    Abstract: The invention relates to a method for the preparation ofcoloured melamine-formaldehyde condensation products. By it,pigments or dyestuffs are mixed in the reaction mixture, and inthe first stage the dispersed mixture contains: a) substitutedmelamine with formulawhere all X1, X2 and X3 are selected from -NH2, -NHR1 and -NR1R2,and not all X1, X2 and X3 are -NH2 and every X1 and X2 is selectedfrom hydroxy-C2-C10-alkyl, hydoxy-C2-C4-alkyl-(oxa-C2-C4-alkyl)n,n being from 1 to 5, and amino-C2-C12-alkyl, or mixtures ofmelamines with formula Ib) optionally fromaldehyde or donor compounds of formaldehyde atmolar ratio of formaldehyde to melamines I from 40:1 to 0, c)pigment or dyestuff, and d) optionally phenol, unsubstituted orsubstituted by radicals selected from the group consisting ofC1-C9 alkyl and hydroxyl, C1-C4 alkanes substituted by 2 or 3phenol groups, di (hydroxyphenyl) sulphones or instead this -mixtures thereof. The pigment or the dyestuff is from 0.01 to 30wt.% and they are based on a) and b), and phenol is from 0 to 5mol % and is based on a) and b), and during the intensiveagitation all pigment aglomerates 21 m disappear. In the secondstage the product of the first stage is mixed with melamine andoptionally with phenol, substituted melamine with formula I, andphormaldehyde or compounds, donors or formaldehyde. Theirquantities are selected in such way that the molar ratio ofmelamines (melamines and a) to b) is from 1:1.15 to 1:4.5, thepigment or dyestuff are from 0.01 to 5 wt.%, based on melamine anda) and b), and phenol is from 0 to 5 mol.% based on melamine anda) and b). Finally, condensation based on the conventional methodis carried out.

    Abstract: Dyed melamine-formaldehyde condensation products are prepared by mixing pigments or dyes with a reaction mixture that contains base compounds for preparing melamine-formaldehyde condensation products. For that purpose (A) a mixture is used that substantially consists of (a) a substituted melamine having the formula (I), in which X1, X2 and X3 are selected from the group that consists of -NH2, -NHR1 and NR1R2, and X1, X2 and X3 are not -NH2 simultaneously, and R1 and R2 are selected from the group that consists of hydroxy-C2-C10-alkyl, hydroxy-C2-C4-alkyl-(oxa-C2-C4-alkyl)n, n being equal to 1 to 5, and amino-C2-C12-alkyl, or mixtures of melamines (I); and optionally (b) formaldehyde or formaldehyde releasing compounds, the molar ratio between formaldehyde and the melamines (I) being selected in a range from 40:1 to 0; (c) a pigment or a dye; and optionally (d) an unsubstituted phenol or phenols substituted with residues selected from the group that consists of C1-C9-alkyl and hydroxy, substituted phenols, C1-C4-alkanes substituted with two or three phenol groups, di(hidroxyphenyl)sulfones or mixtures of such phenols. The amount of pigment or dye ranges from 0.01 to 30 % by weight in relation to (a) and (b), and the amount of phenol ranges from 0 to 5 mol % in relation to (a) and (b). Said mixture is dispersed under intensive stirring until no more pigment agglomerates equal to or larger than 1 .mu.m are present. The mixture produced in (A) is then (B) mixed with melamine and if desired with more phenol, substituted melamine (I) and formaldehyde or formaldehyde releasing compounds, their respective amounts being selected so that the molar ratio between melamines (melamine and (a)) and (b) ranges from 1:1.15 to 1:4.5, the amount of pigment or dye ranges from 0.01 to 5 % by weight in relation to melamine, (a) and (b), and the amount of phenol ranges from 0 to 5 mol % in relation to melamine, (a) and (b). The mixture is then condensed in a known manner.
