Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
57 words
An article of manufacture for use as an architectural product having a three-dimensional appearance comprising: a. a transparent substrate; b. a discontinuous pattern coating on one surface of said substrate said pattern comprising transparent areas; and c. a second pattern coating on a second surface, wherein said second pattern coating is visible through said discontinuous pattern coating.
Claim 2
Dependent Claim
57 words
An article of manufacture for use as an architectural product having a three-dimensional appearance comprising: a. a transparent substrate; b. a discontinuous pattern coating on one surface of said substrate said pattern comprising transparent areas; and c. a second pattern coating on a second surface, wherein said second pattern coating is visible through said discontinuous pattern coating.
Claim 3
Dependent Claim
12 words
An article according to claim 1, wherein said transparent substrate is glass.
Claim 4
Dependent Claim
15 words
An article according to claim 2, wherein said discontinuous pattern coating comprises ceramic enamel colorants.
Claim 5
Dependent Claim
16 words
An article according to claim 3, wherein said discontinuous pattern coating is applied by screen printing.
Claim 6
Dependent Claim
15 words
An article according to claim 4, wherein said second coating is a discontinuous pattern coating.
Claim 7
Dependent Claim
15 words
An article according to claim 4, wherein said second pattern coating is a continuous coating.
Claim 8
Dependent Claim
13 words
An article according to claim 6, wherein said second pattern coating is opaque.
Claim 9
Dependent Claim
19 words
An article according to claim 7, wherein said second pattern coating is on a surface of a second substrate.
Claim 10
Dependent Claim
20 words
An article according to claim 5, wherein said second pattern coating is deposited on a surface of a second substrate.
Claim 11
Dependent Claim
23 words
An article according to claim 9, wherein a third reflective coating is deposited on a surface whereby it reflects a discontinuous pattern coating.
Claim 12
Independent Claim
61 words
A method for producing a pattern coated product with a three-dimensional appearance comprising the steps of: a. applying a discontinuous pattern coating onto a first surface of a transparent substrate said pattern comprising transparent areas; and b. applying a second pattern coating onto a second surface of a substrate, whereby said second pattern coating is visible through said discontinuous pattern coating.
Claim 13
Independent Claim
61 words
A method for producing a pattern coated product with a three-dimensional appearance comprising the steps of: a. applying a discontinuous pattern coating onto a first surface of a transparent substrate said pattern comprising transparent areas; and b. applying a second pattern coating onto a second surface of a substrate, whereby said second pattern coating is visible through said discontinuous pattern coating.
Claim 14
Dependent Claim
21 words
A method according to claim 11, wherein said first discontinuous pattern coating and second pattern coating both comprise ceramic enamel colorants.
Claim 15
Dependent Claim
29 words
A method according to claim 12, wherein said discontinuous pattern coating is applied to the substrate by screen printing and said second coating is also a discontinuous pattern coating.
Claim 16
Dependent Claim
21 words
A method according to claim 12, wherein said second pattern coating is applied on the opposite surface of said transparent substrate.
Claim 17
Dependent Claim
12 words
A method according to claim 12, wherein said second coating is continuous.
Claim 18
Dependent Claim
13 words
A method according to claim 15, wherein said second pattern coating is opaque.
