摘要： PURPOSE:To provide an electrostatic charge image developing toner excellent in light resistance and color-erasing property by allowing the mixtures of coloring toner particles into which a near infrared absorbing dye is compounded and sensitizer toner particles into which a color erasing agent is compounded to be present independently from each other. CONSTITUTION:This toner consists of coloring toner particles into which a near infrared absorbing dye expressed by formula I or formula II is compounded, and sensitizer toner particles into which a color erasing agent expressed by formula III is compounded. During developing and fixing, both toner particles are uniformly dispersed with a small frequency of contact of both toner particles so that the toner has excellent light resistance and storage stability. During erasing, the toner is heated to increase fluidity of the binder resin and to increase the frequency of contact of both toner particles, which improves the color erasing rate. In formulae, X is a halogen ion, etc., R -R are hydrogen, univalent hydroxyl groups, etc., Y is a cation, R -R are alkyl groups, aryl groups, etc., and R -R are hydrogen atoms, alkyl groups, etc.

摘要： PURPOSE:To provide a toner excellent in resistance against yellowing which can be erased with irradiation of near infrared rays by incorporating a specified dye which absorbs near infrared rays, decolorizing agent, and UV absorbent. CONSTITUTION:This toner contains a binder resin, dye which absorbs near infrared rays expressed by formula I or II, and decolorizing agent expressed by formula III. Further, an UV absorbent is incorporated by 0.2-30 pts.wt. to 100 pts.wt. of the binder resin. In formulae I-III, X is halogen ion, perchloric ion, etc., R -R are hydrogen atoms, hydrocarbon groups, etc., Y is cation having absorption characteristics in a near infrared region, R -R are alkyl groups, aryl groups, and at least one of them is an alkyl group of 1-12 carbon number, R -R are hydrogen atoms, alkyl groups, etc. When the process to form letters or pictures with this toner on a image supporting body such as copy paper and to erase the letters or pictures is repeated, the letters and images can be erased but give no decolorization to the supporting body so that the supporting body can be repeatedly used.

摘要： PURPOSE:To facilitate the control of the extent of electrostatic charge of a decolorable toner and to prevent the fading of a dye due to kneading at the time of production of the toner by dispersing a bonding resin blended with a visible radiation-near IR absorbing dye in a bonding resin and blending one of the resins with a decoloring agent. CONSTITUTION:A bonding resin (A) blended with a visible radiationnear IR absorbing dye is dispersed in a bonding resin (B) and one of the resins A and B is blended with a decoloring agent. When the extent of electrostatic charge of the resultant decolorable toner is controlled by blending the resin B with an electrostatic charge controlling agent, the control is facilitated because the controlling agent is hardly affected by the high positive chargeability of the dye. In the case where resins incompatible with each other are used as the resins A and B, they are dispersed in a sea-island structure at the time of melting by heating and kneading but the high positive chargeability of the dye is hardly exhibited at the surface because of incompatibility.

摘要： PURPOSE:To substantially eliminate the adverse influence of decoloration and color fading even when the decoloration type toner is heated at the time of kneading or is irradiated with natural light during storage by incorporating a binder resin and specific near IR absorptive dye into the toner. CONSTITUTION:The binder resin and the near IR absorptive dye into the toner expressed by formula I or formula II are incorporated into the decoloration type toner. In the formula I, X denotes halogen ions, perchloric acid ions, PF6 SbF6 , OH , sulfonic acid ions or BF4 ; Y denotes a cation having an absorption characteristic in a near IR region. In the formula II, R to R respectively independently denote hydrogen atoms, hydrocarbon groups or hydrocarbon groups contg. heteroatoms ; Y is the same as in the case of the formula I. Namely, the binder resin and the near IR absorptive dye are used for the master batch for the decoloration toner and decoloring agents are not incorporated therein and, therefore, the master batch itself is excellent in optical stability, etc., and exhibits the color fading resistance excellent over a long period.
