Abstract
A method of making a random color filter array layer which comprises dispersing in an aqueous medium a water immiscible oily liquid having dyes and/or pigments dissolved or dispersed therein to form colored droplets and mixing the resulting dispersion with one or more other dispersions of different colors in a continuous aqueous phase having a film forming polymer dissolved therein and coating the resulting mixture onto a support layer. The color filter array is useful in image capture devices including digital cameras, scanners and photographic film.
