Abstract:
1. Glazing comprising (a) at least one electrochromic system having variable optical and/or energy properties, (b) at least one coating for adjusting the optical appearance conferred on the said glazing by the said system, said at least one coating having antireflection properties in the visible, wherein said coating having antireflection properties is deposited on at least one of the external faces of said glazing and comprises a stack of thin layers having alternately high and low reflective indices or a graded-refractive-index layer, and (c) at least one coating for attenuating/modifying the color of the glazing in reflection, wherein the coating (c) is in contact with the electrically controllable system (a), in the form of a thin layer having a refractive index intermediate between those of the materials with which it is in contact on each of its faces.
