Condensation products obtainable by the condensation of a mixture containing as the essential components: (A) 90 to 99.9 mol% of a mixture substantially consisting of (a) 30 to 100 mol% melamine and (b) 0 to 70 mol% of a substituted melamine of general formula (I) in which X, X' and X'' are selected from the group consisting of -NH2, -NHR and -NRR', and X, X' and X'' are not -NH2- simultaneously, and R and R' are selected from the group consisting of hydroxy-C2-C10-alkyl, hydroxy-C2-C4-alkyl-(oxa-C2-C4-alkyl)n, where n = 1 to 5, and amino-C2-C12-alkyl, or mixtures of melamines of general formula (I), and (c) 1 to 70 mol%, related to (a)+(b), of a substituted triazine of general formula (II) in which R'' is methyl or phenyl and Z' and Z'' are selected from the group consisting of -NH2, -NHRIII and NRIIIRIV, and RIII and RIV are selected from the group consisting of hydroxy-C2-C10-alkyl, hydroxy-C2-C4-alkyl-CH2CH2-S-CH2CH2OH and amino-C2-C12-alkyl, or mixtures of the triazines of general formula (II), and (B) 0.1 to 10 mol%, related to (A) (a), (A) (b) and (B), of unsubstituted phenols or phenols substituted by radicals selected from the group C1-C9-alkyl and hydroxy, C1-C4-alkanes substituted with two or three phenol groups, di(hydroxy phenyl)sulphones or mixtures of these phenols, with formaldehyde or formaldehyde-yielding compounds, in which the molar ratio of melamine, substituted melamine of general formula (I) and triazine of general formula (II) to formaldehyde is in the range from 1:1.15 to 1:4.5, and a process for their production, their use in the manufacture of mouldings and such mouldings.
