| 摘要 |
The present invention relates to a liquid developer for electrostatic latent image, comprising the following components (a), (b) and (c) which are dispersed in an electrical resistive aliphatic hydrocarbon solvent: (a) a non-gel copolymer which as a whole is insoluble in the solvent and which consists essentially of a copolymer segment soluble in the solvent and a polymer segment insoluble in the solvent, the solvent-soluble copolymer segment containing as main monomer components an alkyl acrylate or an alkyl methacrylate and a cycloalkyl acrylate or a cyckloalkyl methacrylate and/or an aralkyl acrylate or an aralkyl methacrylate, and the solvent-insoluble polymer segment containing vinyl acetate as a main monomer component; (b) a coloring agent; and (c) a dispersant. The liquid developer for electrostatic latent image of the present invention does not change in print density and is used effectively in electrophotography, for example, in wet copier and printer, and in electrostatography, for example, in facsimile and electrostatic plotter. Particularly, it is suitable for multicolor printing.
