摘要:
The present invention discloses a decolorizable toner wherein a cationic dye having absorbance from the visible region to the near infrared region is contained in a binder resin together with a decolorant and anti-discoloration agent. In addition, the present invention also discloses a production process of a decolorizable toner that contains a step wherein cationic dye having absorbance from the visible region to the near infrared region, decolorant, binder resin and anti-discoloration agent are uniformly dissolved or dispersed in an organic solvent to prepare a mixed solution; a step wherein the solvent is removed from this mixed solution followed by drying; and, a step wherein the resulting dried mixture is pulverized to produce a toner.
