Abstract
Styrene-acrylic copolymer is used as an organic binder, fluorenone derivative is used as an electron receptor and tetraphenylbutadiene derivative is used as an electron donor to produce a color display panel which has a low decomposition temperature, a high electron transferring ability and a charge maintenance ability to manufacture a color display panel without a change of brightness and color coordinates in a fluorescent screen.
Claims6
A composition of a photoconductive layer for a color display panel comprising:
- styrene acrylic copolymer as an organic binder expressed as formula 1 below;
- fluorenone derivative as an electron acceptor expressed as formula 2 below;
- tetraphenyl butadiene derivative as an electron donor expressed as formula 3 below;
- and
- a solvent ##STR2## wherein, R.sub.1 and R.sub.2 are independently hydrogen or an alkyl group, R.sub.3 is an alkyl group or an alkylene group and X is a polar group, and l, m and n may change for control of the concentration of a photoconductive material and surface charge, R.sub.4 is a carbonyl group substituted with an alkyl group, an alkoxy group or an aryl group, R.sub.5 is selected from the group consisting of hydrogen, halogen, alkyl group, alkoxy group, cyano group, nitro group, ester group and trifluoromethyl group, and R.sub.6 is a dimethylamine group or a methoxy group and R.sub.7 is hydrogen, a methoxy or dimethylamine group.
A fluorenone derivative as an electron acceptor for a photoconductive layer of a color display panel expressed as formula 2.
