摘要:
A paint composition includes a raw polymer, and a dry solvent for dissolving the raw polymer. The raw polymer is composed of a transparent polymer having a hydroxyl group, and polysilazane. The polysilazane is included in an amount of 10% by weight or more with respect to the entire raw polymer taken as 100% by weight. Also disclosed are a process for producing a transparent protective film using the paint composition, and organic glass using the same. Note that the organic glass exhibits a surface hardness of 0.4 GPa or more.

A method for manufacturing a phosphor screen is disclosed, which includes the steps of coating a photo-sensitive phosphor paste on a necessary portion, exposing the coated photo-sensitive phosphor paste through a photo-mask, and developing the exposed phosphor paste thereby to form a phosphor stripe. Also, a photo-sensitive phosphor paste is disclosed, in which at least one glycol selected from glycol groups of 1, 2-propanediol, 1, 3-propanediol, 1, 3-butanediol, 2-methyl-2, 4-pentanediol and so on is contained with a weight ratio of 0.1 to 2.0 relative to a solid component of polyvinyl alcohol.
摘要:
A beam-index type color cathode ray tube device which includes a front panel portion, a screen panel portion which faces the front panel portion, a phosphor screen including a plurality of index phosphor stripes fixed to the inner surface of the screen panel portion and extending at regularly spaced intervals. A porous inorganic layer is fixed on the inner surface of the screen panel portion and extends between each adjoining pair of the index phosphor stripes. A metallic reflecting layer covers the index phosphor stripes and the porous inorganic layer. A plurality of color phosphor stripes is applied to the metallic reflecting layer in a predetermined pattern. A photodetecting portion disposed at the outside of the screen panel portion receives fluorescence from the actuation of the index phosphor stripes.
