PROBLEM TO BE SOLVED: To provide a molded body retaining barrier abilities such as oxygen barrier and gasoline barrier abilities, even if subjected to severe handling. SOLUTION: The molding includes a molded base material and a specific gas barrier layer laminated on the base material. The gas barrier layer is composed of a hydrolytic condensate of a compound (L) and a neutralized product of a polymer (X) containing a carboxyl group. The compound (L) includes a compound (A) containing an M<SP>1</SP>(Al, Ti, or Zr) bonded with a hydrolyzable characteristic group and a compound (B) containing Si bonded with a hydrolyzable characteristic group. Part of the -COO- group of the polymer (X) is neutralized with a metal ion with not less than 2 valencies. Not less than 80 mol% of the compound (B) is a compound expressed by a specific formula. The ratio: [mole number of M<SP>1</SP>of compound (A)]/[mole number of Si of compound (B)] is within the range of 0.1/99.9-35.0/65.0. COPYRIGHT: (C)2011,JPO&INPIT |
