Abstract:
(EN) The thermosensitive pressure-sensitive adhesive according to the present invention comprises a base resin (A) having an SP value in the range of 18±2 and a side-chain-crystalline polymer (B) comprising constituent units of a monomer ingredient comprising a (meth)acrylic ester (B1) having a linear C14-30 alkyl group, wherein the side-chain-crystalline polymer (B) has an SP value satisfying relationship (I). The thermosensitive pressure-sensitive adhesive has reduced adhesive force at temperatures not lower than the melting point of the side-chain-crystalline polymer (B). {[SP value of (A)]-2}≤[SP value of (B)]≤{[SP value of (A)]+2} (I)
(FR) L'adhésif thermosensible sensible à la pression selon la présente invention comprend une résine de base (A) présentant une valeur SP dans la plage de 18±2 et un polymère cristallin à chaîne latérale (B) comprenant des motifs constitutifs d'un ingrédient monomère comprenant un ester (méth)acrylique (B1) présentant un groupe C14-30-alkyle linéaire, le polymère cristallin à chaîne latérale (B) présentant une relation satisfaisant à la valeur SP (I). L'adhésif thermosensible sensible à la pression présente une force d'adhérence réduite à des températures qui ne sont pas inférieures au point de fusion du polymère cristallin à chaîne latérale (B). {[Valeur SP de (A)]-2}≤[valeur SP de (B)]≤{[valeur SP de (A)]+2} (I)
(JA) 本発明に係る感温性粘着剤は、18±2のSP値を有するベース樹脂(A)と、炭素数14~30の直鎖状アルキル基を有する(メタ)アクリル酸エステル(B1)を含むモノマー成分を構成単位とする側鎖結晶性ポリマー(B)とを含有し、側鎖結晶性ポリマー(B)が、下記式(I)を満足するSP値を有し、側鎖結晶性ポリマー(B)の融点以上の温度で粘着力が低下する。 (A)のSP値-2≦(B)のSP値≦(A)のSP値+2 (I)
