(a) Sulfit und/oder Hydroxymethansulfinat in einer Konzentration von 0,2 bis 3 Gew.%, berechnet als SO₃²⁻ oder Sulfinsäurerest, und (b) Dimethylolharnstoff und/oder Trimethylolharnstoff in einer Konzentration von 0 bis 5 Gew.%, jeweils bezogen auf das Gesamtgewicht der Harzlösung, enthält. An alkaline condensed urea-phenol-formaldehyde resin solution with a dry content of 38 to 60% by weight is proposed, which has an improved storage stability. This resin solution is characterized in that it (a) sulfite and / or hydroxymethanesulfinate in a concentration of 0.2 to 3 wt.%, calculated as SO₃²⁻ or sulfinic acid residue, and (b) dimethylol urea and / or trimethylol urea in a concentration of 0 to 5% by weight, each based on the total weight of the resin solution. |
