Abstract

The present invention provides an active energy ray-curable composition characterized by comprising: an active energy ray-curable compound (A), a resin (B) having an alicyclic structure and a quaternary ammonium salt, and dimethylacetamide organic solvent (C). Moreover, this invention provides the hardened|cured material of the said active energy ray curable composition, and the film which has a cured coating film. It is preferable that content of the said dimethylacetamide is the range of 5-200 mass parts with respect to 100 mass parts of said active energy ray-curable compounds (A). The problem to be solved by the present invention is to provide a coating liquid that has good water resistance to moisture and dew condensation in the air because it is less prone to clouding, gelation, and precipitation, so that it can form a coating that has excellent continuous productivity and An active energy ray-curable composition having a hard coat layer having excellent antistatic properties.

Description

technical field [0001] The present invention relates to an active energy ray curable composition, its cured product, and a film. Background technique [0002] Anti-reflection (LR) film that can be used on the surface of flat panel display (FPD) such as liquid crystal display (LCD), organic EL display (OLED), plasma display (PDP), etc. is formed by forming two layers with a large difference in refractive index on the film base The multi-layer structure (substrate / high refractive index layer / low refractive index layer) is realized. These layers require high scratch resistance to prevent scratches during the production process of the antireflection film, and high antistatic properties to prevent contamination and blocking of the film. In addition, since the antireflection film is an optical film, each layer needs to be highly transparent. [0003] As a method of imparting antistatic properties among the above-mentioned required properties, it has been proposed to use a materi...
