    摘要： In a method of forming a fluorescent screen of a color picture tube by a dry process, the method comprises a first step of precoating an emulsion containing a powder of acryl resin on an inner surface of a face plate of the color picture tube to form a primary coating, a second step of coating on the primary coating a photosensitive composition consisting essentially of a diazonium salt to form a thin film, a third step of exposing to light a selected portion of the thin film to render the same to become adhesive, a fourth step of depositing a powder of a phosphor on the selected portion to form a phosphor layer of a first color and a fifth step of repeating the third and fourth steps to form phosphor layers of second and third colors.

    摘要： In a phosphor screen of cathode ray tube produced by forming a lacquer film between phosphor layers and a metallic film, when the lacquer film is formed by using a composition comprising a resin component, an organic solvent and a plasticizer in an amount of about 12 to 60% by weight based on the weight of the resin component, the resulting phosphor screen is excellent in adhesive strength of the metallic film and can prevent color mixing and halation.

    摘要： A method of forming a color picture tube fluorescent screen by so-called dry process. After a photosticky substance mainly containing a diazonium compound is coated on a panel inner face, phosphor is adhered to portions of the compound which have been exposed to light through a color selection electrode and rendered sticky, and surplus phosphor applied on unexposed portions of the compound is removed, the above steps being consecutively repeated for phosphors of three colors to form picture elements of triads of three color phosphors on the panel inner face. The panel inner face is then treated with an aqueous solution containing at least polymer coagulant.

    摘要： In a method of forming a fluorescent screen on the inner surface of a face plate of a color picture tube wherein a film of photosensitive composition consisting essentially of a diazonium salt, the portions of the films to be deposited with phosphors are exposed to light through a color selection electrode so as to impart sticky property to the portions by a photoreaction and moisture in atmosphere and then a powder of phosphors is deposited by utilizing the sticky property, a photosensitive binder is incorporated into photosensitive film which undergoes a cross-linkage reaction with the photosensitive composition, thus rendering the mixture insoluble in water.

    摘要： In forming a fluorescent screen for a color picture tube having triads of phosphor materials of the three primary colors arranged in a predetermined pattern on the inner surface of a panel, a photosensitive film which exhibits stickiness when exposed to a threshold amount of light is formed on the inner surface of the panel. Locations of the photosensitive film where the three color phosphor materials respectively occupy are exposed to light from a light source through a shadow mask mounted to the panel. The amount of exposure light for a first color phosphor material is the threshold or above and that for second and third phosphor materials is below the threshold. After completion of the light exposures for the first to third color phosphor materials through the shadow mask, the shadow mask is dismounted from the panel and the first color phosphor material is deposited onto the photosensitive film. A first back exposure is then carried out and the second color phosphor material is deposited onto the photosensitive film. Thereafter, a second back exposure is carried out and the third color phosphor material is deposited onto the photosensitive film.
