Abstract
Photoconductive compositions having improved quantum efficiency are disclosed. The compositions comprise: PA1 (a) an electron donating photoconductor; and sensitizing amounts of PA1 (b) a first electron acceptor selected from cyanine and styryl methine dyes having a 1,3,2-dioxaborin nucleus and PA1 (c) a second electron acceptor selected from methine-free compounds having a nucleus selected from the group consisting of 1,3,2-dioxaborin; 1,3,2-oxazoborin and 1,3,2-diazoborins.
