Zusammenfassung:	A water soluble phenolic resole-urea composition useful as a binder which remains infinitely water-dilutable and free of sediment after one month of storage at 0 DEG C and is made by the reaction of urea with the free formaldehyde in a phenolic resole under acid conditions, followed by the further addition of urea at neutral or slightly basic conditions.
