Polyvinyl alcohol and polymeric barrier layer overcoats on colour filter arrays

摘要

This invention relates to a process of forming a color filter array element comprising: a) imagewise-heating a dye-donor element comprising a support having thereon a dye layer; b) transferring portions of the dye layer to a dye-receiving element comprising a support having thereon a polymeric dye image-receiving layer, the imagewise-heating being done in such a way as to produce a repeating pattern of colorants forming a color filter array, c) coating the color filter array with a polyvinyl alcohol layer; d) coating the polyvinyl alcohol layer with a polymeric barrier layer such as a dye image-receiving layer; and e) heating the color filter array to further diffuse the dye into the dye image-receiving layer.
