A method of producing a radiation-induced colorant transfer image on a support, includes the steps of: providing an image-receiving element comprising a support having thereon an image-receiving layer; providing a colorant donor element having a colorant transfer layer on a colorant element support and wherein colorant can be transferred from a transfer surface of the colorant donor element to the image-receiving element in response to selectively applied radiation, the colorant element support being configured to provide a surface having peaks and valleys; pressing the colorant element support surface against a rigid element so as to cause the colorant transfer layer surface to conformally have peaks and valleys; causing the peaks of the colorant transfer layer to engage the image-receiving element; and applying radiation to the colorant donor element to cause colorant to transfer in the space between the image-receiving element and the colorant transfer layer surface corresponding to the valleys in the colorant transfer surface.

Spacing a donor and a receiver for color transfer

A method of producing a color filter array on a transparent support, includes the steps of: forming a polymer image-receiving layer on the transparent support; baking the polymer image-receiving layer on the transparent support so as to harden the polymer image-receiving layer; and imagewise thermally transferring different colorants to form multicolored pixels in the polymer image-receiving layer. The method further includes fixing the colorant pixels into the polymer receiving layer to form the color filter array; and coating the such formed color filter array with an overcoat.

Method of making a color filter array by thermal transfer

A method for preparing a color filter array element is diclosed which includes the steps of forming an assembly by providing a support on which is coated a polymeric dye image-receiving layer; a stencil pattern on the dye image-receiving layer with holes corresponding to the desired color pixel array pattern; and a dye donor sheet over the stencil. The dye donor has a support film overcoated with a mixture of color dye, polymeric binder, and light absorber. The method further includes exposing the assembly to high intensity light to briefly heat the dye layer and thereby transfer the dye from the donor to the polymeric dye receiving layer so that a colored pattern of pixel elements are formed in or on the image-receiving layer.

Color filter arrays by stencil printing

A method of forming a color filter array which includes forming only a single image mordant layer on a device and then exposing the mordant to a pattern representing an array of filter elements and developing areas of the mordant to provide separated filter elements. These filter elements are then selectively dyed different colors.
