DEFINITION

Classification: 430/59.3

Compound having an acyclic azo group and having either an azomethine (i.e., -CH=N) or a stilbene group; or a compound having three or more azo groups in charge generator layer:

(under subclass 59.2) Subject matter wherein the azo compound of the charge generator layer has at least three azo groups, or azomethine group, i.e., N=CH -, or a stilbene group (i.e.-Ph-CR=CR-Ph- wherein Ph is a phenylene group).
