  • Patent number: 7250217
    Abstract: Plasticized films suitable as an intermediate layer in laminated safety glass and based on partially acetalized polyvinyl alcohols, in particular PVB, have not only the required excellent adhesion to glass but also undesired self-adhesion (susceptibility to blocking). Amounts of from 0.001 to 0.1% by weight of a pentaerythritol ester are proposed for use as an additive which reduces self-adhesion. This additive does not alter the adhesion of the film to glass. The invention is used for producing films for the production of laminated safety glass. The need to cool the films for stacking or wind-up is substantially eliminated.

  • Patent number: 6383647
    Abstract: This invention has its object to provide an interlayer film for laminated glass an interlayer film for laminated glass which, when assembled into laminated glass, offers good transparency, weathering resistance, adhesion, penetration resistance and other characteristics, does not cause marginal whitening of laminated glass even exposed to a highly humid atmosphere, and free from the risk for a fire hazard in autoclaving or the problem associated with edge trimming and a laminate glass comprising said interlayer film. This invention is related to an interlayer film for laminated glass comprising a plasticized poly(vinyl acetal) resin film, wherein, when a laminated glass fabricated by interposing said interlayer film between a pair of glass sheets each 2.0 to 4.0 mm thick is allowed to sit in an environment of 80° C. and 95% relative humidity for 2 weeks, the distance of whitening from its edge is not greater than 7 mm, and when said interlayer film for laminated glass is allowed to sit at 150° C.

  • Patent number: 6329061
    Abstract: The invention provides a laminated glass and a method of producing the same. This laminated glass includes first and second transparent glass plates and an interlayer film interposed therebetween. This interlayer film has functional ultra-fine particles which have a particle diameter of up to 0.2 &mgr;m and are dispersed therein. Due to the incorporation of the ultra-fine particles thereinto, the interlayer film is provided with various additional functions such as heat insulation, ultraviolet ray absorption and the maintenance of a sufficient radio transmittance. Therefore, the laminated glass becomes suitable as an architectural or automotive laminated glass.

  • Patent number: 6200683
    Abstract: The invention pertains to compositions which can be coated onto substrates. These compositions include a combination of a resin blend comprising a first polyester resin and a second polyester resin, wherein the first polyester is different from the second polyester, an aminoplast crosslinking resin, an acid catalyst, and a urea-aldehyde resin. Films prepared from coating compositions made in accordance with the present invention having improved stain resistance. In many instances, films prepared from coating compositions made in accordance with the present invention not only have improved stain resistance, but also have low temperature flexibility.

  • Patent number: 6086983
    Abstract: The force, by which the glass sheets of a laminated glass push onto each other, is applied to the edges of the laminated glass to prevent the delamination of the laminated glass caused by moisture penetrating or diffusing from these edges into the intermediate film. A pair of glass sheets having different curvatures, in which if the pair of glass sheets are laid on each other, aligning their edges, their central portions are apart from each other and do not adhere to each other, and in which if bent, their surfaces adhere to each other, are bonded with a PVB film, while being bent so that their surfaces adhere to each other to form a laminated glass. At the edges of the laminated glass, in the portion where the glass sheets try to regain their original shapes to push onto each other through the intermediate film, the delamination of the glass sheets is inhibited.
