Beschreibung
Zusammenfassung:	The present invention relates to heat-reactive crosslinking agents for paint resin binders based on phenolic Mannich bases, obtainable by reacting A) one equivalent of a polyphenol with B) 0.5 to 2 equivalents of formaldehyde or a formaldehyde-supplying compound and C) 0.5 to 1 equivalent of at least one secondary aliphatic amine, removing the water of reaction and reacting the resultant reaction product with D) 0.01 to 1 equivalent of a mono- and/or polyfunctional isocyanate compound.
