    Abstract: 1491343 Naphthacenequinone compounds MITSUI TOATSU CHEMICALS Inc 4 Feb 1975 [7 Feb 1974] 4766/75 Heading C4P Naphthacene quinone derivatives have the formula in which R 1 , R 2 , R 3 and -CO-X-CO- are substituents in the optional positions on the rings of the compound; R 1 and R 3 may be the same or different and represent a hydrogen atom, a chlorine atom, an hydroxyl or an amino group; R 2 represents a radical represented by the formulae: (i) -COOR 4 in which R 4 represents a hydrogen atom, an alkyl, alkoxyalkyl, cyclohexyl or aralkyl group or a cation; in which R 5 and R 6 may be the same or different and represent a hydrogen atom, an alkyl or aryl group; (iii) -CONH-R 7 in which R 7 represents an amino group; in which R 8 and R 9 may be the same or different and represent a hydrogen atom, an alkyl, alkoxyalkyl, or aryl group; (v) in which R 10 represents a methyl group or a chlorine atom, or (vi) -SO 3 -R 11 in which R 11 represents a cation; and X represents a hydrazo or an aromatic diamino group. The compounds may be used as dyes or pigments with synthetic or semisynthetic high molecular weight organic compounds, such as amino-formaldehyde resin, polymers or copolymers of methacrylic acid ester, vinyl chloride, vinylidine chloride, olefines or styrene, polyamides, polyesters, or plyacrylic, polyacetal, phenol, alkyd, epoxy, cellulose acetate, nitrocellulose or cellulose ester resins.

    Abstract: Method of coloring a synthetic or semisynthetic organic high molecular weight material with a asymmetric thioindigoid compound having the formula WHEREIN R1, R2 and R3 may be the same or different and are selected from the group consisting of a hydrogen atom, chlorine atom, lower alkyl group, lower alkoxy group, cyclohexyl group, phenyl group, benzyl group and styryl group, the benzene nucleus of the phenyl and benzyl group may be optionally substituted with a methyl group or chlorine atom, R1 and R2 may together form a tetramethylene ring, R4 is a hydrogen atom or methyl group with the proviso that R4 is a methyl group when R1, R2 and R3 are each a hydrogen atom and R4 is a hydrogen atom when R1 is a methyl group and R2 and R3 are each a hydrogen atom. The colored organic high molecular weight materials exhibit brilliant nuance with characteristic fluorescence.

    Abstract: 1,163,889. Triazole derivatives. MITSUI KAGAKU KOGYO K.K. 28 Nov., 1967 [3 Dec., 1966], No. 54168/67. Heading C2C. [Also in Division D1] The compound where A is an acenaphthene ring or naphthalene ring containing an alkoxy group, R 1 is a cyano, or substituted carbonyl group (R-CO-) where R is hydroxyl, alkoxyl, substituted alkoxyl or substituted amino group; and R 2 is H, methyl or chlorine, is made by coupling the resulting diazonium compound of the compound with the compound to form the compound Ring closure is then carried out by oxidation to form the compound. These compounds are used as optical whitening agents.
