Abstract
The crystalline synthetic resin composition of the present invention comprises 100 parts by weight of a crystalline synthetic resin compounded with (a) 0.01 to 5 parts by weight of at least one of alkali-metal carboxylates, alkali metal .beta.-diketonates and alkali metal salts of .beta.-ketoacetic esters and (b) 0.01 to 5 parts by weight of at least one of basic polyvalent metal salts of cyclic organophosphoric esters of the following general formula (I): ##STR1## wherein R.sub.1 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, R.sub.2 and R.sub.3 each represent a hydrogen atom or an alkyl group having 1 to 12 carbon atoms, M represents a group III or IV metal atom of the periodic table, and X represents HO--when M represents a group III metal atom of the periodic table and X represents 0.dbd. or (HO).sub.2 --when M represents a group IV metal atom of the periodic table. The compositions can be used for packaging materials, and coated molded articles.
