Abstract

The present invention provides an active energy ray-curable composition for forming a cured film on a cyclic olefin-based resin substrate, a hard coat film using cyclic olefin-based resin as a substrate and a laminate. The composition has excellent adhesion to a cyclic olefin-based resin substrate and can provide scratch resistance. As the active energy ray-curable composition for forming a curedfilm on a cyclic olefin-based resin substrate, the active energy ray curable composition having a specific composition including silica fine particles, a polymerizable unsaturated compound, and a photopolymerization initiator is employed. As a result, a film excellent in scratch resistance and substrate adhesion can be obtained. In addition, the laminate formed by laminating a cured film layer ofthe active energy ray-curable composition and an inorganic substance layer in sequence on the cyclic olefin-based resin substrate has sufficient interlayer adhesion and further shows excellent characteristics in transparency, scratch resistance, hardness and crimpiness resistance.

Description

technical field [0001] The present invention relates to the production of an active energy ray-curable composition having excellent adhesion to a cyclic olefin-based resin substrate and capable of imparting scratch resistance, and a hard coat film having a cured coating layer of the composition method. The present invention also relates to a laminate using a cyclic olefin-based resin as a base material, and more specifically, to a laminate that is sequentially laminated on a cyclic olefin-based resin base material that has excellent adhesion to the base material and can impart scratch resistance. A laminate obtained by curing a coating layer and an inorganic substance layer of an active energy ray-curable composition having the same characteristics, and a method for producing the same. Background technique [0002] In recent years, cyclic olefin-based resin films have been increasingly used as optical components such as mobile phones, smartphones, and liquid crystal display...
