Abstract This invention relates to organic diselenides and polyselenides among which are cyclic compounds represented by the formula: WHEREIN R is selected from divalent hydrocarbylene radicals of five to 20 carbon atoms, divalent heterocyclic, alicyclic and aromatic radicals having from three to 50 carbon atoms, n is a positive integer and X is the radical - Se - R - Se - ; linear polymers having a repeating unit represented by the formula: - Se - A - Se - II. wherein A is selected from divalent alkylene radicals having from nine to 20 carbon atoms, divalent aromatic radicals from six to 50 carbon atoms and divalent heterocyclic radicals and polymers having a repeating unit represented by the formula: WHEREIN B is selected from the group consisting of divalent hydrocarbylene radicals and divalent heterocyclic radicals, a is a positive integer of at least 3 and b is a positive integer greater than 1. This invention also relates to the use of these compounds in the production of electrophotographic plates.
