Abstract

본 발명은 라-카 필름 형성전에 사용하는 전처리액의 조성물에 폴리아크릴산을 첨가하여 분산성을 향상시켜 막 얼룩을 줄이고 휘도를 향상시키는 칼라브라운관의 라-카 전처리액에 관한것으로, 브라운관의 형광막에 알루미늄을 증착하기 위한 라-카막 형성시 형광체면을 적셔주는 전처리액의 조성에 있어서, 전처리액에 폴리아크릴산이 함유된 것임을 특징으로 하는 칼라브라운관의 라-카(Lacquer) 전처리액의 조성물에 관한 기술임.The present invention relates to a La-car pretreatment solution of a color-brown tube which improves dispersibility by adding polyacrylic acid to a composition of a pretreatment solution used before the formation of a la-car film, thereby improving luminance. Regarding the composition of a Lacquer pretreatment liquid of a color-brown tube, wherein the pretreatment liquid contains polyacrylic acid in the composition of the pretreatment solution that wets the phosphor surface when forming a la-caramel for depositing aluminum on Technology.
