COATED PRODUCT WITH A LOW EMISSION COATING HAVING AN ABSORBING LAYER INTENDED FOR CREATING A DESIRED BLUE COLOR WHEN CONSIDERED AT AN EXTRA-AXIAL ANGLES OF OBSERVATION

摘要

1. A heat-treated coated article comprising a coating supported by a glass substrate, the coating comprising:! the first and second infrared (IR) reflective layers containing silver, said infrared reflective layers being separated from each other by at least one dielectric layer that is interposed therebetween, and the first IR reflective layer is arranged closer to the substrate than a second infrared reflective layer; ! a substantially metallic absorbent layer consisting essentially of NiCr sandwiched between the first and second infrared reflective layers, which absorbent layer is sandwiched between and in contact with the first and second layers containing silicon nitride; and! in this case, essentially, the metal absorbing layer is placed in the coating so that the heat-treated coated product has a color coordinate a * of reflection from the glass side from about 0 to +2 at an observation angle of 45 ° to the normal, and color coordinate b * of reflection from glass side from about -10 to -4 at an angle of observation of 45 ° to the normal. ! 2. The coated product according to claim 1, in which a substantially metal absorbent layer is placed in the coating so that the coated product has a color coordinate a * of reflection from the glass side of about +0.5 to +1.5 at the viewing angle 45 ° to the normal, and the color coordinate b * for reflection from the glass side from about -9 to -5 at an observation angle of 45 ° to the normal. ! 3. The coated product according to claim 1, in which essentially a metal absorbing layer is placed in the coating so that the coated product has a color coordinate a * for reflection from glass
