Multiple-use color thermal transfer printing ribbon

Multiple-use color thermal transfer printing ribbon. (Nippon Telegraph and Telephone Public Corp., Japan). Jpn. Kokai Tokkyo Koho JP 58188690 A2 4 Nov 1983 Showa, 7 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B41M005-26; B41J031-00. APPLICATION: JP 82-71324 30 Apr 1982. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 74 A substrate having a finely porous structure for ink-holding layers is coated with heat-sensitive transfer printing inks having different colors (yellow, cyan, magenta, and optionally black) to prep. a ribbon. Thus, Eslec (vinyl acetate-vinyl chloride copolymer) [9003-22-9] 20, Bu cellosolve 10, MEK 40, and a following ink 30 parts were ball milled, coated on a polyester film, and dried to prep. a ribbon. A yellow ink contained Benzidine Yellow [6358-85-6]-Oramine base [492-80-8]. A cyan ink contained milori blue [14038-43-8]-Victoria Blue Base [6786-83-0]. A magenta ink contained Lake Red [69344-93-0]-Rhodamine Base [509-34-2]. The ribbon gave clear letters after ~10 printings and readable letters after ~20 printings.

DOCUMENT TYPE: Journal CA Section: 25 (Noncondensed Aromatic Compounds) Section cross-reference(s): 23 Cl3CCHO reacted with RCR1:NH [R = R1 = Ph, p-Me2NC6H4; R = EtO, R1 = Me, Ph, CH2CN, CH2C(:NH)OEt; R = Ph, R1 = NH2; R = Me, R1 = NHPh] in hexane or Et2O to give 68-76% RCR1:NCH(OH)CCl3 (I). I were cleaved to the starting materials with dry HCl. ..
