester units in the polymer block (B) including not less than 80 mass% of units from an acrylate ester (1) represented by the general formula (1): CH 2 =CH-COOR 2 (wherein R 2 is an organic group having 7 to 12 carbon atoms); (ii) 1 to 300 parts by mass of a tackifier resin; and (iii) 1 to 200 parts by mass of at least one plasticizer selected from process oils, and organic acid esters and oligomers thereof.

(FR)
L'invention fournit une composition d'adhésif excellente en ce qui concerne son adhérence, sa force de cohésion, ses propriétés collantes et sa résistance de collage, et un article adhésif mettant en œuvre cette composition d'adhésif. Cette composition d'adhésif pour (i) 100 parties en masse d'un copolymère séquencé acrylique (I) qui possède au moins une séquence polymère (A) constituée d'une unité ester d'acide méthacrylique, et au moins une séquence polymère (B) constituée d'une unité ester d'acide acrylique, dont la masse moléculaire moyenne en poids est comprise entre 30000 et 300000, et dans lequel 80% en masse ou plus de l'unité ester d'acide acrylique configurant ladite séquence polymère (B), sont constitués d'une unité ester d'acide acrylique (1) représentée par la formule générale (1) CH2=CH-COOR2 (dans la formule, R2 représente un groupe organique de 7 à 12 atomes de carbone), comprend (ii) 1 à 300 parties en masse d'une résine conférant une adhésion, et (iii) 1 à 200 parties en masse d'une huile de traitement ainsi que d'au moins une sorte de plastifiant choisie parmi un ester d'acide organique et un oligomère de celui-ci.
