Beschreibung
Zusammenfassung:	Provided is a resin composition, comprising: polyolefin (A); a saponified ethylene-vinyl acetate copolymer (B) having an ethylene content of from 20 to 65 mol% and having a degree of saponification of vinyl acetate units of 96% or more; a saponified ethylene-vinyl acetate copolymer (C) having an ethylene content of from 68 to 98 mol% and having a degree of saponification of vinyl acetate units of 20% or more; and a pigment (E), wherein a mass ratio (A/B) is from 3 to 99.5, a mass ratio (B/C) is from 1 to 100, a mass ratio (E/C) is from 0.04 to 50, and a content of the saponified ethylene-vinyl acetate copolymer (C) is from 0.01 to 2.4 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). By melt molding such resin composition, provided is a molded product, in particular a multilayered structure, made of the resin composition containing the polyolefin, the EVOHs, and the pigment, having good dispersibility of the pigment, and having improved uneven coloration.
