The present invention provides an electrolytic solution for aluminum electrolytic capacitors which has a high sparking voltage while maintaining its specific conductivity at 30&#xb0; C. of 4 to 25 mS/cm and which has no possibility of corroding capacitor elements, and an aluminum electrolytic capacitor using the same. The electrolytic solution of the present invention is characterized as being an electrolytic solution containing an electrolyte (C) composed of an alkyl phosphate anion (A) represented by formula (1) or (2) given below and a cation (B), and an organic solvent (D), wherein the content of phosphoric acid in the electrolytic solution is 1% by weight or less: wherein Ris an alkyl group having 1 to 10 carbon atoms and Ris a hydrogen atom or an alkyl group having 1 to 10 carbon atoms.

Electrolytic solution for aluminum electrolytic capacitors, and aluminum electrolytic capacitor using the same

A toner with a glass transition point (Tg) before curing of not lower than 35&deg; C., said toner comprising: a toner binder composed of a resin (I) selected from the group consisting of a cation-polymerizable thermoplastic resin (A) and a radical-polymerizable thermoplastic resin (B); and a colorant. The resins making up the toner binder are polymerizable ones and are cured in fixing the image on the support so that the number average molecular weight can be increased after the fixing step. That is, a toner binder with a low number average molecular weight can be used, and fixed at a low temperature and with low energy. Because of the low number average molecular weight, the toner is low in viscosity and excellent in gloss development and can produce high-quality multi-color images. Since the toner polymerizes and cures to increase in number average molecular weight while fixing, the hot offset is hardly caused, with a high fixing strength and an excellent wear resistance developed.
