Abstract
(EN)
The present invention provides a means for enabling the formation of an adhesive layer in which adhesiveness and reworkability are highly reconciled by reducing adhesiveness during peeling to be lower than adhesiveness in an adhered state. In addition, the present invention provides a means capable of reconciling adhesiveness and reworkability, improving the punching processability of an adhesive layer, reducing the substrate contamination thereof, lowering the peeling static voltage of the adhesive layer, and improving the wettability of the adhesive layer to a product to be adhered. The present invention relates to an adhesive composition comprising: an (A) component, which is a urethane prepolymer having two or more hydroxyl groups; a (B) component, which is a multifunctional (meth)acrylate; a (C) component, which is a cross-linking agent; a (D) component, which are cross-linking particles; a (E) component, which is a photoradical initiator; and an (F) component, which is an antistatic agent, wherein the amount of the (D) component is approximately 0.01-10 parts by weight on the basis of 100 parts by weight of the (A) component.

La présente invention a pour objet un moyen pour permettre la formation d'une couche adhésive dans laquelle l'adhésivité et l'aptitude au remaniement sont hautement conciliables par réduction de l'adhésivité pendant le pelage pour qu'elle soit inférieure à l'adhésivité dans un état collé. De plus, la présente invention a pour objet un moyen permettant de concilier l'adhésivité et l'aptitude au remaniement, d'améliorer l'aptitude au traitement par poinçonnage d'une couche adhésive, de réduire la contamination du substrat par celle-ci, d'abaisser la tension statique de pelage de la couche adhésive et d'améliorer la mouillabilité de la couche adhésive sur un produit à coller. À cet effet, la présente invention porte sur une composition adhésive comprenant : un composant (A), qui est un prépolymère d'uréthane ayant au moins deux groupes hydroxyle; un composant (B), qui est un (méth)acrylate multifonctionnel; un composant (C), qui est un agent de réticulation; un composant (D), qui est des particules de réticulation; un composant (E), qui est un initiateur photoradicalaire; et un composant (F), qui est un agent antistatique, la quantité du composant (D) étant d'environ 0,01 à 10 parties en poids pour 100 parties en poids du composant (A).

<과제> 본 발명은 박리시의 점착력을 점착 상태의 점착력보다 저감시키는 것에 의해 점착성과 리워크성을 높은 수준으로 양립한 점착제층의 형성을 가능하게 하는 수단을 제공한다. 또한, 본 발명은 점착성과 리워크성의 양립에 더해서 점착제층의 타발 가공성 및 기재 오염성을 개선하고, 점착제층의 박리 대 전압을 저하시키며, 점착제층의 피착체에 대한 젖음성을 향상시킬 수 있는 수단을 제공한다. <해결 수단> 본 발명은 (A)성분: 2개 이상의 수산기를 갖는 우레탄 프리폴리머, (B)성분: 다관능 (메타)아크릴레이트, (C)성분: 가교제, (D)성분: 가교 입자, (E)성분: 광 라디칼 개시제 및 (F)성분: 대전 방지제를 함유하고, (A)성분 100질량부에 대한 (D)성분의 함유량은 약 0.01질량부 이상 약 10질량부 이하인 것을 특징으로 하는 점착제 조성물에 관한 것이다.
