Abstract: The use of a 2-(C.sub.3-5 -alkyl)-BIT or 2-aralkyl-BIT such as 2-phenylethyl-BIT as a fungicide for plastics materials. 2-n-Butyl-BIT is preferred.

Abstract: A method for the protection of a medium by susceptible to microbial attack by the treatment of the medium with an oxaborale or a salt of an oxaborale.

Abstract: A dyestuff of the formula ##SPC1##Wherein m is 1, 2 or 3; R.sup.9 is ##SPC2##Wherein n is 0 or 1 and R" is hydrogen or lower alkyl or ##SPC3##Wherein p is 1, 2 or 3; R.sup.10 is C.sub.1.sub.-6 alkyl, benzyl, sulphobenzyl, phenyethyl, sulphophenylethyl, ##EQU1## wherein r is 2 to 6, ##SPC4##Or ##SPC5##Wherein R" has the meaning given above and the dyestuff as a whole contains only one group represented by Z, and Z is a cellulose-reactive group. The dyestuff is useful in dyeing and printing cellulose, polyamide and wool textile materials. Textile dyes with the above dyestuff exhibits good fastness to washing and to bleaching and good resistance to acids and alkalies.
