Abstract
Abstract 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
123 words
A method for preparing a color filter array element comprising the steps of: a) forming an assembly by providing: i) a support on which is coated a polymeric dye image-receiving layer; ii) a stencil pattern on the dye image-receiving layer with holes corresponding to the desired color pixel array pattern; and iii) a dye donor sheet over the stencil, the dye donor having a support film overcoated with a mixture of color dye, polymeric binder, and light absorber; and b) 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.
