A synthetic resin composition having reduced corrosion-causing tendency and coloration, said composition comprising (A) 100 parts by weight of a synthetic resin containing halogen and/or an acidic substance, and (B) 0.001 to 50 parts by weight of a hydrotalcite solid solution represented by the following formula (1) [(M12+)y1(M22+)y2]1-xMx3+(OH)2Ax/nn-.mH2O . . . (1) wherein M12+ represents at least one divalent metal cation, M22+ represents at least one divalent metal cation, M3+ represents a trivalent metal cation, An- represents an anion having a valency of n, and x, y1, Y2 and m are positive numbers represented by the following expressions 0<x</=0.5, 0<y1, 0<y2, 0.5</=y1+y2<1, and 0</=m<2; and a method for preventing the corrosion-causing tendency or coloration of a synthetic resin containing halogen and/or an acidic substance by using the above formula (1) compound. |
