DEFINITION

Classification: 430/58.7

Polymeric arylamine containing:

(under subclass 58.65) Subject matter wherein the charge transport layer contains an arylamine polymer, i.e., a long chain structure with repeating units that include an arylamine grouping, e.g., included in this subclass are polymers having multiple arylamine side groups attached to a polymeric backbone, and polymers having arylamines in the backbone.
