Kokai Tokkyo Koho JP 61254543 A2 12 Nov 1986 Showa, 8 pp. (Japan) CODEN: JKXXAF. CLASS: ICM: C07C093-14. ICS: C07C089-00. APPLICATION: JP 85-93891 2 May 1985. DOCUMENT TYPE: Patent CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Section cross-reference(s): 35 The title compd. (I), useful as raw material for polyimides, was prepd. 10527-11-4 and 100-00-5 which are cas registry numbers are also used here. Thus, treating 1-(4-hydroxyphenyl)-1,3,3-trimethyl-6-hydroxyindan with 4-chloronitrobenzene in Me2SO in the presence of aq. NaOH at 100-110° gave 99.3% 1-[4-(4-nitrophenoxy)phenyl]-1,3,3-trimethyl-6-(4-nitrophenoxy)indan, which was reduced in EtOH over Pd(5%)/C at 62-68° to give 87.6% I. Polyimides from I and 3,3',4,4'-benzophenonetetracarboxylic acid dianhydride showed a glass transition temp. of 260°, and a temp. for 5% wt. loss in air of 508°. .

Thermal printing material containing sulfonylaminophenol and hydroxyindan as color developers

Thermal printing material containing sulfonylaminophenol and hydroxyindan as color developers. Ono, Osamu (Oji Paper Co., Ltd. 10527-11-4 and 1146-43-6 are also occured in this study., Japan). Jpn. Kokai Tokkyo Koho JP 2003025739 A2 29 Jan 2003, 7 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: ICM: B41M005-30. ICS: B41M005-26. APPLICATION: JP 2001-220840 23 Jul 2001. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) The material comprises a support coated with a heat-sensitive layer contg. a leuco dye, N-(p-toluenesulfonyl)-p-aminophenol and 1,3,3-trimethyl-1-(p-hydroxyphenyl)-6-hydroxyindan as color developers, a sensitizer, and a binder. The material shows good storage stability, running property, high sensitivity, and gives images without background fog. .
