Abstract
Abstract A transparent laminate is disclosed, which laminate comprises a transparent plastic resin film or sheet substrate (A), a thin layer (B) of at least one metal such as aluminium, tin, iron, zinc, or magnesium formed on the film or sheet substrate (A) by vacuum deposition or sputtering, and a carboxyl group-containing polyolefin layer (C) formed on the metal layer (B) by lamination. In one embodiment, the film or sheet substrate may have a silicon oxide or titanium oxide layer (D) formed thereon by vacuum deposition or sputtering of the oxide.

Independent Claim
81 words
A transparent laminate comprising a transparent plastic resin film or sheet substrate (A), a thin layer (B) of at least one metal selected from the group consisting of aluminium, tin, iron, zinc and magnesium, said layer being formed on said plastic resin film or sheet substrate (A) by vacuum deposition or sputtering of the metal thereon and having a thickness ranging from monomolecular to 100 angstrom, and a carboxyl group-containing polyolefin layer (C) formed on said metal layer (B) by lamination.
Claim 2
Dependent Claim
81 words
A transparent laminate comprising a transparent plastic resin film or sheet substrate (A), a thin layer (B) of at least one metal selected from the group consisting of aluminium, tin, iron, zinc and magnesium, said layer being formed on said plastic resin film or sheet substrate (A) by vacuum deposition or sputtering of the metal thereon and having a thickness ranging from monomolecular to 100 angstrom, and a carboxyl group-containing polyolefin layer (C) formed on said metal layer (B) by lamination.
