主权项

1. A charge transport layer, which is a film that is formed by applying a composition so as to form a coated composition and heating the coated composition;
wherein the composition comprises: (B) an arylamine derivative having at least two polymerizable groups represented by the following formula (1) or formula (2): wherein each of R1 and R1′ independently represents a polymerizable group; and each of R2, and R2′independently represents a hydrogen atom or a substituent: wherein each of R and R′independently represents a polymerizable group; and (A) a cyano group-free azo based polymerization initiator represented by the following formula (PI): wherein each of RPI1and RPI2 independently represents an alkyl group or an aryl group; RPI3represents —C(═O)—O—RPI4, —O—C(═O)—RPI4, or —C(═)—NH—RPI4; and RPI4 represents an alkyl group or a cycloalkyl group.
