    摘要： PROBLEM TO BE SOLVED: To provide an indicator for measuring dissolved oxygen concentration with high thermal stability and reasonable reactivity between a coloring matter and a reducing agent, not too strong nor too weak, which detects the presence of dissolved oxygen according to color density based on the color at the time when the concentration of dissolved oxygen is 0, which dissolves even after reduction of coloring matter, and which permits confirmation of differences in color development by a spectrophotometer within the range of 0.05 ppm through 5.0 ppm of dissolved oxygen concentration after such materials affecting color development are removed. SOLUTION: This indicator for measuring dissolved oxygen concentration comprises coloring matters as methylene blue or indigo carmine; a reducing agent containing sulfur with valency of III or IV, a reducing agent containing at least one of a stannic chloride and a borohydride; a residual chlorine dissolving agent; a masking agent; and a solvent.

    摘要： PROBLEM TO BE SOLVED: To form a good minute recording part having almost no rim and to reduce bit length jitter, in an optical recording medium in which an org. dye layer is provided on a substrate suitable for reproducing recording by laser beam having a specific wavelength, by adding a specific indigo compd. to the org. dye layer. SOLUTION: It is necessary that an org. dye layer has spectral absorption max. within a wavelength range of 510-730nm. When there is absorption max. within a short wavelength region of 510nm or less, sufficient sensitivity is not obtained in layered constitution or a good reproduction signal is not obtained. Even in the org. dye layer having absorption max. on the side of a long wavelength of 730nm or more, the same result is brought about. Then, an org. dye containing an indigo compd. represented by formula [wherein X and Y are a sulfur atom, a selenium atom or NR (wherein R1 is a hydrogen atom or an alkyl group) and n is 0, 1 or 2] is used in the org. dye layer.

    摘要： PURPOSE: To dye keratin fiber with excellent light resistance and weather resistance by using a combination of an isatin or its derivative with a tri--penta- substituted aniline dye or a bis-(phenylalkylene)diamine type compound. CONSTITUTION: Human hair is dyed by using a compound of formula I (R1 is H, an alkyl, phenyl; R2 and R3 are H, an alkyl, an alkoxy) (typically isatin is suitable), a di-, tri- or tetra-substituted aromatic diamine or aminophenol of formula II (Y is OH, R4 to R7 are each H, an alkyl where at most two of them are H) or their salt except 2,5-dimethoxy-1,4-diaminobenzene (typically 2-methoxy-3,5-dimethyl-1,4-diaminobenzene or a bis-phenylalkylenediamine of formula III [R12 is OH, amine, H, an alkyl; Z is (CH2 )n (n is 0-8)] or its acid adduct [typically N,N'-bis-(β-hydroxyethyl)] in a medium.

    摘要： PURPOSE:To produce an indigo in a very high yield in one stage by a simple process, by reacting an indole having no substituents in the positions 2 and 3 with a peroxycarboxylic acid in the presence of a specified solvent. CONSTITUTION:An indigo is produced by reacting an indole having no substituents in the positions 2 and 3 (e.g., indole) with a peroxycarboxylic acid (e.g., m-chloroperbenzoic acid) in the presence of an alcohol solvent (e.g., methanol). Although a conventional process for producing indigo comprises producing an N-phenylglycine salt from either aniline and chloroacetic acid, of aniline, cyanic acid and formaldehyde and converting this salt into an indoxyl compound by alkali fusion at high temperatures and oxidizing it with air, this process is complicated and requires a large quanty of energy. According to the process of this invention, it is possible to produce an indigo in a very high yield in one stage by a very simple process.
