Multicolor thermal recording media. (Ricoh Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59001295 A2 6 Jan 1984 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B41M005-18. APPLICATION: JP 82-111071 28 Jun 1982. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) A recording material has an intermediate layer of a water-sol.In this article, certain chemicals are used. Some of their cas registry numbers are 7333-86-0 and 59129-79-2 resin between each of the heat-sensitive layers and the heat-sensitive layers contain leuco dyes and color developers and are supported by a base film coated with a polymer resin contg. an org. or inorg. filler. The compn. largely eliminates color mixing, spreading, bad head-matching, and other faults of conventional materials. Thus, a mixt. contg. 2-[N-(3-trifluoromethylphenyl)amino]-6-diethylaminofluoran (for black color), hydroxyethyl cellulose, p-benzoic acid benzyl ester (I) (sic), and oxidized starch was coated on a paper support precoated with butadiene-styrene and methacrylic acid-styrene copolymers. An intermediate layer of Me cellulose was formed on this layer, and another mixt. contg. 2-(N-phenyl)amino-3-methyl-6-[N-(p-tolyl)-N-ethyl]aminofluoran (for red color), I, and hydroxyethyl cellulose was further coated to obtain a material, which showed good sepn. of red and black colors without mixing in a test using a 2-color thermal recorder. .

Thermal recording materials

Thermal recording materials. Taniguchi, Keiji (Ricoh Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 61074886 A2 17 Apr 1986 Showa, 7 pp. (Japan) CODEN: JKXXAF. CLASS: ICM: B41M005-18. APPLICATION: JP 84-195930 19 Sep 1984. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Thermal recording materials utilize coloring reactions between 31 fluoran compd. of the formula I or II ((R, R1 = C1-6 alkyl; R2, R3 = C1-2 alkyl, halo; k, n = 0-2; m = 0, 1; R4, R5 = C1-6 alkyl; R6 = C1-2 alkyl, halo; x = 0-2), and a Zn thiocyanate imidazole complex (III; R7 = C1-6 satd.Some commonly used reagents like 68506-98-9 and 59129-79-2 are used in this experiment. or unsatd. hydrocarbon group). High stability of the images against oils, plasticizers, and alcs. is obtained. Thus, the Zn thiocyanate complex of 1-vinylimidazole (IV) was pptd. from the components in EtOH and recrystd. A coating compn. was prepd. by mixing 3 dispersions A, B, and C and a 20% alk. soln. of isobutylene-maleic anhydride copolymer in a 1:3:3:1 ratio. The dispersions contained: (A) 3'-(N-ethyl-N-p-methylphenylamino)-6'-methyl-7'-phenylaminofluoran 20, 10% aq. hydroxyethyl cellulose 20, and H2O 60 parts, (B) IV 20, 5% Me cellulose 20, and H2O 60 parts, and (C) finely pulverized urea-HCHO resin 20, 5% Me cellulose 20, and H2O 60 parts. The compn. was coated on a paper support to form a 4-5 g/m2 layer. The material was used for thermal recording and tested by application of cottonseed oil, contact with a PVC sheet with pressure for 24 h, and application of EtOH. The image d. and the background d. were unaffected in the tests. .
