Anti-scatter, ultraviolet protected, anti-misting, electro-optical rearview mirror

A reduced ultraviolet radiation transmitting, electro-optic rearview mirror assembly comprising:

• first and second spaced, optically transparent elements mounted in a mirror case, said elements each having front and rear surfaces and defining a space between the rear surface of said first element and the front surface of said second element;
• an electro-optic medium confined in said space whose light transmittance is variable upon the application of an electric field thereto;
• means for applying an electric field to said electro-optic medium to cause variation in the light transmittance of said medium;
• a reflective coating on one surface of said second element adapted to reflect light incident thereon through said first element and said electro-optic medium;
• and
• ultraviolet radiation reducing means incorporated in said assembly for reducing ultraviolet radiation degradation of said electro-optic medium in said assembly;
• said first element being a laminate assembly including a pair of optically transparent panels adhered to one another by a polymer layer, said polymer layer incorporating said ultraviolet radiation reducing means and polyvinylbutyral sheeting plasticized with a plasticizer in an amount comprising at least about 19 parts of plasticizer per 100 parts of polyvinylbutyral resin.
