2. Description of the Related Art Vinyl chloride resin is an excellent material having excellent physical and chemical properties. However, when it is subjected to heat molding, it is thermally decomposed to cause dehydrochlorination, and the product is colored. However, there is a disadvantage that the commercial value is reduced.

[0004] However, in recent years, vinyl chloride resins are relatively inexpensive and have excellent properties, so that their uses have been diversified, the chances of coating or printing the products have increased, and The number of cases in which the material is combined with other materials to form a composite has become extremely large.

However, these conventional compounding systems have difficulty in adhesion to other synthetic resin materials, and the coating film is peeled off. In particular, this problem tends to occur in a vinyl chloride resin composition containing a plasticizer, and improvement thereof is required.
