Abstract: A two-phase lacquer emulsion for treating exposed lithographic plates. An aqueous phase contains a desensitizer and a pyrogenic silica as a thickener, with a surfactant. A nonaqueous phase comprises as its major ingredients a water-insoluble solvent and a water-insoluble oleophilic resin resistant to fountain solutions, inks, weak acids, alcohols, aliphatic hydrocarbons and drying oils. The resin and solvent are homogenized so that the resin particle size lies between 1 and 500 microns. The nonaqueous phase may also include pigment and a nonionic surfactant.
