Title (EN) ADHESIVE AGENT AND ADHESIVE SHEET
(FR) AGENT ADHÉSIF ET FEUILLE ADHÉSIVE
(JA) 粘着剤および粘着シート
Abstract:
(EN) The purpose of the present invention is to provide: an adhesive agent which has a satisfactorily high nonvolatile component fraction, a satisfactory pot life, and satisfactory coating properties, and can be used as a one-part curable agent having good heat resistance; and an adhesive sheet. The adhesive agent contains: an acrylic polymer (A) obtained through polymerization of a monomer mixture containing 6-18 mass% of an acidic group-containing monomer (a1) and 15-94 wt% of 2-ethylhexyl acrylate in the presence of a chain transfer compound; a chelate curing agent (B); an organic solvent (C) (excluding an alcohol (D)); and an alcohol (D) and/or a keto-enol tautomer formation compound (E), wherein the chain transfer compound contains at least one selected from the group consisting of methyl ethyl ketone, thiols, and tackifying resins, and the nonvolatile component concentration is 52-75 mass%.
(FR) La présente invention vise à fournir un agent adhésif qui présente une fraction de composant non volatil suffisamment élevée, une durée de vie en pot satisfaisante, et des propriétés de revêtement satisfaisantes, et peut être utilisé comme agent durcissable à un composant ayant une bonne résistance thermique. L'invention concerne en outre une feuille adhésive. La présente invention concerne par conséquent un agent adhésif qui contient : un polymère acrylique (A) obtenu par polymérisation d'un mélange de monomères contenant de 6 à 18 % en masse d'un monomère contenant un groupe acide (a1) et 15 à 94 % en poids d'acrylate de 2-éthylhexyle en présence d'un composé de transfert de chaîne ; un agent durcisseur chélate ; un solvant organique (C) (à l'exclusion d'un alcool (D)) ; et un alcool (D) et/ou un composé de formation de tautomères céto-énolique (E), le composé de transfert de chaîne contenant au moins un élément sélectionné dans le groupe constitué de la méthyl éthyl cétone, des thiols et des résines collantes, et la concentration en composant non volatil est de 52 à 75 % en masse
(JA) 本発明は、高不揮発分、ポットライフ、および塗工性を満足しつつ、耐熱性が良好な一液硬化型として使用できる粘着剤、および粘着シートの提供を目的とする。連鎖移動化合物の存在下、酸性基含有モノマー(a1)6~18質量%、および2-エチルヘキシルアクリレートを15~94重量%を含むモノマー混合物を重合したアクリル系重合体(A)、キレート型硬化剤(B)、有機溶剤(C)(ただし、アルコール(D)は除く)、アルコール(D)およびケト-エノール互変異性体形成化合物(E)の少なくとも一方を含み、前記連鎖移動化合物は、メチルエチルケトン、チオールおよび粘着付与樹脂からなる群より選択される1種を含み、不揮発分濃度が52~75質量%である。
