| abstract |
PCT No. PCT/JP89/00944 Sec. 371 Date May 14, 1990 Sec. 102(e) Date May 14, 1990 PCT Filed Sep. 14, 1989 PCT Pub. No. WO90/02735 PCT Pub. Date Mar. 22, 1990.The present invention provides an indolenine derivative represented by the formula <IMAGE> wherein R1 is a hydrogen atom or a lower alkyl group, X and Y are the same or different and each represent a methylene group or an oxygen atom. This indolenine derivative is useful as an intermediate for synthesizing a cyanine compound suitable for use as an organic near infrared light-absorbing dye useful as an optical disc recording medium adapted for semiconductor laser recording. |
