    Coumarin of the formula: ##SPC1## In which R.sub.1 represents an alkyl group having 1 to 5 carbon atoms, and either unsubstituted or substituted by a non-ionic and non-chromophoric group, R.sub.2 represents a benzene, styryl or heterocyclic residue such residue being unsubstituted or substituted by one or two non-ionic and non-chromophoric groups; process for the preparation of a coumarin of the above formula which comprises reacting an orthohydroxy-benzaldehyde of formula (II) upon an acid of formula (III) or one of its functional derivatives: ##SPC2## Wherein R.sub.1 and R.sub.2 have the same definitions as in claim 1; process for the fluorescent brightening of fibrous material of synthetic origin which comprises treating the material with a coumarin of the above formula; fluorescent brightening composition containing a coumarin of the above formula and a dispersing agent resulting from the condensation of naphthalene-sulphonic acids with formaldehyde in the presence of or absence of phenol compounds, said dispersing agent comprising 30% to 50% monosulphonated condensates, 30% to 50% disulphonated condensates and 10% to 40% trisulphonated or higher polysulphonated condensates; fibres of synthetic origin treated with a coumarin of the above formula or with a brightening composition as set out above.
    公式为:##SPC1## 其中R.sub.1表示1至5个碳原子的烷基,可以是未取代的或被非离子和非色团基团取代的;R.sub.2表示苯基,亚基或杂环残基,该残基可以是未取代的或被一或两个非离子和非色团基团取代的;制备上述公式的香豆素的过程包括将公式(II)的邻羟基苯甲醛与公式(III)或其官能衍生物之一发生反应:##SPC2## 其中R.sub.1和R.sub.2的定义与权利要求1中相同;用上述公式的香豆素处理合成纤维材料的荧光增白过程;荧光增白组合物包括上述公式的香豆素和萘磺酸与甲醛在酚类化合物的存在或不存在下缩聚而成的分散剂,所述分散剂包括30%至50%的单磺酸缩聚物,30%至50%的双磺酸缩聚物和10%至40%的三磺酸或更高磺酸缩聚物;用上述公式的香豆素或上述增白组合物处理的合成纤维。

    公开(公告)日:1976-01-20
    Substituted coumarins are described having at the 7-position the group RO- where R is a substituted or unsubstituted alkyl, cycloalkyl or aralkyl group, and at the 3-position a 1,2,4- or 1,3,4-oxadiazolyl group which possesses a substituted or unsubstituted alkyl or aryl substituent. The compounds are useful as optical whitening agents in the treatment of textile fibres.
    描述了替代香豆素,在7-位具有RO-基团,其中R是取代或未取代的烷基、环烷基或芳基基团,并且在3-位具有1,2,4-或1,3,4-噁二唑基团,该基团带有取代或未取代的烷基或芳基取代物。这些化合物在处理纺织纤维时作为光学增白剂是有用的。
