Abstract: An objective of the present invention is to provide an anti-reflection film laminate which is for manufacturing an anti-reflection film having low surface reflectance and good anti-reflection properties, as well as excellent thermoformability and scratch resistance. The aforementioned problem is resolved by the following anti-reflection film laminate. This anti-reflection film laminate comprises: a first laminate having a base film that has a release surface, and an optical interference layer laminated on the release surface; and a second laminate having a substrate layer that contains a thermoplastic resin, and an uncured hardcoat layer that is laminated on one surface of the substrate layer and comprises a curable hardcoat composition. The first and second laminate bodies are pressure bonded such that the optical interference layer of the first laminate and the uncured hardcoat layer of the second laminate are in contact with each other.

Abstract: The problem addressed by this invention is to provide a laminate for molding having excellent moldability and post-curing properties of the hard-coat layer, and which can maintain the surface of the hard-coat layer in a satisfactory state while uncured. This problem is solved by a laminate for molding containing a hard-coat layer and a masking film affixed to the surface of the hard-coat layer, having an adhesive surface, which is the hard-coat layer-side surface of the masking film, with a surface free energy of at least 30.0 (mN/m) measured in accordance with the OWRK method, before being affixed. The hard-coat layer is in an uncured state.

Abstract: 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.
