A method of making a color filter array on a first substrate comprising the steps of: providing at least one transferable colorant layer on a second substrate and positioning such transferable layers in transferable relationship with but spaced a distance from the first substrate; and heating the second substrate sufficiently to simultaneously transfer the colorant materials from the heat transferable colorant layers to the first substrate. An etch process is used to form openings in the first colorant, into which subsequent colorants are deposited.

A method of making a color filter array on a first substrate comprising the steps of: providing at least one transferable colorant layer on a second substrate and positioning such transferable layers in transferable relationship with but spaced a distance from the first substrate; and heating the second substrate sufficiently to simultaneously transfer the colorant materials from the heat transferable colorant layers to the first substrate. Unwanted colorant is then removed by a lift-off process, by chemical mechanical polishing, or by etching, leaving behind the colorant materials in the position of the openings over selected regions.

A method of making a color filter array of uniformly thick organic pigments on a first substrate includes coating an adhesion promoting layer over the first substrate; coating the adhesion promoting layer with an intermediate layer; coating the intermediate layer with a photoresist layer; and exposing and developing the photoresist layer to form an-array of first openings. The substrate further includes etching the intermediate layer, using the photoresist layer as a mask, to form an array of second openings in the intermediate layer which are wider than the corresponding first openings in the photoresist layer; depositing an organic pigment layer on the photoresist layer; lifting off the photoresist layer and overlying organic pigment layer; and removing the intermediate layer, leaving the organic pigment layer in the position of the second openings.

A stabilized storage phosphor is disclosed intended to be exposed to X-radiation and subsequently stimulated to emit light is disclosed. The storage phosphor is the product of firing a combination of species characterized by the relationship:

Stabilized storage phosphors and radiographic screens

A radiographic phosphor panel having binder compatible oxosulfur stabilizer and a preparation method. The phosphor panel has a support and a luminescent layer overlaying the support. The luminescent layer includes phosphor crystals, binder and an oxosulfur reducing agent. The oxosulfur reducing agent is dispersed within the luminescent layer on a substantially molecular basis. The oxosulfur reducing agent is a reducing agent for iodine. The oxosulfur reducing agent has a concentration sufficient to substantially increase the photostimulated luminescence of the panel.
