Abstract

본 발명은 도전성 미립자의 알콜 분산액을 유리 패널상에 코팅하여 하부층을 형성한 다음, Si-알콜사이드에 굴절율이 낮으면서도 도전성을 띄는 도전성 고분자 화합물을 첨가한 코팅 조성물을 상기 하부층 상에 코팅하여 상부층을 형성하는 단계로 이루어진 다층 코팅막을 갖는 음극선관의 제조방법에 관한 것이다. 본 발명의 음극선관 제조방법에 따라 제조된 다층 코팅막을 갖는 음극선관은 종래의 음극선관에 비하여 외광반사 방지 및 표면저항 특성이 개선되었다.According to the present invention, an alcohol dispersion of conductive fine particles is coated on a glass panel to form a lower layer, and then an upper layer is coated on the lower layer by coating a coating composition containing a conductive polymer compound having low refractive index and high conductivity to Si-alcohol. It relates to a method for producing a cathode ray tube having a multi-layer coating film made of a step. The cathode ray tube having a multilayer coating film prepared according to the cathode ray tube manufacturing method of the present invention has improved external light reflection prevention and surface resistance characteristics as compared to the conventional cathode ray tube.
