ABSTRACT:
A photo-conductive composition and CRT bulb having a photoconductive layer formed of the same are provided. The photo-conductive composition comprises 5-15 wt % of a charge transmitting substance, represented by the structural formula (1) ##STR1## where R is selected from the group consisting of hydrogen, C.sub.1 -C.sub.10 linear alkyl or branched alkyl, halogen, alkylamino (NR.sub.1), alkylester (COOR.sub.1) and .alpha.-cyanomethyl alkylketone (CH(CN)COR.sub.2), R.sub.1 and R.sub.2 being selected from the group consisting of C.sub.1 -C.sub.10 alkyl, aryl, C.sub.1 -C.sub.10 alkoxy and aryloxy, and n is an integer between 500 and 1000;
1-15 wt % of a charge generating substance which absorbs light in the wavelength range of an ultraviolet region;
70-93.95 wt % of a binder; and
0.05-1 wt % of a surfactant. The photo-conductive composition exhibits excellent sintering characteristic and can form a photoconductive layer having excellent sensitivity, durability and luminance.
