COLORED MATERIAL FOR BACK SIDE PLATE OF PLASMA DISPLAY PANEL

PURPOSE: A colored material for the back side plate of a plasma display panel is provided to etch with the velocity capable of ensuring a low temperature plasticity and a productivity and gain a colored material which has a precise structure after a diaphragm is formed by an etching and of which the mechanical intensity and the thermostability are large. CONSTITUTION: A colored material for the back side plate of a plasma display panel is a colored material composed of PbO 43-91wt%, SiO2 21wt% and below, B2O3 26wt% and below, Al2O3 7wt% and below, ZnO 35wt% and below, Na2O+K2O+Li2O 15wt% and below, and BaO+CaO+MgO+SrO 15wt%. Also, the colored material is composed of, at least, one kind or more among glass powders of which the softening temperature is 320-550°C(a coefficient of thermal expansion is 62-110x10-7/°C) and in which th diameter of a particle of the powder is 0.5-17um, and includes an organic material supporting that. 본 발명은 유색재료가 에칭이 가능한 유리분말 또는 에칭이 가능한 유리분말과 필러로 구성되고 연화온도가 다른 2종 이상의 유리분말을 혼합하거나 필러의 양과 종류를 조절하거나 또는 적층구조의 선택으로, 저온소성과 생산성이 확보되는 속도의 에칭이 가능하며, 에칭으로 격벽형성후 치밀한 구조를 가지며 내열성과 기계적 강도가 큰 유색재료를 얻는 플라즈마 디스플레이 패널 후면판용 유색재료에 관한 것이다.
