Problems solved by technology

However, the main agent or crosslinking agent is usually an aqueous solution or dispersion, so sometimes it is difficult to obtain a primer film in a short time
In addition, primer coats are generally less resistant to moisture and issues such as loss of adhesion over time have been noted

[0055] Production example 1

[0056] In a reaction vessel with a mixer, cooler, thermometer, and nitrogen inlet tube, add 479 parts of terephthalic acid, 402 parts of isophthalic acid, 87 parts of azelaic acid, 256 parts of ethylene glycol, 221 parts of 1,6- Hexylene glycol, 148 parts of neopentyl glycol and 7 parts of trimethylolpropane were heated to melt the reaction system with stirring. Then, the water produced in the dehydration condensation reaction was removed, and the temperature of the reaction system was slowly raised from 160°C to 200°C within 3 hours, and then kept at 200°C for 1 hour. Next, 0.16 parts of antimony trioxide was added. Then, a vacuum decompression device was connected to the reaction container, and a reduced-pressure compression polymerization reaction was carried out at 235° C. and 2.8 kPa for 1 hour. Then, 512 parts of methyl isobutyl ketone and 768 parts of methyl ethyl ketone were added and dissolved uniformly. Thereby, the solution of polye...

[0083] To 100 parts of the solution of the branched polyester resin (A-1) obtained in Production Example 1, 1.5 parts of pentaerythritol triacrylate (trade name "Biscoat #300": Osaka Organic Co., Ltd. Chemical Industry Co., Ltd.), mixing. Then, 8.9 parts of "Coronet HX" (uric acid body of hexamethylene diisocyanate (trade name: Nippon Polyuretan Industries, Ltd.)) as component (C) and 0.25 parts as (D) were added to this solution. Dioctyltin dilaurate as a component (trade name: "Neostan U-810": Nitto Kasei Co., Ltd.) was diluted with 131 parts of methyl ethyl ketone as component (E) to obtain a primer with a non-volatile content of 25%.

Abstract

The invention provides a novel base coat capable of forming a base coat layer and characterized by non-water base, adhesiveness and moisture resistance of the base coat layer and the curing film and plastic film formed by an active energy line curing film are excellent. As the base coat, a composition comprising the following ingredients is provided: a branched polyester resin (A) provided with a hydroxyl group, a compound (B) provided with an active energy line polymerizability functional group and a hydroxyl group, and a polyisocyanate (C) provided with at least three isocyanate groups.

Description

technical field [0001] The present invention relates to a non-water-based primer used as a primer layer of a laminated film having an active energy ray-curable film layer and a plastic film layer, and a plastic film having an active energy ray-curable film using the undercoat agent. Background technique [0002] Plastic films made of thermoplastic resins such as polystyrene films, polycarbonate films, and polyester films are used in various industrial applications. In particular, polyester films are used in various products due to their excellent mechanical strength and transparency. [0003] However, plastic films sometimes have difficulty adhering to cured films formed of energy-ray-curable materials such as pentaerythritol triacrylate (hereinafter, referred to as "active energy ray-curable films"). To improve adhesion, surface treatments such as corona discharge or sandblasting are also possible. However, there is a limit to improving the adhesiveness, and there is also ...
