Abstract

안료부착 형광체의 제조시, 경화 오정과, 세정 공정 사이에 초산을 첨가하여 pH를 pH6∼7로 조절시키는 중화공정을 둔 안료부착 형광체의 제조방법으로서, 감광재인 폴리비닐 알콜의 겔화를 방지하고, 안료부착 형광체를 사용하여 제조한 칼라 브라운관의 색잔 및 스트라이프의 탈락현상을 방지할 수 있다.A method for producing a pigmented phosphor with a neutralization step in which a pH is adjusted to pH 6-7 by adding acetic acid between the curing well and the washing process during the production of the pigmented phosphor, preventing gelation of polyvinyl alcohol as a photosensitive material, It is possible to prevent the dropping of the color cup and stripe of the color CRT manufactured using the pigment-containing phosphor.
