Abstract: An interlayer comprised of a thermoplastic resin, at least one luminescent pigment and a carboxylic acid additive. The use of a thermoplastic resin, at least one luminescent pigment and a carboxylic acid additive reduces or minimizes the optical defects (such as high color or yellowness and increased haze) caused by discoloration of the pigment without sacrificing other characteristics of the interlayer.

Abstract: The present invention is a process for reducing the content of halogen bound to the silicon atom of halosilacycloalkanes. The process employs an alkylaluminum hydride as a reducing agent. Alkylaluminum hydrides have been found to be highly effective in removing the halogen bound to silicon, with lessor affect on the reactive silacycloalkane ring. In another embodiment of the present invention, the halosilacycloalkane is added beneath the surface of an excess of liquid alkylaluminum hydride. The temperature and the pressure of the reaction are maintained such that the resultant silacycloalkane products are immediately vaporized and removed from the reaction vessel. This minimizes further reaction of products and improves the yield of desired product.

Abstract: The invention relates to the selective and stepwise reduction of polyhalosilanes by reacting at room temperature or below with alkyltin hydrides without the use of free radical intermediates. Alkyltin hydrides selectively and stepwise reduce the Si--Br, Si--Cl, or Si--I bonds while leaving intact any Si--F bonds. When two or more different halogens are present on the polyhalosilane, the halogen with the highest atomic weight is preferentially reduced.

Abstract: The invention relates to the selective and sequential reduction of halodisilanes by reacting these compounds at room temperature or below with trialkyltin hydrides or dialkyltin dihydrides without the use of free radical intermediates. The alkyltin hydrides selectively and sequentially reduce the Si-Cl, Si-Br or Si-I bonds while leaving intact the Si-Si and Si-F bonds present.

Abstract: The invention relates to a method of forming amorphous, photoconductive, and semiconductive silicon films on a substrate by the vapor phase thermal decomposition of a fluorohydridodisilane or a mixture of fluorohydridodisilanes. The invention is useful for the protection of surfaces including electronic devices.
