The invention relates to a method for producing a formaldehyde-free amino resin or amide resin, comprising (i) the reaction of an amine or amide with a monoaldehyde that has at least 2 C atoms to form an intermediate product that has a reactive protective group on at least one amine group or amide group, said protective group being derived from the monoaldehyde, and (ii) the reaction of the intermediate product with a dialdehyde or trialdehyde to form a crosslinkable amino resin or amide resin. The invention further relates to an amino or amide resin obtainable using said method.
