Abstract: Aqueous melamine resin mixture (I) comprises a resin content (50-70 wt.% based on (I)) comprising polyvalent alcohols (a) (1-10 wt.%), caprolactam (b) (0-8 wt.%) and 2-(2-phenoxy-ethoxy)-ethanol (c) (0.5-10 wt.%) and/or polyethylene glycol (d) with an average molecular weight of 200-1500, respectively based on (I); where the molar ratio of melamine and formaldehyde present in the resin is 1:3-1:1. Independent claims are also included for the preparation of (I) comprising converting (I) in a pH of 8-10 at 60-160[deg]C; and a composite material obtained by thermal treatment of (I) with a support material.
