ないので、同様に、前記した用途に用いるに適さない。Such a liquid plasticizer is blended in an amount of 10 to 45 parts by weight per 100 parts by weight of the vinyl chloride polymer. If the amount of liquid plasticizer is less than 10 parts by weight per 100 parts by weight of the vinyl chloride polymer, the resulting film will have high rigidity and low elongation, making it unsuitable for use in the above-mentioned applications. However, when it withstands 45 parts by weight, the resulting film is too flexible and has no stiffness, and is therefore similarly unsuitable for the above-mentioned applications.

低下が著しく、前記した用途への使用に適さない。The hydrotalcite compound is blended in an amount of 0.1 to 5.0 parts by weight based on 100 parts by weight of the vinyl chloride polymer. When the amount of the hydrotalcite compound is less than 0.1 part by weight per 100 parts by weight of the vinyl chloride polymer, it is not possible to sufficiently suppress the deterioration of the adhesive strength of the desired adhesive film over time. On the other hand, 5
．． When the amount exceeds 0 parts by weight, the elongation of the resulting film is significantly reduced, making it unsuitable for use in the above-mentioned applications.
