The organic binder is a water-soluble polymer. The fibers coated with the ceramic powders are contacted with a cross-linking agent which reacts with binder to form a gel.

Abstract: The invention relates to methods and apparatus useful for making color filters for liquid crystal display panels. A multicolored ink pattern is deposited to a substrate while in a deformable state, flattened during the deposition process, and the deformed, more uniform shape of the printed dot is thereafter retained, preferably by curing during deposition. The transfer layer is preferably formed on a collector roll. A plurality of colored ink patterns is then transferred to the collector roll, preferably from a single pattern roll having multiple patterns thereon, to form the multicolor image that will become the color filter. This multicolored image is then transferred to the substrate.

Abstract: A method and apparatus for making contoured planarizing or protective layers for color filters for liquid crystal display panels. A transfer layer is formed on a collector device having a contoured surface. A plurality of colored ink patterns is formed on the transfer layer thereby forming the multicolor image that will become the color filter. This multicolored image is then transferred to the substrate so that the transfer layer in effect becomes a top protective layer or planarizing layer. The contoured surface on the collector device is imparted to the planarizing layer.

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: A method and apparatus for printing a multi-color ink pattern on a substrate surface which comprises arranging a series of patterned surfaces with each patterned surface having a pattern that is unique to one of the colors and that corresponds to the pattern of that color in the multi-color pattern, supplying to each patterned surface a radiation-curable ink formulation, having an appropriate colorant to form an ink pattern thereon, transferring individually the color pattern from each patterned surface to a collector roll, increasing the cohesiveness of the ink sufficiently to permit complete transfer of the pattern, forming a composite of the color patterns on a collector roll, and transferring the composite pattern in its entirety to the substrate surface.

Abstract: A method and apparatus for making color filters for liquid crystal display panels. A transfer layer is formed on a collector roll, and a raised pattern corresponding to the desired black matrix pattern is formed on the transfer layer by an embossing means. A plurality of colored ink patterns is formed in the appropriate location within the boundaries formed by the raised pattern, thereby forming the multicolor image that will become the color filter. This multicolored image is then transferred to the substrate. Preferably, the multicolored ink pattern is deposited to a substrate while in a deformable state, flattened during the deposition process, and the deformed, more uniform shape of the printed cells is thereafter retained, preferably by curing during deposition to the substrate.

Abstract: This invention is drawn to a method for eliminating the grayish discoloration which customarily develops when lead-free and cadmium-free glass frits are applied to substrates employing an organic vehicle and which are thereafter fired to fuse the frit particles into a glaze. The grayish hue results from a carbonaceous residue left upon thermally decomposing the organic vehicle. The inventive method comprises five general elements:(a) glass frit particles of a desired composition are prepared;(b) a coating of an organic compound containing at least one sulfur oxide group as an oxidizing agent is adsorbed on the surface of the particles;(c) the coated particles are mixed with an organic vehicle;(d) that mixture is coated onto a surface of a substrate; and(e) that coated substrate is fired to fuse the frit particles into a glaze, the oxidizing agent eliminating the carbonaceous residue left upon thermal decomposition of the organic vehicle.
