Abstract
A method for preparing a color filter array element is disclosed which includes coating an image receiving layer on one surface of a thin support, with the thin support being rigid in the horizontal plane. Thereafter, a colored pattern of pixel cells is transferred from a colorant donor sheet onto the image receiving layer. The method further includes laminating to a surface of a rigid, transparent support either the coated surface of the thin, rigid support carrying the colored pattern of pixel cells or the other surface of the thin, rigid support, to thereby form the color filter array element.

A method of making a color filter array element by colorant transfer, comprising the steps of:
- a) forming an image receiving surface on one surface of a thin support, with the thin support being rigid in the horizontal plane;
- b) transferring colorant to form a colored pattern of pixel cells in or on the image receiving surface;
- and
- c) laminating to a surface of a rigid, transparent support having substantially the same thermal expansion characteristics as the thin, rigid support, either the coated surface of the thin, rigid support carrying the colored pattern of pixel cells or the other surface of the thin, rigid support, to thereby form the color filter array element.
