Title (EN) ANTIREFLECTIVE LAMINATE
(FR) STRATIFIÉ ANTIREFLET
(JA) 反射防止性積層体
Abstract:
(EN) The main purpose of the present invention is to impart a greater antifog property and a greater antireflective function to a hydrophilic material that was previously presented by the present inventors and comprises a cross-linked resin wherein hydrophilic groups are segregated to a surface thereof. A laminate according to the present invention is provided with a water absorption layer (B), an antireflective function imparting layer (C), and a hydrophilic layer (A) in this order on a substrate, wherein the hydrophilic layer (A) comprises a cross-linked resin having an anionic, cationic, or nonionic hydrophilic group, the gradient (hydrophilic group strength at a surface of the hydrophilic layer (A)/hydrophilic group strength at a point at 1/2 the thickness of the hydrophilic layer (A)) of the hydrophilic groups in the hydrophilic layer (A) is 1.1 or greater, the water absorption layer (B) comprises a cross-linked resin with a water absorption rate in the range of 5-500wt% per unit mass (g), and the refractive index of a layer that makes up the layer (C) satisfies a particular condition.
(FR) L'objet principal de la présente invention est de conférer une propriété antibuée plus grande et une propriété antireflet plus grande à un matériau hydrophile qui a été précédemment présenté par les présents inventeurs et qui comprend une résine réticulée dans laquelle des groupes hydrophiles sont séparés sur une surface de celle-ci. Un stratifié selon la présente invention comprend une couche (B) d'absorption d'eau, une couche (C) conférant une fonction antireflet et une couche hydrophile (A) dans cet ordre sur un substrat. La couche hydrophile (A) comprend une résine réticulée comportant un groupe hydrophile anionique, cationique ou non ionique, le gradient (force des groupes hydrophiles au niveau d'une surface de la couche hydrophile (A)/force des groupes hydrophiles au niveau d'un point situé à 1/2 de l'épaisseur de la couche hydrophile (A)) des groupes hydrophiles dans la couche hydrophile (A) est supérieur ou égal à 1,1, la couche (B) d'absorption d'eau comprend une résine réticulée présentant un taux d'absorption d'eau dans la plage allant de 5 à 500 % en poids par unité de masse (g), et l'indice de réfraction d'une couche qui constitue la couche (C) satisfait à une condition particulière.
(JA) 本発明は、本発明者らが先に提案した親水基が表面に偏析した架橋樹脂からなる親水性材料にさらに高い防曇性と反射防止機能とを付与することを主な課題とする。本発明の積層体は、基材上に、吸水層(B)と反射防止機能付与層(C)と親水層(A)とがこの順に設けられており、前記親水層(A)が、アニオン性、カチオン性、またはノニオン性の親水基を有する架橋樹脂からなり、かつその親水層(A)における親水基の傾斜度(親水層(A)表面の親水基強度/親水層(A)の厚さ1/2地点の親水基強度)が1.1以上であり、前記吸水層(B)が、単位質量(g)当たりの吸水率が5~500wt%の範囲の架橋樹脂からなり、前記層(C)を構成する層の屈折率が特定の条件を満たす。
