The invention provides low solar reflectance, low-emissivity coatings. The invention also provides a pane bearing a low solar reflectance, low-emissivity coating. Further, the invention provides an insulating glass unit comprising first and second panes held in a spaced-apart configuration, wherein the panes have confronting inner surfaces oriented toward a between-pane space and opposed outer surfaces oriented away from the between-pane space, and wherein one of these inner surfaces bears a low solar reflectance, low-emissivity coating. Also provided are methods of producing coated substrates.

What is claimed is: 1. A method of producing coated substrates, the method comprising: a) providing a pane having generally-opposed first and second major surfaces; and b) depositing upon one of said major surfaces a low-emissivity coating comprising in sequence outwardly from the pane, an inner coat, a high absorption primary layer, a middle coat, and an infrared-reflective layer, the inner coat being deposited directly onto the pane, wherein said infrared-reflective layer comprises material that is highly reflective of infrared radiation, the high absorption primary layer comprises material that is highly absorptive of solar radiation and includes at least about 100 angstroms of film, the inner coat comprises at least one transparent dielectric film and has an optical thickness, the middle coat comprises at least one transparent dielectric film and has an optical thickness of between about 600 angstroms and about 1,800 angstroms, and wherein the coating has a ratio defined as the optical thickness of the inner coat divided by the optical thickness of the middle coat, said ratio being between about 0.15 and about 0.32. 2. The method of claim 1 wherein the infrared-reflective layer is deposited as a silver-containing film. 3. The method of claim 1 wherein the infrared-reflective layer is deposited as a film having a thickness of at least about 50 angstroms. 4. The method of claim 1 wherein the high absorption primary layer is deposited as a titanium-containing film. 5. The method of claim 4 wherein the high absorption primary layer is deposited as metallic titanium. 6. The method of claim 1 further comprising depositing a high absorption blocker layer between the infrared-reflective layer and the inner coat. 7. The method of claim 6 wherein the high absorption blocker layer is deposited as a titanium-containing film. 8. A method of producing coated substrates, the method comprising: a) providing a pane having generally-opposed first and second major surfaces; and b) depositing upon one of said major surfaces a low-emissivity coating comprising the following sequence of films: i) an inner coat comprising at least one transparent dielectric film, the inner coat being deposited directly on the pane; ii) a high absorption primary layer comprising material that is highly absorptive of solar radiation, the high absorption primary layer including at least about 100 angstroms of film; iii) a middle coat comprising at least one transparent dielectric film and having an optical thickness of between about 600 angstroms and about 1,800 angstroms; iv) an infrared-reflective layer comprising material that is highly reflective of infrared radiation; v) a high absorption blocker layer comprising material that is highly absorptive of solar radiation, the high absorption blocker layer being deposited directly over the infrared-reflective layer; and vi) an outer coat comprising at least one transparent dielectric film. 9. The method of claim 8 wherein the infrared-reflective layer is deposited as a silver-containing film. 10. The method of claim 8 wherein the infrared-reflective layer is deposited as a film having a thickness of at least about 50 angstroms. 11. The method of claim 8 wherein the high absorption primary layer is deposited as a titanium-containing film. 12.
