摘要：
An electrophotographic liquid developer is disclosed. The developer is comprised of resin particles dispersed in a high-insulating low dielectric non-aqueous solvent. The resin particles are prepared by polymerizing or copolymerizing a specific styrenic monomer in an organic solvent containing a polymer which is substantially soluble in the organic solvent. The liquid developer is particularly suitable for making a printing plate or sheet by an electrophotographic process.
