Abstract: 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.

Abstract: 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° C. and an internal visible light transmission below 20% and an internal solar energy transmission below 20% when the interlayer is at 75° C. The internal haze of the interlayer is below 3.5%.

Abstract: A combination of layers comprised of: 1) a first LETC layer; 2) a second LETC layer and 3) a separator layer between the two LETC layers 4) an additive within at least one of the LETC layers and the separator layer wherein when the layers are laminated between two sheets of clear glass the color coordinate values of the laminate are about ?8.5?a*?about 8.5 and about ?8.5?b*?about 8.5 throughout the temperature range of about 0° C. to about 85° C.

Abstract: A vacuum window unit including two spaced apart and substantially parallel sheets of glass, a spacer having a plurality of walls perpendicular to the sheets of glass, the spacer defining a reticulated or a honeycomb or a cellular structure, and a vacuum, a partial vacuum, or a substantially reduced gas pressure as compared to a normal atmospheric pressure between the sheets of glass and within the cells of the spacer. The spacer is positioned between the two sheets of glass to maintain spacing between the two sheets of glass.

Abstract: Alternating layers of a first moisture sensitive layer are formed with a second desiccant containing layer. The desiccant containing layer removes moisture from the first moisture sensitive layer and maintains the first layer in a relatively dry condition.

Abstract: A stack or roll of alternating layers of films or sheets. The stack or roll includes an interlayer film or sheet with a thermochromic PVB of a polymer, at least one transition metal ion, at least one high epsilon ligand capable of forming a high epsilon metal-ligand complex with the transition metal ion and at least one low epsilon ligand capable of forming an low epsilon metal-ligand complex with the transition metal ion. A desiccant-containing film or sheet is juxtaposed or interleaved with the interlayer film or sheet. The desiccant-containing film or sheet prevents blocking of the interlayer film or sheet and is capable of removing moisture from the interlayer film or sheet. The desiccant-containing film or sheet is releasably attached to the interlayer film or sheet.
