  When achieving high hardness by forming a hardcoat layer including only organic matter, cure shrinkage increases, a film on which the hardcoat layer is formed curls, and in extreme cases, the hardcoat layer is prone to cracking; on the other hand, when attempting to suppress cure shrinkage, it is difficult for sufficient high hardness to be exhibited. Furthermore, organic/inorganic hybrid curable resin compositions use inorganic matter such as silica in order to increase hardness. However, this leads to the problem of the inherent properties of the resin, such as workability, being lost. The abovementioned problems have been solved by a curable resin composition containing: a urethane (meth)acrylate, which is a reactant comprising norbornane diisocyanate and a compound having one hydroxyl group and one or more (meth)acryloyl groups in a molecule; and a (meth)acrylate monomer, which is a reactant comprising a polyol having a condensed polycyclic structure, and (meth)acrylic acid.

  通过形成仅包括有机物的硬涂层来实现高硬度时，固化收缩会增加，形成硬涂层的薄膜会卷曲，在极端情况下，硬涂层容易开裂；另一方面，如果试图抑制固化收缩，则很难表现出足够的高硬度。此外，有机/无机混合固化树脂组合物使用二氧化硅等无机物来提高硬度。然而，这会导致树脂固有特性（如可加工性）丧失的问题。一种可固化树脂组合物解决了上述问题，该组合物含有：氨基甲酸酯（甲基）丙烯酸酯，它是一种反应物，包括降冰片烷二异氰酸酯和在分子中具有一个羟基和一个或多个（甲基）丙烯酰基的化合物；以及（甲基）丙烯酸酯单体，它是一种反应物，包括具有缩聚多环结构的多元醇和（甲基）丙烯酸。
