Zusammenfassung:1. Isocyanate-reactive mixtures of a) 20 to 90%, by weight (based on a) + b)) of a mixture of polyhydric alcohols, hydroxy aldehydes and hydroxy ketones which has been obtained by the condensation of formaldehyde hydrate from an aqueous formalin solution and/or paraformaldehyde dispersion, b) 10 to 80% by weight (based on a) + b)) of aldehydes and/or ketones methylolated in the alpha-position and incapable of endiol formation, and c) 0 to 50% by weight (based on a) + b)) of water.
