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 a positive phototackifiable polyacetylene 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 tackify the exposed areas. The exposed areas are then contacted with a pigment or phosphor which is desired to be applied to the exposed area and it selectively adheres to the exposed areas. The exposure and dusting are repeated for each application of different color pigments, toners or phosphors.
