Abstract:
A decolorable toner comprising a dye capable of absorbing visible rays to near-infrared rays, a decoloring agent and a binder resin as the principal components. A binder resin (A) blended with the light-absorbing dye is dispersed in a binder resin B, and a decoloring agent is blended with the binder resins A and/or B. The present invention provides also a method of producing such a toner. The decolorable toner can quickly decolor its color by the exposure to visible rays or near-infrared rays. According to the production method of the present invention, the charge quantity by a chargeable material can easily be adjusted, and the dye does not easily fade during the kneading in the production of the toner.
Abstract:
A composite metal material (1), used, e.g., as an electrolytic capacitor electrode-use material, comprising a polymer thin film (11) formed by self-organizing on at least one surface of a metal material substrate (10) and having fine patterns (12). This polymer thin film (11) is formed, for example, by drying the hydrophobic organic solvent solution of a polymer compound. Etching this composite metal material (1) forms etching pits distributed uniformly at high density based on the above fine patterns.
