Claims
- 1. An olefin resin-based article having good gas barrier properties, consisting of an .alpha.-.beta.-ethylenically unsaturated carboxylic anhydride-grafted polyolefin having formed thereon an anchor coat, and, on said anchor coat, a 200-4,000 angstrom thick silicon oxide deposit film, wherein the .alpha.-.beta.-ethylenically unsaturated carboxylic anhydride-grafted polyolefin is a maleic anhydride-grafted polypropylene resin, the concentration of maleic anhydride units in said .alpha.-.beta.-ethylenically unsaturated anhydride-grafted polyolefin is from 0.01 to 10% by weight and wherein said olefin resin-based article is a stretched film which has been stretched before formation of the silicon oxide deposit thereon.

- 11. The olefin resin-based article as claimed in claim 6, wherein said anchor coat is present in an amount of from 0.01 to 0.5 g/m.sup.2 on a solid weight basis.
- 12. The olefin resin-based article as claimed in claim 6, wherein said anchor coat is present in an amount of from 0.1 to 0. 3 g/m.sup.2 on a solid weight basis.
- 13. An olefin resin-based article having good gas barrier properties, consisting of an .alpha.-.beta.-ethylenically unsaturated carboxylic anhydride-grafted polyolefin having formed thereon an anchor coat, and, on said anchor coat, a 200-4,000 angstrom thick silicon oxide deposit film, wherein the .alpha.-.beta.-ethylenically unsaturated carboxylic anhydride-grafted polyolefin is a maleic anhydride-grafted polypropylene resin, the concentration of maleic anhydride units in said .alpha.-.beta.-ethylenically unsaturated anhydride-grafted polyolefin is from 0.01 to 10% by weight and wherein said .alpha.-.beta.-ethylenically unsaturated carboxylic anhydride-grafted polyolefin is a stretched film which has been stretched before formation of the silicon oxide deposit thereon.
- 14. An olefin resin-based article as claimed in claim 13, wherein the olefin resin-based article before formation of the silicon oxide deposit film has a Bekk's surface smoothness of from 20,000-100,000 sec. and a maximum surface roughness (R.sub.max) of not more than 0.5 .mu.m.
- 15. An olefin resin-based article as claimed in claim 13, wherein said anchor coat is present in an amount of from 0.01 to 0.5 g/m.sup.2 on a solid weight basis.
- 16. The olefin resin-based article as claimed in claim 13, wherein said anchor coat comprises a polyisocyanate, polyurethane, polyester, polyethylene-imine or alkyl titanate.
- 17. The olefin resin-based article as claimed in claim 13, wherein said anchor coat comprises a polyisocyanate compound, a polyurethane, a urethane prepolymer, mixtures of polyisocyanate compounds, polyurethanes and urethane prepolymers or reaction products of polyisocyanate compounds, polyurethanes and urethane prepolymers.
- 18. The olefin resin-based article as claimed in claim 13, wherein said anchor coat comprises a mixture of a polyester polyol or a polyether polyol and a polyisocyanate compound.
- 19. The olefin resin-based article as claimed in claim 16, wherein said anchor coat is present in an amount of from 0.01 to 0.5 g/m.sup.2 on a solid weight basis.
- 20. The olefin resin-based article as claimed in claim 16, wherein said anchor coat is present in an amount of from 0.01 to 0.3 g/m.sup.2 on a solid weight basis.
