Document Type and Number:
WIPO Patent Application WO/2011/118762
Kind Code:
A1
Abstract:
Disclosed is a resin composition—which contains a polyolefin (A), an ethylene-vinyl acetate saponified copolymer (B) having 20-65 mol% of contained ethylene and at least 96% saponification of the vinyl acetate units, an ethylene-vinyl acetate saponified copolymer (C) having 68-98 mol% of contained ethylene and at least 20% saponification of the vinyl acetate units, and a pigment (E)—characterized by the mass ratio A/B being 3-99.5, the mass ratio B/C being 1-100, the mass ratio E/C being 0.04-50, and the amount of contained ethylene-vinyl acetate saponified copolymer C being 0.01-2.4 masses for every total of 100 masses of the polyolefin (A) and the ethylene-vinyl acetate saponified copolymer B. By means of melt-molding such a resin composition, a molded article, particularly a multilayered structure, is provided that: comprises a resin composition containing a polyolefin, EVOH, and a pigment; has favorable pigment dispersiveness; and is improved with respect to color unevenness.
