摘要:
A liquid developer for electrostatic photography is described, comprising at least a resin dispersed in a non-aqueous solvent having an electric resistance of at least 10.sup.9 ohms.cm and a dielectric constant of not more than 3.5. The resin is a copolymer resin obtained by polymerizing a solution containing at least one monofunctional monomer (A) which is soluble in the non-aqueous solvent but becomes insoluble upon polymerization and at least one specified monomer (B) containing an aliphatic group having at least 8 carbon atoms and being copolymerizable with the monomer (A), in the presense of a resin not containing a grafting group polymerizable with the monomers and being soluble in the non-aqueous solvent. The resin may be colored by dissolving at least one organic dye in the dispersion of the resin and heating the mixture. The developer has excellent dispersion stability, redispersibility, fixability and preservability.
摘要:
An electrophotographic lithographic printing plate precursor is disclosed, comprising a conductive support having provided thereon at least one photoconductive layer containing photoconductive zinc oxide and a resin binder, wherein said resin binder comprises a resin containing at least one functional group capable of forming a carboxylic acid upon being decomposed. The printing plate precursor forms an image faithful to an original and causes no background stains because of improved oil-insensitivity of non-image areas, and a printing plate obtained therefrom exhibits high stain resistance and printing durability.
