B. Conventional technology Polyolefin resins have excellent properties, such as chemical resistance, ozone resistance, heat resistance, water resistance, and good electrical properties, and are lightweight and inexpensive, so they are used in home appliances and other applications. It is widely used as a T-industry material such as automobile parts, and is one of the materials whose demand is most expected to grow in the future. However, despite having these characteristics, when it comes to automobile parts, for example, from the perspective of energy conservation, various plastics are being used to make them lighter, and the amount of plastic used is increasing year by year. Its use is limited to only a few. One of the reasons preventing its widespread use is that polyolefin resins are nonpolar and crystalline, making painting and adhesion extremely difficult. Conventionally, adhesion has been improved by activating the surface of polyolefin resin molded products by plasma treatment or gas flame treatment, but these methods require complicated processes and require large equipment costs and time losses. However, it has the disadvantage that the surface treatment effect varies due to the complexity of the shape of the molded product and the effects of pigments and additives in the resin. Therefore, as a method for painting without these pre-treatments, various brimer compositions such as those found in polypropylene bumper coatings for automobiles have recently been proposed, but these involve the complexity of a two-coat finish. Coating compositions for one-coat finishing include chlorinated polyolefins and cyclized rubbers that have strong adhesion to polyolefin resins, but are weather and moisture resistant.

In order to compensate for these drawbacks, attempts have been made to mix chlorinated polyolefins with acrylic resins and alkyd resins, which have good paint properties, but originally acrylic resins and alkyd resins are not compatible with chlorinated polyolefins. It has poor solubility, which causes problems such as a decrease in the gloss of the coating film and a significant loss of appearance.
