Title: Liquid developer for electrostatic photography
Inventor: KATOU EIICHI
IPC: G03G9/13
Filed: 1984-02-28
Abstract: PURPOSE:To provide superior liquid developer capable of giving good continuous gradation and superior image quality and not causing deterioration of image quality, such as lowering of density, dropout of thin lines, and increase of fog, even in successive uses for a long time by incorporating a copolymer having a maleic half amide component and a maleimide component as repeating units in a nonaqueous solvent. CONSTITUTION:A nonaqueous solvent usable here is, preferably, straight or branched aliphatic hydrocarbons, alicyclic hydrocarbons, aromatic hydrocarbons, and halogenated hydrocarbons, etc., having a resistivity of >=10<9>OMEGA.cm and a dielectric constant of <=3.5. A copolymer having maleic half amide component and a maleimide component can be easily prepared by reacting the maleic anhydride component of the polymer with a primary amine compd. of general formula I (R1 is an aliphatic, alicyclic, aromatic, or heterocyclic group) to form a maleic half amide copolymer, and further converting a part of maleic half amide component into a maleimide component. A liquid developer using this compd. can be enhanced in cycles usable for development remarkably, and change of performance is observed very little even in long term storage.
