Embodiment

[0081] Hereinafter, the present invention will be described in more detail using production examples, examples, and comparative examples, but the present invention is not limited to these examples. In addition, "%" and "part" in an Example are based on a weight part. In addition, glass transition temperature is the value measured by the differential scanning calorimeter. In addition, the number average molecular weight is the value measured by the gel permeation chromatography.

manufacture example 1

[0085] 16 parts of acrylic acid and 144 parts of methyl methacrylate were put into a four-necked flask equipped with a nitrogen inlet tube, a thermometer, a reflux condenser and a stirring device, and 320 parts of isopropanol were further added to prepare a monomer solution. Next, 3.2 parts of 2,2'-azobisisobutyronitrile were added to the monomer solution. Then, the temperature of the reaction system was raised to 80° C., and a radical polymerization reaction was carried out for 8 hours. Then, 22.4 parts of triethylamine and 300 parts of ion-exchanged water were added to the reaction system, fully stirred, and cooled to normal temperature. Thereby, the solution of (A-1) component whose non-volatile matter was 20% was obtained. Here, the amount of carboxylate anion groups of the component (A-1) was 0.00139 mol / g, the glass transition temperature was 100° C., and the number average molecular weight was 30,000.

Abstract

The present invention provides a novel coating agent with an excellent antistatic property, solvent resistance and adhesive resistance. The antistatic coating agent contains acroid resin (A) having carboxylate anion group, a polyfunctional aziridine compound (B) and a Pi conjugated conductive polymer (C) containing hetero atoms.

Description

technical field [0001] The invention relates to an antistatic coating agent and a plastic film obtained by coating the antistatic coating agent. Background technique [0002] When plastic films such as polyester films are wound or rewound, static electricity is likely to be generated when the film is spun or moved, and dust in the air may adhere to it or cause poor movement in the processing line. Therefore, in order to suppress the generation of static electricity, it has been proposed to incorporate an antistatic agent into the film in advance. [0003] However, when an antistatic agent is added to the raw plastic before film processing, the antistatic agent may ooze out on the surface of the film and cause creases, or the oozing antistatic agent may fall off, resulting in a decrease in antistatic performance. Therefore, a method of forming a film by applying a coating agent having an antistatic function to the surface of a film is considered. [0004] For antistatic coa...
