Abstract

The invention concerns a process for preparing aqueous aminoplastic resins which are suitable as binders for producing derived timber products. The process is characterized in that: a) 1 mole melamine; b) a concentrated aqueous solution of 0.5 to 5 moles urea and 3 to 6 moles formaldehyde per mole of urea, in which urea and formaldehyde can also be present in the form of their reaction products, c) 0.01 to 0.5 moles phenol or a phenol derivative which can be polycondensed, d) 0 to 9 moles formaldehyde, and e) 0 to 1 mole of a further compound which can be polycondensed are reacted with one another at 50 to 100 DEG C and a pH of 7.5 to 10.0 until the solution attains a viscosity of 10 to 1500 mPa.s, after which this solution is left to cool, and f) is mixed with 0.55 to 0.75 moles urea per mole of the total amount of urea used as components (b) and (f).
