Patent ID: 7947373

Claim:
A highly reflective coated substrate having a blue color, comprising: a substrate; and a coating formed on the substrate, the coating comprising: a. a first dielectric layer comprising at least one metal oxide over the substrate and having a thickness ranging from 392 Å to 400 Å; b. a first metal layer over the first dielectric layer and having a thickness ranging from 112 Å to 121 Å; c. a first primer layer over the first metal layer and having a thickness ranging from 16 Å to 24 Å; d. a second dielectric layer over the first primer layer and having a thickness ranging from 976 Å to 984 Å, said second dielectric layer being a single film, and comprising an alloy of an oxide of zinc and tin; e. a second metal layer over the second dielectric layer and having a thickness ranging from 117 Å to 125 Å; f. a second primer layer over the second metal layer and having a thickness ranging from 16 Å to 24 Å; and g. a third dielectric layer comprising at least one metal oxide over the second primer layer and having a thickness ranging from 497 Å to 505 Å, wherein the coating includes only two metal layers and the coating is configured to provide an L* of at least 48, an a* of greater than b*/2, and a b* of less than −15.
