Claim 1

In a method for preparing a mosaic luminescent screen on a glass surface, the steps of A. adhering islands of a dry precoating to said glass surface at the sites of the mosaic parts of said luminescent screen, B. depositing over said islands a dry coating comprising phosphor particles and a photoinsolubilizable binder for said particles, C. photoinsolubilizing defined regions of said coating over said islands D. and then subjecting said photoinsolubilized regions to a turbulent aqueous developing medium.

Claim 10

A method for preparing a mosaic luminescent screen on a glass surface comprising the steps of A. adhering to said glass surface a dry photoinsolubilizable layer of precoating material, B. exposing said layer of precoating material to a pattern of actinic radiation until islands of precoating material at the sites of the mosaic parts of said luminescent screen are insolubilized, C. developing said exposed layer to retain said islands and to remove the remainder of said layer, D. depositing over said islands of precoating material and glass surface a dry coating comprising phosphor particles and a water-soluble, photoinsolubilized binder for said phosphor particles, E. photoinsolubilizing defined regions of said coating over said islands F. and then developing said coating with a turbulent aqueous developing medium.

Claim 11

A method for preparing a mosaic luminescent screen on a glass surface comprising the steps of A. adhering to said glass surface a dry photoinsolubilizable layer of precoating material, B. exposing said layer of precoating material to a pattern of actinic radiation until islands of precoating material at the sites of the mosaic parts of said luminescent screen are insolubilized, C. developing said exposed layer to retain said islands and to remove the remainder of said layer, D. depositing over said islands of precoating material and glass surface a dry coating comprising phosphor particles and a water-soluble, photoinsolubilized binder for said phosphor particles, E. photoinsolubilizing defined regions of said coating over said islands F. and then developing said coating with a turbulent aqueous developing medium.

Claim 20

A method for preparing a mosaic luminescent screen comprising a multiplicity of mosaic parts of at least two different luminescence characteristics on the inner surface of a glass faceplate panel, said panel including a glass viewing window, integral peripheral sidewalls surrounding said window and extending axially from the inner surface of said window, and a plurality of metal mounting studs implanted in said sidewalls and extending outwardly from the inner surface thereof, said method comprising the steps of A. producing on said inner surfaces of said window and said sidewalls a black matrix having openings therein that define the sites of said mosaic parts, B. adhering to said matrix and the exposed inner surface of said window a dry photoinsolubilizable layer of precoating material, C. flooding actinic light through said window and the openings in said matrix until islands of precoating material at said sites are insolubilized, D. developing said exposed precoating layer, retaining said islands of insolubilized material and removing substantially all of the soluble material from said matrix, said sidewalls and said studs, E. depositing on retained islands, mosaic parts comprising phosphor particles having one of said luminescent characteristics and a photoinsolubilized binder therefor, F. subjecting said mosaic parts to a turbulent aqueous developing medium, G. repeating steps E and F for mosaic parts of each other luminescent characteristic, H. depositing over said mosaic parts a specular film of organic polymeric material, I. depositing over said specular film an aluminum metal layer and J. baking said panel and layers thereon in air at temperatures and for times sufficient to gasify organic material in said layers and to permit the gases formed to escape through said metal layer.

Claim 21

A method for preparing a mosaic luminescent screen comprising a multiplicity of mosaic parts of at least two different luminescence characteristics on the inner surface of a glass faceplate panel, said panel including a glass viewing window, integral peripheral sidewalls surrounding said window and extending axially from the inner surface of said window, and a plurality of metal mounting studs implanted in said sidewalls and extending outwardly from the inner surface thereof, said method comprising the steps of A. producing on said inner surfaces of said window and said sidewalls a black matrix having openings therein that define the sites of said mosaic parts, B. adhering to said matrix and the exposed inner surface of said window a dry photoinsolubilizable layer of precoating material, C. flooding actinic light through said window and the openings in said matrix until islands of precoating material at said sites are insolubilized, D. developing said exposed precoating layer, retaining said islands of insolubilized material and removing substantially all of the soluble material from said matrix, said sidewalls and said studs, E. depositing on retained islands, mosaic parts comprising phosphor particles having one of said luminescent characteristics and a photoinsolubilized binder therefor, F. subjecting said mosaic parts to a turbulent aqueous developing medium, G. repeating steps E and F for mosaic parts of each other luminescent characteristic, H. depositing over said mosaic parts a specular film of organic polymeric material, I. depositing over said specular film an aluminum metal layer and J. baking said panel and layers thereon in air at temperatures and for times sufficient to gasify organic material in said layers and to permit the gases formed to escape through said metal layer.
