A process for the manufacture of N-(2,4-dihalo-s-triazin-6-yl)-ureas of the formula ##SPC1## Wherein X represents halogen, R represents alkyl, aryl or hydrogen and Y represents hydrogen or the sulphonic acid group, which comprises reacting a dihalo-amino-s-triazine of the formula ##SPC2## Wherein X and R have the meanings assigned to them hereinbefore, with chloro-sulphonylisocyanate and hydrolysing the resulting reaction product. The compounds of the formula (1) are suitable as starting products for the manufacture of reactive dyes, fluorescent whiteners or agro - chemicals.
