Problems solved by technology

[0003] In addition, in these applications, the demand for low cost and high precision has increased in recent years, but there is a problem that if the hard coating agent is applied at high speed, peeling and electrification are likely to occur , and absorb floating foreign matter in the air to cause coating film defects, resulting in a decrease in yield
However, when the coating film of the hard coat composition is dried, the particle aggregation process and the antistatic development process are mixed, so it is very difficult to achieve both low haze and antistatic properties required for the development of antiglare properties.

[0080] The active energy ray-curable compound (A) and the antistatic agent (B) used were changed as shown in Tables 1 to 4, except that the types and usage amounts of the active energy ray-curable compound (A) and antistatic agent (B) were changed in the same manner as in Example 1 to prepare an active energy ray-curable compound (A) and antistatic agent (B). sex composition.

[0081] [Preparation of samples for evaluation]

[0082] The active energy ray-curable compositions obtained in Examples and Comparative Examples were coated on a polymethyl methacrylate film having a thickness of 5 μm using a bar coater, and dried at 60° C. for 1 minute. Under a nitrogen atmosphere, use an ultraviolet irradiation device (manufactured by EYEGRAPHICS Co., Ltd., high-pressure mercury lamp) to irradiate at a light intensity of 75 mJ / m 2 The irradiation was performed twice to obtain a polymethyl methacrylate film having a cured coating film as a sample for evaluation.

Abstract

The present invention provides an actinic ray curable composition containing an actinic ray curable compound (A) and an antistatic agent (B), the actinic ray curable composition being characterized in that the antistatic agent (B) has a cationic moiety represented by formula (1). Also provided is a film that uses the actinic ray curable composition. This actinic ray curable composition is capable of forming a hard coating layer having excellent glare-proof performance and antistatic performance.

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 decoration of automobiles, and for Various applications such as low-reflection films for windows and heat ray blocking films. However, the surface of the resin film is soft and has low scratch resistance, so in order to compensate for this disadvantage, a hard coating agent containing an active energy ray-curable composition or the like is generally applied to the film surface and cured, thereby A hard coat layer is provided on the surface of the film. [0003] In addition, in these applications, the demand for low cost and high precision has increased ...
