Abstract
A method for modifying the appearance of a substrate is disclosed. The method includes providing a substrate having first and second opposing surfaces and depositing a reflectance modifying coating on at least a portion of the first surface of the substrate, wherein the second surface has a visible light reflectance (R1) ranging from 5 to 20 percent.

A method for modifying the appearance of a substrate comprising:
- providing a substrate having first and second opposing surfaces;
- and
- depositing a reflectance modifying coating on at least a portion of the first surface of the substrate, wherein the second surface has a visible light reflectance (R1) ranging from 5 to 20 percent, wherein the reflectance modifying coating provides the coated article with a ΔE reflectance of less than or equal to 25 and a ΔE transmittance of less than or equal to 8.
A method for modifying the appearance of a substrate comprising:
- providing a substrate having first and second opposing surfaces;
- and
- depositing a reflectance modifying coating by a CVD process on at least a portion of the first surface of a substrate, wherein the second surface has a visible light reflectance (R1) ranging from 5 to 20 percent, wherein the reflectance modifying coating provides the coated article with a ΔE reflectance of less than or equal to 25 and a ΔE transmittance of less than or equal to 8.
A method for providing a brilliant appearance to an automotive vision panel, the method comprising:
- providing an automotive vision panel having a first surface and a second surface;
- and
- depositing a reflectance modifying coating on at least a portion of the first surface of the vision panel, wherein the reflectance modifying coating comprises at least one material having a refractive index in the range of 1.7 to 2.2 at a wavelength of 550 nm, wherein the reflectance modifying coating has a thickness of less than or equal to 200 Å, wherein the reflectance modifying coating provides a Δn of less than or equal to 0.30 over a range of 370 nm to 700 nm, wherein the reflectance modifying coating provides a ΔE reflectance of less than or equal to 25 and a ΔE transmittance of less than or equal to 8, and wherein the reflectance modifying coating provides the second surface with a visible light reflectance in the range of 5 to 20 percent.
