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) <IMAGE> 1 where R is selected from the group consisting of hydrogen, C1-C10 linear alkyl or branched alkyl, halogen, alkylamino (NR1), alkylester (COOR1) and alpha -cyanomethyl alkylketone (CH(CN)COR2), R1 and R2 being selected from the group consisting of C1-C10 alkyl, aryl, C1-C10 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. |
