Abstract
A coated glass article including a glass substrate and a coating deposited over the glass substrate. The coating includes a first inorganic metal oxide layer deposited over a major surface of the glass substrate. A second inorganic metal oxide layer is deposited over the first inorganic metal oxide layer. A third inorganic metal oxide layer is deposited over the second inorganic metal oxide layer. A fourth inorganic metal oxide layer is deposited over the third inorganic metal oxide layer. The coated glass article exhibits a total visible light transmittance (Illuminant C) of 40% or more and a visible light reflectance (Illuminant C) of 30% or more.
Claims18
A coated glass article comprising:
- a glass substrate;
- and
- a coating deposited over the glass substrate, wherein the coating comprises:
- i. a first inorganic metal oxide layer deposited over a major surface of the glass substrate, wherein the first inorganic metal oxide layer has a refractive index of less than 2.1,
- ii. a second inorganic metal oxide layer deposited over the first inorganic metal oxide layer, wherein the second inorganic metal oxide layer has a refractive index which is less than the refractive index of the first inorganic metal oxide layer,
- iii. a third inorganic metal oxide layer deposited directly on the second inorganic metal oxide layer at a thickness of 40 nm or less, wherein the third inorganic metal oxide layer comprises tin oxide,
- iv. a fourth inorganic metal oxide layer deposited over the third inorganic metal oxide layer, wherein the fourth inorganic metal oxide layer has a refractive index which is greater than a refractive index of the third inorganic metal oxide layer,
- wherein the coated glass article exhibits a total visible light transmittance (Illuminant C) of 40% or more and a film side visible light reflectance (Illuminant C) of 30% or more.
