Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
103 words
A decorative laminate offering a glossy black outer appearance of improved durability, comprising: A. at least one base film; B. a translucent, black reflective metal coating comprising a chromium-containing metal having a black appearance, applied over one surface of said base film, said coating formed by heating said metal to an elevated temperature above its boiling point and above the normal vaporization temperature of the metal, and vapor depositing said metal on said base film while maintaining said metal at said elevated temperature; and C. a top coat comprising a clear thermoplastic resin, applied over the free surface of said translucent metal coating.
Claim 2
Dependent Claim
103 words
A decorative laminate offering a glossy black outer appearance of improved durability, comprising: A. at least one base film; B. a translucent, black reflective metal coating comprising a chromium-containing metal having a black appearance, applied over one surface of said base film, said coating formed by heating said metal to an elevated temperature above its boiling point and above the normal vaporization temperature of the metal, and vapor depositing said metal on said base film while maintaining said metal at said elevated temperature; and C. a top coat comprising a clear thermoplastic resin, applied over the free surface of said translucent metal coating.
Claim 3
Dependent Claim
50 words
The laminate of claim 1 wherein said base film is pigmented, a tie coat is present between said base film and said translucent metal coating, and an intermediate coat comprising an organic resinous coating material curable by ultraviolet light is present between said top coat and said translucent metal coating.
Claim 4
Dependent Claim
20 words
The laminate of claim 2 further including a heat-sensitive adhesive coating located on the free surface of said base film.
Claim 5
Dependent Claim
75 words
A coated article comprising at least one base film having a glossy black reflective metal coating thereon, said coating having improved durability and comprising a vapor deposited film of an intrinsically blackened chromium-containing metal formed by heating said metal prior to conducting the vapor deposition to a temperature above the boiling point of the metal and above the normal vaporization temperature of the metal, and maintaining said metal at said temperature throughout said vapor deposition.
Claim 6
Dependent Claim
75 words
A coated article comprising at least one base film having a glossy black reflective metal coating thereon, said coating having improved durability and comprising a vapor deposited film of an intrinsically blackened chromium-containing metal formed by heating said metal prior to conducting the vapor deposition to a temperature above the boiling point of the metal and above the normal vaporization temperature of the metal, and maintaining said metal at said temperature throughout said vapor deposition.
Claim 7
Dependent Claim
19 words
The article of claim 4 wherein said metal film is prepared to a thickness offering a translucent visual appearance.
Claim 8
Dependent Claim
20 words
A decorative laminate product comprising at least one transferable resin film having bonded thereto the metal coating of claim 4.
Claim 9
Dependent Claim
27 words
The article of claim 4 wherein said chromium-containing metal is selected from the group consisting of nickel-chromium alloys, chromium-iron alloys, chromium-steel alloys, pure chromium, and mixtures thereof.
Claim 10
Dependent Claim
13 words
The article of claim 7 wherein said chromium-containing metal comprises a nickel-chromium alloy.
