Disclosed is a method for producing alkoxycarbonylamino triazines of formula (I) by reacting diaminotriazines or triaminotriazines with cyclic carbonic acid esters and optional subordinate quantities of acyclic carbonic acid esters in the presence of an alcohol and an alkaline alkanol or alkaline-earth alkanol as a base. In said formula, Y1 represents hydrogen, C1-C4 alkyl, phenyl that is optionally substituted by C1-C4 alkyl, C1-C4 alkoxy, or halogen, or a radical of formula NR5R6 while R1, R2, R3, R4, R5, and R6 independently represent hydrogen or a radical of formula COOX or X, wherein X represents C1-C13 alkyl, the carbon skeleton of which can be interrupted by 1 or 2 oxygen atoms having the function of ether and/or substituted by hydroxy, or C3-C6 alkenyl provided that at least one of the radicals R1 to R4 in formula (I) represents COOX, or at least one of the radicals R1 to R6 in said formula represents COOX if Y1 represents NR5R6.
