    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： 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 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.

    摘要： A high contrast and brightness fluorescent screen of a color picture tube has a light absorbing layer in the form of fine dots or stripes provided for the inner surface of a panel of the tube on which the phosphor layer is formed, and a light reflection layer provided at an interface between the light absorbing layer and the phosphor layer. To manufacture the fluorescent screen, a photosensitive resin layer coated on an inner surface of the panel is exposed to light through a photomask mounted on outside of the panel to form a pattern. Nonluminous light absorbing substance is applied on the pattern to form the light absorbing layers.

    摘要： An anti-reflection film is produced on the panel surface of a cathode-ray tube by:(A) preparing a solution for forming an anti-reflection film, which contains water and a metal alkoxide having the formula,M(OR).sub.nwherein M is a metal selected from the group consisting of Si, Ti, Al, Zr, Sn, In, Sb and Zn; R is an alkyl group having 1-10 carbon atoms; n is an integer of from 1 to 8; and when n is not 1, the alkyl groups represented by R may be the same or different,(B) coating the solution for forming an anti-reflection film on the outermost surface of the panel of a cathode-ray tube, and(C) applying an ultraviolet light to the solution for forming an anti-reflection film coated on said surface to cure the solution to form a transparent film with fine roughness.This production method is carried out using an apparatus having:(a) a coating means for coating the above solution for forming an anti-reflection film on the outermost surface of the panel of a cathode-ray tube,(b) a transferring means for transferring the solution-coated cathode-ray tube, and(c) an ultraviolet light-applying means for photocuring the solution coated on the cathode-ray tube during the transfer of the solution-coated cathode-ray tube.In the above method, when a silicon alkoxide is used as the metal alkoxide, there can be obtained a cathode-ray tube having an anti-reflection film made of alkali-free silica on the outermost surface of the panel, said anti-reflection film giving a ratio of Si-O-Si peak intensity to Si-OH peak intensity of 4 or more when measured for infrared spectrum.
