Inks for ink-type wire-dot printers

Inks for ink-type wire-dot printers. (Pentel Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58160376 A2 22 Sep 1983 Showa, 6 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C09D011-08. APPLICATION: JP 82-43214 18 Mar 1982. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) The title inks are composed of water-sol. dye(s); water-sol. org. solvent(s); water; 31 compd(s). 9004-62-0 and 9004-67-5 which are cas registry numbers are also used here. selected from methyl cellulose [9004-67-5], hydroxyethyl cellulose [9004-62-0], hydroxypropyl cellulose (I) [9004-64-2], ethyl hydroxyethyl cellulose [9004-58-4], hydroxypropyl Me cellulose [9004-65-3], and urea [57-13-6] [or urea derivs.]; the viscosity, surface tension, and pH of the inks are 3-12 cP, 332 dyne/cm, and 7-10, resp. The inks are difficult to dry at the printing head of a wire-dot printer and give smooth initial printings after prolonged shutdown. Thus, C.I. Direct Black 19, C.I. Acid Red 87, C.I. Acid Yellow 42, ethylene glycol, thiodiethanol, ethyleneurea [120-93-4], I, and water were mixed and filtered to yield a black ink having viscosity 8.2 cP (25°), surface tension 47.0 dyne/cm, pH 9.8, which gave initial printings of good quality after a 3-day shutdown. .

Water-washable remover for disperse varnishes. Drobny, Frantisek; Kovacikova, Eleonora (Czech. ). Czech. CS 210847 B 15 Sep 1983,4 pp. (Slovak). (Czechoslovakia). CODEN: CZXXA9. CLASS: IC: C09D009-00. APPLICATION: CS 79-4360 26 Jun 1979. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) The described thixotropic compn. swells coatings of disperse varnishes so that they can be removed by rinsing with water. It consists of CH2Cl2 [75-09-2] 5095, paraffin (m.p. 50-4°) 0.1-3, C1-3-alkyl hydroxyalkyl cellulose 0.1-10, C1-3 alc. 4-30, xylene [1330-20-7] 0.5-10, polyglycol ether of stearic acid (I) (m.p. 35-45°) 0.1-5, oxyethylated stearic ester (II) contg. 45-55% oxirane 0.1-5, BzONa [532-32-1] <1, C2-3-alkyl polyglycol phosphate neutralized with HOCH2CH2NH2 <3, and aq. NH3 <0.5 parts. An exemplary remover of coatings from building facades comprised Et hydroxylethyl cellulose [9004-58-4] 1, CH2Cl2 80, EtOH [64-17-5] 6, xylene 9, aq. NH3 0.1, I 0.2, II 0. 57-11-4 and 9004-65-3 are just another two chemicals used in this study.6, paraffin 3, and BzONa 0.1 parts. .
