Abstract

Aqueous aminoplast resins with a solids content of 50 to 75 wt % and a viscosity, related to a solids content of 67 wt %, of 150 to 400 mPa.s (measured at 20 DEG C and a shear gradient of 500 s<-1>) containing per mol melamine (component a) 0.5 to 13 mol urea (component b), 2 to 20 mol formaldehyde (component c), 0 to 1 mol phenol and/or a condensable phenol derivative (component d), 0 to 1 mol of an alkaline sulphite and/or alkaline hydrogen sulphite (component e) and 0 to 1 mol of a further condensable compound (component f), in which the ratio of the sum of the mol quantities of the (-NH2) groups originally present in components (a) and (c) to that of component (c) is 0.5:1 to 2:1.
