Coating composition with solar properties

1. A coating comprising:

a. an infrared reflective layer;

b. a primer layer over the infrared reflective layer;

c. a dielectric layer over the primer layer; and

d. an absorbing layer;

wherein the absorbing layer can be either under the infrared reflective layer or over the dielectric layer;

wherein the absorbing layer comprises an alloy and/or mixture of (a) a metal having an index of refraction at 500 nm less than or equal to 1.0 and (b) a material having a ΔG° f of greater than or equal to −100 at 1,000°K; and

wherein the metal is silver and the material is tin.

2. The coating according to claim 1 , wherein the absorbing layer is deposited using a method selected from CVD spray pyrolysis, and MSVD.

3. The coating according to claim 1 , wherein the absorbing layer has a thickness ranging from 20 Åto 300 Å.

4. The coating according to claim 1 , wherein the dielectric layer comprises a material selected from metal oxides, oxides of metal alloys, nitrides, oxynitrides, and mixtures thereof.

5. The coating according to claim 4 , wherein the dielectric layer comprises a metal oxide selected from an oxide of titanium, hafnium, zirconium, niobium, zinc, bismuth lead, indium, tin, and mixtures thereof.

6. The coating according to claim 4 , wherein the dielectric layer comprises a zinc/tin alloy oxide ranging from 10 wt. % to 90 wt. % zinc and 90 wt. % to 10 wt. % tin.

7. The coating according to claim 1 , wherein the infrared reflective layer comprises a material selected from silver, gold and copper.

8. The coating according to claim 1 deposited on a 0.16 inch thick clear glass substrate wherein the substrate exhibits an Lta of less than or equal to 50% and an L* of equal to or less than 52 from at least one side of the substrate.
