摘要：
A minute-particle iron oxide red pigment slurry is formed by adding sodium silicate to a minute-particle iron oxide red pigment slurry, and used to form a red filter formed between a phosphor layer of a color cathode ray tube and a panel thereof. Therefore, even if the red filter is brought in contact with a black matrix under the condition of a process of manufacturing the color cathode ray tube at high temperature, the red filter does not discolor the black matrix.
