<p>A liquid developer for electrostatic photography is disclosed. The liquid developer comprises at least resin grains dispersed in a non-aqueous solvent having an electric resistance of at least 10<9> cm and a dielectric constant of not higher than 3.5, wherein the dispersed resin grains are copolymer resin grains obtained by polymerizing a solution containing (l) at least a mono-functional monomer (A) which is soluble in the above-described non-aqueous solvent but becomes insoluble therein by being polymerized, and, optionally, a monomer (C) represented by the formula (III) or a monomer (D) represented by the formula (IV), in the presence of a dispersion-stabilizing resin soluble in the non-aqueous solvent, which is a graft type copolymer. The liquid developer of the present invention is excellent in re-dispersibility, storability, stability, image-reproducibility, and fixability, and provide a master plate for offset printing having high printing durability.</p> |
