    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: A water-soluble, positive-working photoresist composition is disclosed which comprises water-soluble aromatic diazonium salt, water-soluble phenolic compound, and water-soluble polymeric compound. When the film of this composition is irradiated with a pattern of actinic ray and then brought into contact with an alkaline gas or solution, the coating of unexposed areas hardens to become water-insoluble. Preferably, when the film is brought into contact with a suspension of powder or dry powder after being hardened, a positive pattern of powder is obtained by the development with water.

    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.
