    摘要: Disclosed are basic dyes, e.g., azo dyes and anthraquinone dyes free from sulphonic acid groups and which contain, as characteristic group, a group of the formula ##STR1## in which R and R.sub.1, independently, are substituted or unsubstituted C.sub.1-4 alkyl or are linked to form a ring, orOne of R and R.sub.1 is --NH.sub.2 or C.sub.1-4 alkoxy, the other substituted or unsubstituted alkyl,R.sub.2 and R.sub.3, independently, are hydrogen or C.sub.1-4 alkyl,Y is a bridging group,Q is unsubstituted or substituted phenyl, biphenylyl, naphthyl or ##STR2## in which R.sub.7 is ##STR3## where R.sub.8 ic C.sub.1-4 alkyl, andA.sup.- is an anion. These dyes are useful for the dyeing and printing of polymers and copolymers of acrylonitrile and asymmetrical dicyanoethylene as well as polyesters and polyamides modified to contain acid groups. The dyes build-up well and exhibit good pH stability and stability to boiling. The obtained dyeings are level and possess good fastness to light, wet treatments, solvents, heat treatments and cross-dyeing.

    摘要: The production of aminonitrodihydroxyanthraquinones of the formula: ##STR1## in which one X is OH and the other X is NO.sub.2 by partial reduction of the corresponding dinitrodihydroxyanthraquinone or mixtures thereof by heating at 80.degree.-250.degree. C in the presence of 1/2 to 5 times the weight thereof of an unsubstituted or substituted phenol. The reduction is accelerated by being carried out in the presence of a small amount such as 0.5-20 mol percent of an alkaline-reacting agent. Pure aminonitrohydroxyanthraquinones are obtained which are free from diaminodihydroxyanthraquinones.

    摘要: A thermal transfer sheet that yields three-color black printed matter having an extremely high density, and a method for producing printed matter using the thermal transfer sheet are provided. The thermal transfer sheet includes a substrate film and a dye layer containing a magenta dye disposed on one surface of the substrate film, and the magenta dye includes at least one of an anthraquinone-based dye represented by general formula (1) below and an anthraquinone-based dye represented by general formula (2) below. An image is formed by a thermal transfer method using the thermal transfer sheet. (In general formula (1), R1 is a phenyl group which may have a substituent. In general formula (2), R2 is a hydrogen atom or an alkyl group having 1 to 4 carbon atoms. Ra and Rb are each independently a hydrogen atom or a nitro group.)
