The invention relates to biuret compounds of the idealized general formula Image in which R1 is a(C1-C22) -alkylene, (C3-C22) -alkenylene, (C5-C15) -cycloalkylene, arylene, (C7-C-12) -aralkylene, a polyoxyalkylene radical or is a polyester radical, R2 is a (C1-C222) -alkyl, hydroxy- (C1-C22) -alkyl, (C3-C18) - alkenyl, aryl, (C7-C12) -aralkyl, or (C5-C12) -cycloalkyl radical, a hydroxy-, (C1-C22) -alkoxy-, (C5-C12) -cyclo- alkoxy-, or (C7-C12)-aralkoxy-polyoxyalkylene radical, or a polyester radical prepared starting from a (C1-C22) -alkanol, (C5-C12) -cycloalkanol, or (C7-C12) - aralkanol or from a (C1-C22) -alkoxy-, (C6-C12) -cyclo- alkoxy-, or (C7-C12)-aralkoxy-polyoxyalkylene, Y stands for identical or different radicals O, NH, CO-NH-NH or NH-NH-CO, R3, R4 and R5 independently of one another are a (C2-C40) -alkylene, (C3-C40) -alkenylene, (C5-C40) -cyclo- alkylene, arylene, (C7-C40) -aralkylene or polyoxy- alkylene radical or are a polyester radical, R6 is a (C1-C30) -alkyl, (C3-C-22) -alkenyl, hydroxyalkyl and hydroxyalkenyl, (C4-C13) -cycloalkyl, aryl or (C7-C12) - aralkyl radical, Z stands for one or more of the following groups COO, OCO, NHCO, CONH, NHCOO, OOCNH and NHCONH, and a is a number from 1 to 19, and also to processes for preparing them and to their use for rheology control and for thixotroping coating systems, as anti-sag agents and/or as anti-settling agents.
