<p>A resin composition of propylene-ethylene random copolymer comprising (a) 100 parts by weight of a propylene-ethylene random copolymer having an ethylene content of 0,5-7 weight %, (b) 0.01-5 parts by weight of at least one alkali salt selected from the group consisting of alkali carboxylates, alkali beta -diketonates and alkali salts of beta -ketacetate, (c) 0.01-5 parts by weight of an organophosphoric compound, and (d) 0.01-0.5 parts by weight of a lithium aluminum compound. The organophosphoric compound is represented by the following formula (I): <CHEM> wherein R1 is hydrogen or an alkyl group having 1 to 4 carbon atoms, each of R2 and R3 is independently hydrogen or an alkyl group having 1 to 12 carbon atoms, M is a metal atom of an element selected from the group consisting of Group III, IV, XIII and XIV elements of the Periodic Table, and X is -OH when M is a metal atom of an element of Group III or XIII of the Periodic Table or X is =O or (-OH)2 when M is a metal atom of an element of Group IV or XIV of the Periodic Table, and the lithium aluminum compound is represented by the following formula (II): ÄAl2Li(OH)6ÜnY.mH2O wherein Y is an inorganic or organic anion, n is a charge of Y and m is a number of 3 or less.</p> |
