Problems solved by technology

[0006] However, the antistatic performance of the hard coating agent formulated with these antistatic agents is not sufficient.
Furthermore, when a large amount of antistatic agent is blended, the antistatic performance is improved, but there is a problem that bleeding of the antistatic agent occurs after use under hot and humid conditions

manufacture example 1

[0068] (Production example 1: Production of resin (B-1) having an alicyclic structure and quaternary ammonium salt)

[0069] Nitrogen gas was introduced into a flask equipped with a stirring device, a reflux cooling pipe, and a nitrogen gas introduction pipe, and the air in the flask was replaced with nitrogen gas. Thereafter, 54.7 parts by mass of 2-(methacryloyloxy)ethyltrimethylammonium chloride, 19.9 parts by mass of cyclohexyl methacrylate, methoxypolyethylene glycol methacrylate ("Blemmer PME-1000" manufactured by NOF Corporation; number of repeating units n≒23, molecular weight 1,000) 24.9 parts by mass, 0.5 parts by mass of methacrylic acid, 50 parts by mass of methanol, and propylene glycol monomethyl ether (Propylene Glycol Monomethyl Ether, PGME) 10 parts by mass. Then, after dripping the solution which melt|dissolved 0.1 mass part of polymerization initiators (azobisisobutyronitrile) with 2.4 mass parts of PGME over 30 minutes, it was made to react at 65 degreeC f...

Abstract

The invention provides an active energy ray curable composition, and a cured product and a film using the same. The active energy ray curable composition contains an active energy ray curable compound(A), a resin (B) having an alicyclic structure and a quaternary ammonium salt, a compound (C) having a quaternary ammonium salt and not having an alicyclic structure, and an organic solvent (D). Themass ratio [(B) / (C)] of the resin (B) to the compound (C) is preferably in the range of 5 / 95 to 40 / 60. The total blending amount of the resin (B) and the compound (C) is preferably in the range of 1 part by mass to 10 parts by mass with respect to 100 parts by mass of the active energy ray curable compound (A). The subject of the present invention is to provide an active energy ray curable composition capable of forming a hard coat layer having both excellent antistatic properties and excellent penetration resistance; and a film using the active energy ray curable composition.

Description

technical field [0001] The present invention relates to an active energy ray curable composition, a cured product and a film using the same. Background technique [0002] Various resin films can be used for anti-corrosion on the surface of flat panel displays (FPD) such as liquid crystal displays (Liquid crystal display, LCD), organic electroluminescent displays (Organic Electroluminescent Display, OLED), and plasma displays (Plasma DiasplayPanel, PDP). Scratch films, decorative films (sheets) for interior and exterior of automobiles, low reflection films for windows, and heat ray cut films. However, since the surface of the resin film is soft and has low scratch resistance, in order to compensate for the disadvantages, a hard coating agent containing an ultraviolet (ultraviolet, UV) curable composition or the like is usually applied to the film surface and hardened. Instead, a hard coat layer is provided on the film surface. Outlining the steps of forming a hard coat laye...
