*Required Fields

Toner for imaging processes: Toner for imaging processes. (Canon K. K., Japan). Jpn. Kokai Tokkyo Koho JP 57201248 A2 9 Dec 1982 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: G03G009-08. 19715-19-6 and 7440-47-3 which are cas registry numbers are also used here. APPLICATION: JP 81-87180 5 Jun 1981. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) A toner is prepd. by the melt-spraying of a compn. contg. 330 wt.% of a polyethylene wax with a melt viscosity at 140° of 10-60 cP. Thus, polyethylene wax (viscosity 70 cP) 100, magnetite 60, and Cr di-tert-butylsalicylate 4 parts were mixed at 150° and then sprayed to give an electrostatog. magnetic toner with excellent flow characteristics. .

Pressure-fixable toners: Pressure-fixable toners. (Canon K. K., Japan). Jpn. Kokai Tokkyo Koho JP 57201250 A2 9 Dec 1982 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: G03G009-08; B01D001-18. APPLICATION: JP 81-87182 5 Jun 1981. 19715-19-6 and 1309-38-2 which are cas registry numbers are also used here. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Toner compns. contg. a coloring agent and a thermoplastic resin are melt-sprayed into a hot gas flow having the appropriate temp. gradient so as to give a spherical toner. The resultant pressure-fixable spherical toner exhibits good flow characteristics. Thus, a mixt. of polyethylene, Fe3O4, and Cr di-tert-butylsalicylate was melt-sprayed into a hot air flow (the temps. at the entrance and exit are 100° and 50°, resp.) to give a spherical magnetic toner. .
