Abstract
A resin composition, containing: (A) polyolefin; (B) a saponified ethylene-vinyl acetate copolymer having an ethylene content of from 20 to 65 mol % and a degree of saponification of vinyl acetate units of 96% or more; (C) a saponified ethylene-vinyl acetate copolymer having an ethylene content of from 68 to 98 mol % and 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 comprising titanium oxide particles comprising a surface coated with a compound of a metal other than titanium or a silicon compound; and (I) a lubricant; wherein a mass ratio (AB) is from 3 to 99.5, a mass ratio (B/C) is from 1 to 100, a mass ratio of (D/C) is from 0.1 to 15, a mass ratio (E/C) is from 0.04 to 50, and a content of (C) is from 0.01 to 2.4 parts, particularly 0.33 to 1.5 parts, by mass based on 100 parts by mass of (A) and (B). A molded product, in particular a multilayered structure, obtained by melt molding the resin composition has good dispersibility of the pigment, and improved uneven coloration.
