ABSTRACT:
A liquid composition for development of latent electrostatic images formed on an offset master for use in the production of multiple copies by offset duplication, in which the developer composition is formulated to contain a fatty acid amine, aromatic amine, heterocyclic amine or other aliphatic amine containing from 3 to 18 carbon atoms in the aliphatic group to obviate the undesirable effects from treatment of the imaged surface with a conversion solution.
