Resin composition and multilayered structure using same

A resin composition, comprising:

• (A) a polyolefin;
• (B) a saponified ethylene-vinyl acetate copolymer comprising an ethylene content of from 20 to 65 mol % and having a degree of saponification of vinyl acetate units of 96% or more;
• (C) a saponified ethylene-vinyl acetate copolymer comprising an ethylene content of from 68 to 98 mol % and having a degree of saponification of vinyl acetate units of 20% or more;
• (D) a random copolymer consisting of ethylene and vinyl acetate;
• (E) a pigment;
• and
• (I) a lubricant,
• wherein:
• a mass ratio of the polyolefin (A) and the saponified ethylene-vinyl acetate copolymer (B), (A/B), is from 3 to 99.5;
• a mass ratio of the saponified ethylene-vinyl acetate copolymer (B) and the saponified ethylene-vinyl acetate copolymer (C), (B/C), is from 2 to 18;
• a mass ratio of the random copolymer consisting of ethylene and vinyl acetate (D) and the saponified ethylene-vinyl acetate copolymer (C), (D/C), is from 0.1 to 15;
• a mass ratio of the pigment (E) and the saponified ethylene-vinyl acetate copolymer (C), (E/C), is from 0.1 to 1.2;
• a content of the saponified ethylene-vinyl acetate copolymer (C) is from 0.33 to 1.5 parts by mass, based on 100 parts by mass of a total amount of the polyolefin (A) and the saponified ethylene-vinyl acetate copolymer (B);
• a content of the lubricant (1) is from 0,00001 to 1 parts by mass, based on 100 parts by mass of the total amount of (A) and (B);
• the pigment (E) comprises titanium oxide particles comprising a surface coated with a compound of a metal other than titanium or a silicon compound;
• and
• the titanium oxide particles have an average particle diameter of from 0.01 to 0.4 μm.
