ている。The fluorescent surface for reverse summer limb blood color cathode ray tubes is the glass plate (hereinafter referred to as substrate (2)) on the face of the glass bulb (1) as shown in Figure 2.
), as shown in Figure 3, phosphor layers (R), (G), and (B) emitting the three primary colors of red, green, and blue are formed in a stripe shape, and further phosphor layers of each color (R ) (G) Form a black carbon layer (3) so as to fill the space between (B),
Color mixing between adjacent phosphor layers (R), (G), and (B) is prevented.

収することによって起こる。First, as shown in FIG. 4, a photosensitive adhesive layer (4) made of diazonium metal salt or the like is deposited on a substrate (2). This is done by supplying a photosensitive adhesive to the center of the inner surface of the face of a glass bulb (1), rotating the bulb (1) using an appropriate means to spread it uniformly around the circumference, and then heating it. This is done by drying. Next, as shown in FIG. 5, the portions (4R) where a phosphor layer (R) of one color (for example, red) is to be deposited are selectively exposed.
Adhesiveness is developed only in that area. This adhesiveness occurs when the diazo component in the diazonium metal salt is decomposed by light and zinc chloride is precipitated, which becomes hygroscopic and absorbs moisture from the air.

This is done by sprinkling carbon powder over the entire surface, allowing it to adhere to the area, and then blowing away the carbon powder.

する問題があった。(°. In the process of forming the carbon layer (3) described above, the substrate (2)
The carbon powder sprinkled on the substrate (2) has high cohesion and tends to form lumps, making it difficult to spread over the surface of the substrate (2), making it difficult to form a homogeneous carbon layer. In addition to the fluorescent part, the phosphor particles (5) (5) of the previously formed phosphor layer (R) (G>CB)...
There was a problem that carbon particles (6) (6), etc. easily entered between the spaces between the two, and once they entered, it was difficult to remove them, inhibiting the color development of the phosphor.

... have a particle size of about 3 to 10 μm, whereas carbon particles (6) (6)... have a small diameter of about 1 μm, and phosphor particles (5) (5)... It is easy for carbon particles (6) to enter the gaps between... and the already formed phosphor layer (R) (C;) (B) has a stepped shape, which prevents the carbon particles from entering. (6) (6)・-・
This may be due to the fact that it is difficult for the liquid to flow over the substrate (2).
