Abstract
A process for the preparation of etherified or non-etherified aminoplast resins, wherein an aminotriazine of the general formula (I) ##STR1## where X is hydrogen, alkyl, phenyl, alkylphenyl or --NH.sub.2, is reacted with a .beta.-hydroxyaldehyde of the general formula (II) ##STR2## where R', R' and R'' are identical or different and each is hydrogen or alkyl, or R' and R'', together with the .alpha.-carbon atom, are a cyclopentane or cyclohexane ring, and R' and/or R'' can be hydroxyalkyl and R' can be phenyl, the reaction being carried out in the presence of not less than one alcohol and an acid catalyst for the preparation of etherified aminoplast resins and in the presence or absence of an acid catalyst for the preparation of non-etherified aminoplast resins. The aminoplast resins prepared according to the invention can be used as surface-coatings raw materials.
