Abstract
Abstract A metal-deposited paper comprising a paper substrate, a thin continuous coating of a film-forming resin having good adhesion to metals on at least one surface thereof, and a metal film deposited on the resin coating. The aforesaid paper can be produced by applying a thin continuous coating of a film-forming resin having good adhesion to metals on at least one surface of a paper substrate, and then vacuum-depositing a metal on the surface of the resin coating.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
96 words
A metal-deposited paper comprising a paper substrate, a thin continuous coating of an alkali metal ion cross-linked product of an ethylene/methacrylic acid copolymer, an ionomer resin, on at least one surface thereof, and an aluminum film vacuum-deposited on the resin coating to a thickness of about 100 to about 1000 A, said continuous resin coating having been formed by coating an aqueous dispersion of the ionomer resin in at least two coating cycles on the surface of the paper substrate so that the amount of solids coated is about 1 to about 30 g/m 2 .
Claim 2
Dependent Claim
96 words
A metal-deposited paper comprising a paper substrate, a thin continuous coating of an alkali metal ion cross-linked product of an ethylene/methacrylic acid copolymer, an ionomer resin, on at least one surface thereof, and an aluminum film vacuum-deposited on the resin coating to a thickness of about 100 to about 1000 A, said continuous resin coating having been formed by coating an aqueous dispersion of the ionomer resin in at least two coating cycles on the surface of the paper substrate so that the amount of solids coated is about 1 to about 30 g/m 2 .
Claim 3
Dependent Claim
36 words
The paper of claim 1 wherein said ionomer resin is an ethylene/methacrylic acid copolymer having 5 to 45% by weight of methacrylic acid units, 30 to 80% of which are neutralized with an alkali metal ion.
Claim 4
Dependent Claim
25 words
The paper of claim 1 wherein said ionomer resin contains at most 15% by weight, based on the weight of the resin, of polyvinyl alcohol.
Claim 5
Dependent Claim
20 words
The paper of claim 1 wherein said continuous resin coating has a thickness of about 1 to about 30 microns.
Claim 6
Dependent Claim
42 words
The paper of claim 1 wherein said continuous resin coating has been formed by coating the aqueous dispersion of the ionomer resin on the paper substrate so that the amount of solids coated is about 2 to about 20 g/m 2 .
Claim 7
Dependent Claim
21 words
The paper of claim 1 wherein said aqueous dispersion has a solids concentration of about 10 to about 60% by weight.
Claim 8
Dependent Claim
143 words
A metal-deposited paper having a high gloss metallic luster and low air- and moisture-permeability and substantially retaining the inherent mechanical properties of paper including bursting property, bendability, strength, elongation and hardness, said paper comprising a paper substrate, a thin continuous coating of an alkali metal ion cross-linked product of an ethylene/methacrylic acid copolymer, an ionomer resin, having a thickness of from about 2 to about 20 microns on at least one surface of the paper substrate, and an aluminum film having a thickness of from about 300 to about 700 angstroms vacuum-deposited on the resin coating, said continuous ionomer resin coating having been formed by coating in at least two coating cycles an aqueous dispersion of the ionomer resin on the surface of the paper substrate so that the amount of solids coated is from about 2 to about 20 g/m 2 .
Claim 9
Dependent Claim
143 words
A metal-deposited paper having a high gloss metallic luster and low air- and moisture-permeability and substantially retaining the inherent mechanical properties of paper including bursting property, bendability, strength, elongation and hardness, said paper comprising a paper substrate, a thin continuous coating of an alkali metal ion cross-linked product of an ethylene/methacrylic acid copolymer, an ionomer resin, having a thickness of from about 2 to about 20 microns on at least one surface of the paper substrate, and an aluminum film having a thickness of from about 300 to about 700 angstroms vacuum-deposited on the resin coating, said continuous ionomer resin coating having been formed by coating in at least two coating cycles an aqueous dispersion of the ionomer resin on the surface of the paper substrate so that the amount of solids coated is from about 2 to about 20 g/m 2 .
Claim 10
Dependent Claim
35 words
The metal-deposited paper of claim 7 wherein said aqueous dispersion of the ionomer resin further includes from about 0.03 to about 10% by weight of polyvinyl alcohol, based on the weight of the ionomer resin.
