Patent ID: 7060405

Claim:
A naphthoquinone derivative represented by Formula 1: wherein: R 1 is selected from the group consisting of a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 carbon atoms, and a substituted or unsubstituted aralkyl group having 7 to 30 carbon atoms; R 2 is selected from the group consisting of an alkylene group having 2 to 20 carbon atoms, an arylene group having 6 to 30 carbon atoms, and an arylene-alkylene group having 7 to 30 carbon atoms; n is 1; and R 3 is selected from the group consisting of a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 carbon atoms, a substituted or unsubstituted aralkyl group having 7 to 30 carbon atoms, and a group represented by Formula 1a or 1b: —R 4 —O—R 7 Formula 1a —R 5 —O—R 6 —O—R 7 Formula 1b wherein: R 4 , R 5 , and R 6 are selected from the group consisting of, independently, an alkylene group having 2 to 20 carbon atoms, an arylene group having 6 to 30 carbon atoms, and an arylene-alkylene group having 7 to 30 carbon atoms; and R 7 is selected from the group consisting of a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 carbon atoms, and a substituted or unsubstituted aralkyl group having 7 to 30 carbon atoms.
