The present inventors focused their attention on the above evaluation results and, as a result of examining a drug to be used in combination with copper stearate, by promoting the whitening prevention effect of copper stearate by using melamine together, the heat resistance of copper stearate was lowered. We found the effect of suppressing

For example, it is effective in preventing whitening of chlorine-containing resin compositions using gray pigments (inorganic pigments) or brown pigments (inorganic pigments and organic pigments), and is lead-based regardless of the type of stabilizer. , C a -Z n based formulations, that is to both effects of organotin formulation was found. Although its mechanism of action is not clear, it is considered that melamine chelate with copper ion to suppress the heat resistance lowering effect of copper ion and, at the same time, exert a synergistic effect of maintaining the whitening prevention effect. The chlorine-containing resin referred to in the present invention means a vinyl chloride resin homopolymer, a copolymer mainly composed of vinyl chloride resin with another resin, or a polymer blend of vinyl chloride resin and another resin, which is mainly used for hard blending. However, it is not necessarily limited to a hard mixture.

る。The lead-based compounding is a compound in which lead stearate is used as a main stabilizer and calcium stearate and waxes are used in combination. The C a -Z n based formulations is obtained by a combination of wax and the calcium and zinc stearate as a main stabilizer. The organotin-based compounding is a compound in which alkyltin malate, alkyltin mercaptide, etc. are used as main stabilizers, and calcium stearate and waxes are used in combination.

Therefore, a fine powder is preferable because it is dispersed in the chlorine-containing resin as finely as possible. The amount used is 0.005 parts by weight or more, preferably 0.005 parts by weight, based on 100 parts by weight of the chlorine-containing resin.
˜2 parts by weight. If it is 0.005 parts by weight or less, the whitening prevention effect is small, and if it is 2 parts by weight or more, it is uneconomical.
