益々拡大しつつある。[Detailed Description of the Invention] Vinyl chloride resin molded products, especially sheets, tiles, films, etc., are inexpensive and have excellent chemical and physical properties, so they are used as interior materials for houses, cabinets for TVs, stereos, etc., etc. Used for many purposes. (Recently, attempts have been made to coat the surface with unsaturated polyester resin paint, etc. to give it a beautiful luster and texture, and the demand for this is increasing.

組成物は塩化ビニル系樹脂成型物に対する接着力が充分
でない欠点がある。In order to improve the adhesion between the vinyl chloride resin molding and the paint, an undercoat paint such as a Frethane sealer is usually applied during such application, but with conventional undercoat paints, this is applied and then dried. It takes a considerable amount of time to do so. If the top coat is applied without sufficient drying, good adhesion cannot be obtained, so shortening the drying time of the undercoat is an important issue in mass production. On the other hand, compositions made of unsaturated polyester resins and polyisocyanate compounds have recently been proposed as fast-drying undercoating paints, but these compositions have the disadvantage of not having sufficient adhesion to vinyl chloride resin moldings. be.
