Problems solved by technology

[0003] In addition, in these applications, in recent years, the requirements for low cost and high precision have become higher. If the hard coating agent is applied at high speed, the following problems will occur: it is easy to generate peeling static electricity, absorb suspended foreign matter in the air, and induce coating defects. lead to lower yield
[0005] However, the aforementioned polymethyl methacrylate substrate has high solvent resistance (corrosion resistance), and there is a problem that interference fringes are easily generated at the interface between the hard coat layer and the substrate.

Abstract

Provided are an active energy ray-curable composition and a film using the composition, the composition being characterized by containing: an active energy ray-curable compound (A); a resin (B) havingan alicyclic structure and a quaternary ammonium salt; and an organic solvent (C) containing at least 0.1 mass% and less than 15 mass% of an organic solvent (c-1) represented by general formula (1).The organic solvent (C) preferably further contains a hydrophobic solvent (c-2). The resin (B) is preferably a polymer obtained using, as a raw material, 5-55 mass% of a polymerizable monomer having an alicyclic structure. The blending amount of the resin (B) is preferably 0.1-30 parts by mass with respect to 100 parts by mass of the active energy ray-curable compound (A). The active energy ray-curable compound (A) preferably contains a high refractive index polymerizable monomer (A-1) having a refractive index of at least 1.55, and / or a polymerizable monomer (A-2) other than the monomer (A-1).

Description

technical field [0001] The present invention relates to an active energy ray-curable composition capable of forming a hard coat layer and a film using the same. Background technique [0002] Resin films are used for anti-scratch films on the surface of flat panel displays (FPD) such as liquid crystal displays (LCDs), organic EL displays (OLEDs), and plasma displays (PDPs), decorative films (sheets) for interior and exterior of automobiles, and for windows Low reflection film, heat ray shielding film, etc. However, the surface of a resin film is soft and has low scratch resistance, so in order to compensate for this, a hard coating agent containing an active energy ray-curable composition or the like is usually applied to the surface of the film and cured, and the surface of the film is provided. hard coat. [0003] In addition, in these applications, in recent years, the requirements for low cost and high precision have become higher. If the hard coating agent is applied a...
