ABSTRACT:
A method for the manufacture of multi-colored microlithographic displays especially fluorescent screens for cathode ray tubes is provided in which a film of an olefin sulfone polymer is applied to the substrate of the display. The film is then exposed in predetermined areas with a sufficient amount of radiation to depolymerize and lower the melting point of the polymer in the exposed areas. The film is then heated to a temperature above the softening point of the exposed polymer but below the softening point of unexposed polymer and contacted with the pigment or phosphor which is desired to be applied which selectively adheres to the exposed areas. The exposure and dusting are repeated for each application of different color pigments, toners or phosphors.
