Abstract: A color filter for an AMLCD panel has a pattern of multi-color dots, each dot having red, green, and blue components in a black matrix. Each component is the cured product of a color pigment dispersed in a radiation-curable ink. The ink may be an ink curable by a cationic mechanism, a free-radical ink, or a hybrid, free-radical/cationic ink. The filter is produced by successively applying patterns of colored inks to a transfer roll, collecting the patterns on a collector roll to form an array of multi-color dots that is transferred to the substrate, and irradiating the array of dots to at least partially cure the inks.

Abstract: The present invention is a process for the production of organosilanes from the high-boiling residue resulting from the reaction of organohalides with silicon metalloid in a process typically referred to as the "direct process." The present process comprises forming a mixture comprising a organotrihalosilane and the high-boiling residue in the presence of hydrogen gas, a hydrogenolysis catalyst, and a redistribution catalyst. The organotrihalosilane and high-boiling residue are converted into commercially useful di- and triorganosilanes and organohydrosilanes. The present process results in consumption of the organotrihalosilane rather than the net increase which typically occurs in the absence of the redistribution catalyst.
