Title (EN) ANTIFOG LAMINATE
(FR) STRATIFIÉ ANTIBUÉE
(JA) 防曇性積層体
Abstract:
(EN) The main purpose of the present invention is to impart a greater antifog property 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) 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, and 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).
(FR) L’objectif de l’invention est de conférer une propriété antibuée plus importante à un matériau hydrophile qui a été précédemment présenté par les présents inventeurs et qui comprend une résine réticulée sur la surface de laquelle sont séparés des groupes hydrophiles. Selon l’invention, un stratifié est pourvu d'une couche d'absorption d'eau (B) et d'une couche hydrophile (A) dans cet ordre sur un substrat, la couche hydrophile (A) comprenant une résine réticulée ayant un groupe hydrophile anionique, cationique ou non ionique, le gradient (force du groupe hydrophile au niveau d'une surface de la couche hydrophile (A)/force du groupe hydrophile au niveau d’un point à 1/2 l'épaisseur de la couche hydrophile (A)) des groupes hydrophiles dans la couche hydrophile (A) étant de 1,1 ou plus, et la couche d'absorption d'eau (B) comprenant une résine réticulée ayant un taux d'absorption d'eau dans la plage de 5 à 500 % en poids par unité de masse (g).
(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)に当たりの吸水率が5~500wt%の範囲の架橋樹脂からなる。
