Abstract
Abstract A radiation-sensitive, imageable article comprises in sequence a substrate, a vapor-deposited colorant layer capable of providing an optical density of at least 0.3 to 10 nm band of the electromagnetic spectrum between 280 and 900 nm, and a vapor-deposited graded metal/metal oxide or metal sulfide layer.

Claim 1
Independent Claim
47 words
A radiation-sensitive, imageable article comprising in sequence: a substrate, a vapor-deposited colorant layer capable of providing an optical density of at least 0.3 to a 10 nm band of the electromagnetic spectrum between 280 and 900 nm, and a vapor-deposited graded metal/metal oxide or metal sulfide layer.
Claim 2
Dependent Claim
47 words
A radiation-sensitive, imageable article comprising in sequence: a substrate, a vapor-deposited colorant layer capable of providing an optical density of at least 0.3 to a 10 nm band of the electromagnetic spectrum between 280 and 900 nm, and a vapor-deposited graded metal/metal oxide or metal sulfide layer.
Claim 3
Dependent Claim
20 words
The article according to claim 1 wherein said colorant provides an optical density in the range of 0.3 to 7.0.
Claim 4
Dependent Claim
21 words
The article according to claim 1 wherein said colorant layer has a thickness in the range of 3 to 1000 nm.
Claim 5
Dependent Claim
13 words
The article according to claim 1 wherein said substrate comprises a polymeric film.
Claim 6
Dependent Claim
96 words
The article according to claim 1 wherein said metal/metal oxide or metal sulfide layer comprises at least two components of (a) metal and (b) metal oxide or metal sulfide or combinations thereof of between 15 Å and 5×10 4 Å in thickness, said coating being characterized by having a composition which varies its proportions of said at least two components through a thickness of at least 15 Å in a continuous manner, said variation in proportions being further characterized by the ratio of said components only increasing or only decreasing through the thickness of the coating.
Claim 7
Dependent Claim
52 words
The article according to claim 1 wherein the smaller of the coating layer's (a) metal to (b) metal oxide or metal sulfide or combinations thereof, or (c) metal oxide or metal sulfide or combinations thereof to (d) metal ratios varies by at least 10% over a thickness of at least 15 Å.
Claim 8
Dependent Claim
24 words
The article according to claim 1 wherein said vapor-deposited graded metal/metal oxide or metal sulfide layer has a thickness of at least 3 nm.
Claim 9
Dependent Claim
17 words
The article according to claim 4 further comprising an organic abrasion-protective layer directly over said metal layer.
