Colour filter elements.

摘要

A photographic method for making a color filter element, comprising the steps of: a) providing a photoelectrographic element comprising a conductive layer in electrical contact with an acid photogenerating layer 1) which is free of photopolymerizable materials and 2) comprises an electrically insulating binder and an acid photogenerator; b) carrying out the following steps i) and ii) at the same time or in any order; i) imagewise exposing the photoelectrographic layer through a first mask; ii) electrostatically charging the exposed layer to form a first electrostatic latent image; c) developing the latent image with charged toner particles of a single color; and d) fusing the toner particles with heat thereby forming a single color filter array.
