Abstract
Abstract A light reflex-refracting coating system effective to provide a resonant chamber for wavelengths of light desired to be trapped and transmit a selected sensible color from the object upon which the coating system is applied. The coating system has a base reflective surface, a dielectric coating such as aluminum oxide, having a thickness no greater than 500 angstroms, and an outer coating such as indium or tin, which is interrupted (such as by droplet formation in the thickness range of 500-10,000 A) to complete a resonant chamber.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
32 words
An optical coloring system as in claim 1, in which said interrupted coating and dielectric coating are effective to define a light resonant chamber oriented substantially parallel to said base reflective surface.
Claim 2
Dependent Claim
59 words
An optical coloring system as in claim 1, in which said reflective surface, dielectric, and interrupted coatings cooperate to define a resonant chamber characterized by a reflectance capability of 80 to 90 percent and an absorption characteristic of substantially 100 percent for selected wavelengths of light determined to be subtracted from the quantum of light entering said resonant chamber.
Claim 3
Dependent Claim
47 words
An optical coloring system as in claim 1, in which said base has a metallic reflective surface of a material selected from the group consisting of aluminum, magnesium; silver, and said interrupted coating is a metallic material selected from the group consisting of indium, tin and gold.
Claim 4
Dependent Claim
21 words
An optical coloring system as in claim 1, in which the dielectric coating is comprised of an oxide of said base.
Claim 5
Dependent Claim
18 words
An optical coloring system as in claim 1, in which said dielectric is comprised of a transparent material.
