Title
(EN) REINFORCING FILM
(FR) FILM DE RENFORCEMENT
(JA) 補強フィルム
Abstract
(EN)
A reinforcing film (10) comprises a film substrate (1) and an adhesive layer (2) fixed/layered thereon. The adhesive layer is a photo-curable composition including a (meth)acrylic based polymer, a (meth)acrylic based oligomer, and a multifunctional compound. It is preferable that, when the adhesive layer is divided into three equal parts in the direction of thickness and the region that is furthest from the substrate side is taken as the surface layer region, the abundance of the multifunctional compound in the surface layer region accounts for at least 50% of the abundance of the multifunctional compound throughout the total thickness direction, and the abundance of the (meth)acrylic based oligomer in the surface layer region accounts for no more than 31% of the abundance of the (meth)acrylic based oligomer throughout the total thickness direction.

La présente invention concerne un film de renforcement (10) qui comprend un substrat de film (1) sur lequel est fixée/stratifiée une couche adhésive (2). La couche adhésive est une composition photodurcissable comprenant un polymère à base de (méth)acrylique, un oligomère à base de (méth) acrylique et un composé multifonctionnel. Il est préférable, lorsque la couche adhésive est divisée en trois parties égales dans la direction de l'épaisseur et que la région qui est la plus éloignée du côté substrat est prise comme région de couche de surface, que l'abondance du composé multifonctionnel dans la région de couche de surface représente au moins 50 % de l'abondance du composé multifonctionnel dans la direction de l'épaisseur totale, et que l'abondance de l'oligomère à base de (méth)acrylique dans la région de couche de surface représente au plus 31 % de l'abondance de l'oligomère à base de (méth)acrylique dans la direction de l'épaisseur totale.

補強フィルム(10)は、フィルム基材(1)上に固着積層された粘着剤層(2)を備える。粘着剤層は光硬化性組成物であり、(メタ)アクリル系ベースポリマー、(メタ)アクリル系オリゴマー、および多官能化合物を含む。粘着剤層を厚み方向に3等分し、基材側から最も遠い領域を表層領域とした場合に、表層領域における多官能化合物の存在量が、厚み方向全体の多官能化合物の存在量の50%以上であり、かつ表層領域における(メタ)アクリル系オリゴマーの存在量が、厚み方向全体の(メタ)アクリル系オリゴマーの存在量の31%以下であることが好ましい。
