Zusammenfassung:1-(4'-beta-acylaminoethylsulphonyl)phenyl)-3-aryl-DELTA2-pyrazoli- nes where R = opt. subst. aryl (esp. phenyl or p-chlorophenyl), Y = -CO- or -SO2-, R' = H, C is not >20 alkyl, opt. subst. aryl or aralkyl grp. and R2 = low alkyl, cycloalkyl, opt. subst. aryl or styryl. Products are colourless or pale yellow materials useful as UV absorbers for paper, optical brighteners for fibres and textiles, e.g. of cotton, polyacrylonitrile, cellulose 2 1/2- and 3-acetate, etc., with good resistance to hypochlorite treatment. They may also be used as additives to spinning masses and to plastics materials such as polyvinyl chloride, polyethylene, polypropylene etc., fibres, films etc.
