A laminate comprising a near infrared (NIR) absorbing interlayer is disclosed. The interlayer includes a NIR-absorbing substance dispersed or dissolved in a polymer matrix and may further include a thermochromic material or system. The interlayer is bonded between first and second sheets of plastic or glass. The first and second sheets may further be bent, strengthened sheets of glass.

Absorbing solar control interlayers

A thermochromic, near infrared (NIR) absorbing interlayer. The interlayer includes a NIR-absorbing substance dispersed or dissolved in a polymer matrix and a thermochromic material or system. The interlayer has an internal visible light transmission above 50% and an internal solar energy transmission below 55% when the interlayer is at 15&#xb0; C. and an internal visible light transmission below 20% and an internal solar energy transmission below 20% when the interlayer is at 75&#xb0; C. The internal haze of the interlayer is below 3.5%.

Disclosed are compositions of matter which include a thin metallic and/or metallic oxide, nitride, carbide, silicide, boride, or sulfide coating disposed directly upon a polymeric substrate, in the absence of a carrier layer for the thin coating. Also disclosed are methods to make the composition and an apparatus to practice the method.
