    Abstract: PURPOSE:To provide the subject derivative comprising a 2-alkoxy-3,5- diaminopyridine derivative, and useful as a coupling agent for corneal fiber- dyeing agents which can dye hair, etc., into a blue color tone having a high chroma and which have good dyeability, discoloration resistance and water resistance. CONSTITUTION:A 2-halogeno-3,5-dinitropyridine of formula I (X is halogen) (e.g. 2-chloro-3,5-dinitropyridine) is reacted with a metal alkoxide of formula MOR (R is lower alkyl which may have a hydroxyl group; M is alkali metal) (e.g. sodium methoxide) in methanol at room temperature, and the produced 2-alkoxy-3,5-dinitropyridine is reduced into a diamine derivative of formula II. The diamine derivative of formula II is mixed with acetic anhydride, etc., and a NaOH aqueous solution to give a pH of 6-7, and reacted with each other. The reaction product is diluten with water, extracted with a solvent and subsequently purified with a silica gel chromatography to obtain the 2-alkoxy-3,5- diaminopyridine derivative of formula III (R , R are H, lower alkanoyl, etc.).

    Abstract: PURPOSE:To provide a novel aminophenol derivative or a salt thereof having good dyeability, discoloration resistance, washing resistance and abrasion resistance and useful as a coupling substance for obtaining a color tone having a high chroma. CONSTITUTION:An aminophenol derivative of formula 1 (R is lower alkyl; (n) is 2-4), e.g. 2-amino-4-hydroxy-5-methylphenoxyethanol. A nitrophenyl derivative of formula 2 (R is H, alkylsulfonyl, arylsulfonyl) or a salt thereof as an intermediate, e.g. 5'-nitro-4'-(beta-hydroxyethoxy)-2'-methylphenylmethane sulfonate. The compound of formula I is obtained as follows; reacting a compound of formula III with ethylene oxide or an omegahaloalcohol to form a compound of formula II (R is the groups excluding H), hydrolyzing the formed compound of formula II to form the compound of formula II (R is H), and subsequently reducing the formed compound of formula II.

    Abstract: A dye composition for keratinous fibers which contains a coupler and a developer are disclosed. The present coupler component is a novel 2-alkoxy-3,5-diaminopyridine derivative of the formula (1): wherein R1 and R2 are the same or different from each other and independently represent a hydrogen atom, a lower alkanoyl group or a lower alkyl group which may be substituted by at least one hydroxyl group, and R3 is a lower alkyl group which may be substituted by at least one hydroxyl group, or a salt thereof; provided that R1 and R2 are not both a hydrogen atom or an acetyl group at the same time. The present 2-alkoxy-3,5-diaminopyridine derivatives are useful as couplers in dye compositions, and are capable of dyeing keratinous fibers such as hair in a bright blue color with excellent dyeability. Dye compositions containing the present compounds as a coupler show excellent resistance to discoloration, excellent resistance to shampooing and excellent resistance to friction.
