ABSTRACT:
A 1,1,4,4-tetraphenyl-1,3-butadiene derivatives represented by formula (I): ##STR1## wherein R.sub.1 represents a di-lower alkylamino group, and R.sub.2 represents a hydrogen atom or a di-lower alkylamino group, is disclosed, which has useful characteristics such as excellent static charge retention ability. An electrophotographic light-sensitive material using the foregoing derivative can satisfy the requirements, e.g., for high sensitivity, low residual potential, less light fatigue even after repeated use, and excellent durability.
