Method of making a color filter array element

摘要

A method of preparing a color filter array element comprising the following steps: a) coating a glass support with a polymeric dye image-receiving layer; b) coating the polymeric dye image-receiving layer with at least one additive primary color dye from a solvent that does not swell or penetrate the polymeric dye image-receiving layer; c) placing a stencil mask of a desired pixel shape in intimate contact with the surface of the polymeric dye image-receiving layer; d) fusing the dye into the polymeric dye image-receiving layer by heating or by using a solvent vapor treatment using a solvent which will swell or penetrate the dye image-receiving layer; e) removing the stencil mask; f) removing all unfused dye with a solvent wash; and g) repeating steps b) to f) twice using different additive primary color dyes.
