Procedure

the melamine-formaldehyde precondensate used as starting material is miscible with water in every ratio without cloudiness. These precondensates are obtained by condensation of melamine with formaldehyde in the molar ratio from 1:3 to 1:6 and subsequent partial etherification with C1 -C4 -alkanols, preferably methanol, and
