NEW MATERIAL:A quinone compound shown by the formula I [R1 is H, alkyl orakoxy; R2 and R3 are H or R2 and R3 are bonded to form condensed cyclic group shown by the formula II (R4 is H or halogen; n is 0 or 1W4); X is H or halogen (when R2 and R3 are group shown by the formula II, R1 is alkyl or alkoxy)].

USE: A coloring material for high polymer, coloring material for liquid crystal, electrophotographic sensitized material for electrophotographic printer or a material for infrared cutting filter or laser writing liquid crystal display.

PREPARATION: For example, a compound shown by the formula III is reacted with a compound shown by the formula IV in a solvent such as methanol, dichlorobenzene, etc., at -10W150°C to give a compound shown by the formula I.
