Abstract

Dyes of the formula <FORM:0584609/IV/1> wherein R1 and R2 are the same or different and are hydrogen atoms or substituted or unsubstituted hydrocarbon groups, R3 is an aromatic nucleus or heterocyclic nucleus, and n is 0 or 1 are prepared by reacting a 5-pyrazolone with an aldehyde of the formula R3-(CH=CH)n-CHO, preferably in the presence of a base. The 5-pyrazolone may be substituted in the 1- and/or 3-position by methyl or higher alkyl, by aralkyl such as benzyl, or by aryl such as phenyl or naphthyl. Such substituent groups may be substituted by further groups such as sulphonic acid groups. The aldehyde may be furfural, furfural acrolein, cinnamaldehyde, or p-dimethylaminobenzaldehyde. In example 1, a dye is prepared by refluxing together 1-phenyl-3-methyl-5-pyrazolone, furfural and aqueous sodium acetate solution. In example 2, a dye is prepared by heating together 1-p-sulphophenyl-3-methyl-5-pyrazolone, cinnamaldehyde and pyridine. In example 3, a dye is prepared by heating together 1-p-sulphophenyl-3-methyl-5-pyrazolone, furfural and pyridine. Specifications 396,646; 540,382, 548,411, [both in Group XX], and 575,512 are referred to.
