Problems solved by technology

[0007] However, Japanese Unexamined Patent Publication (Kokai) 2001-152077 has the problem that acrylic monomers having quaternary ammonium salt groups are often not readily available
[0008] Also, the technique of US 2006 / 0003274 A1 has the problem that it is difficult to apply uniformly because metal oxides or conductive polymers listed as conductive materials are not water-soluble

Embodiment 1

[0090] 2.0 parts by mass of component A1 (aqueous polyacrylic acid solution manufactured by Aldrich Co.) was diluted with 79.5 parts by mass of ion exchange water, and 10.0 parts by mass of component B1 (aqueous solution of trimethyloctadecylammonium chloride) was added, and then mixed. In addition, 8.5 parts by mass of component C2 (aqueous carbodiimide resin dispersion) was added, and then mixed to obtain an antistatic agent composition.

[0091] Dip the nonwoven fabric into the obtained antistatic agent composition, and use the nonwoven fabric to wipe the surface of the plastic plate (multi-layer light diffusion plate), thereby coating the surface of the plastic plate with the antistatic agent composition, and then drying, Form an antistatic film. In addition, the plastic plate (heat treatment for crosslinking) was heat-treated at 80° C. for 20 minutes to obtain a plastic material (plastic optical element) coated with an antistatic agent composition on the surface.

Embodiment 2 to 5

[0093] In the same manner as in Example 1, except that the composition was replaced with each composition shown in Table 1, an antistatic agent composition was obtained. In the same manner as in Example 1, a plastic material (plastic optical element) coated with the antistatic agent composition on the surface was obtained.

[0095] Example 1

Embodiment 6 to 9 and comparative example 1

[0097] In the same manner as in Example 1, except that the composition was replaced with each composition shown in Table 2, an antistatic agent composition was obtained. In the same manner as in Example 1, a plastic material (plastic optical element) coated with the antistatic agent composition on the surface was obtained.

Abstract

The present invention provides an antistatic agent composition which attains sufficient antistatic properties and also has antistatic properties having excellent durability against high temperature, high humidity and ultraviolet irradiation. The antistatic agent composition of the present invention comprises a water-soluble resin having a carboxyl group, a crosslinking agent having a functional group capable of reacting with a carboxyl group, and an ammonium salt having a specific chemical structure. One or more crosslinking agents selected from a carbodiimide resin, an epoxy resin, an isocyanate resin and a zirconium salt are preferably used as the crosslinking agent. At least one kind of a water-soluble resin selected from the group consisting of polyacrylic acid and an acrylic acid-methacrylic acid copolymer is preferably used as the water-soluble resin.

Description

Technical field [0001] This application has been requested based on Japanese Patent Application No. 2006-167469 (June 16, 2006 Proposed on Japan) and 2006-273642 (made on October 5, 2006) of the Paris Convention priority, The entire contents of these applications are quoted in full in the description of this specification. [0002] The present invention relates to an antistatic agent composition having sufficient antistatic properties and excellent durability against high temperature, high humidity and ultraviolet radiation. Background technique [0003] In modern society, plastics are used for various purposes, but the problem is that because plastics are insulators, they are prone to static electricity, and dirt and dust will be adsorbed on the surface by charging, thereby degrading design performance. [0004] As one of the methods for solving such problems, a method is known which includes coating an antistatic agent containing a surfactant as a main component on the sur...
