  It is a main object of the present invention to impart higher antifogging properties and antireflective function to the hydrophilic material formed of a crosslinked resin and having a surface enriched with hydrophilic groups, which material was previously proposed by the inventors. The laminate of the present invention includes a water absorbing layer (B), an antireflective function-imparting layer (C) and a hydrophilic layer (A) provided in this order on a substrate, wherein the hydrophilic layer (A) is formed of a crosslinked resin having an anionic, cationic or nonionic hydrophilic group, and has a gradient of hydrophilic groups (intensity of hydrophilic group on surface of the hydrophilic layer (A)/intensity of hydrophilic group at 1/2 of thickness of the hydrophilic layer (A)) of not less than 1.1; the water absorbing layer (B) is formed of a crosslinked resin having a water absorption rate per unit mass (g) of in the range of 5 to 500 wt%; and the refractive index of a layer forming the layer (C) satisfies a specific condition.

  本发明的主要目的是使由交联树脂形成的、表面富含亲水基团的亲水材料具有更高的防雾性能和防反射功能，这种材料是发明者以前提出的。本发明的层压材料包括依次设置在基材上的吸水层（B）、抗反射功能层（C）和亲水层（A），其中亲水层（A）由具有阴离子、阳离子或非离子亲水基团的交联树脂形成、其中，亲水层（A）由具有阴离子、阳离子或非离子亲水基团的交联树脂形成，其亲水基团的梯度（亲水层（A）表面的亲水基团强度/亲水层（A）厚度 1/2 处的亲水基团强度）不小于 1。1；吸水层（B）由单位质量（g）吸水率在 5 至 500 wt%范围内的交联树脂形成；以及形成层（C）的折射率满足特定条件。
