Problems solved by technology

However, the inventors of the present invention have conducted studies, and as a result, it has been found that adding a conductive substance to a mold release agent causes poor dispersion or poor dissolution of the conductive substance, and the stability (liquid stability) as a coating agent deteriorates, making it difficult to In the case of coating on the base material
In addition, it is also known that the above-mentioned conductive substance may inhibit the curing of the release agent, and the solvent resistance of the obtained release layer may be deteriorated.

Abstract

The invention relates to a water based antistatic releasing coating composition and an antistatic releasing film. The invention provides a novel water based antistatic releasing coating composition, which can form a cured film having an antistatic releasing layer with an excellent antistatic property and releasing performance, excellent liquid stability, and an excellent solvent resistant performance through one layer painting. The water based antistatic releasing coating composition comprises methylated melamine resin (A), hydroxyl containing organic modified siloxane (B), an acid catalyst (C), and a conductive polymer (D).

Description

technical field [0001] The present invention relates to a water-based antistatic release coating composition and an antistatic release film formed by coating the coating composition and curing it. Background technique [0002] Release films have been used as: engineering films for casting films such as polyurethane resins, acrylic resins, and vinyl chloride-based resins; protective films for adhesive layers such as adhesive tapes, adhesive sheets, and adhesive films; Engineering films used in the manufacture of electronic components such as ceramic green sheets and printed circuit boards. As a mold release film, the mold release film which formed the mold release layer which consists of a silicone type or a non-silicone type mold release agent mainly on the surface of a base film, such as a polyester film, is normally used. [0003] Usually, a release film is peeled off after molding a resin sheet, when using an adhesive film, or after manufacturing an electronic component,...
