Abstract

Modified aminoplast resins based on melamine and formaldehyde or urea and formaldehyde, which contain, as modifiers, methylolmelamines having a molar ratio of melamine to formaldehyde of 1:3 to 1:6, which are etherified with mono-alcohols having 1 to 4 carbon atoms, in a ratio of melamine to alcohol of 1:2 to 1:6. These resins are used, in particular, for the production of decorative, glossy-surface laminations.
