Abstract: Aq. melamine/HCHO resins contg. a guanamine (I) are claimed. Pref. (I) is benzoguanamine or 5-17C alkyl-guanamine, esp. caprino-guanamine (IA). The melamine: (I): HCHO molar ratio is 1: (0.001-0.5):(1.3-6). The resin may be (partly) etherified with 1-4C alcohols, esp. using a melamine:alcohol molar ratio of 1:(0.8-6). The resin contains 60-85 wt.% solids. The resin is prepd. by reacting melamine and (I) with HCHO; opt. etherification with a 1-4C alcohol; and adjusting the prod. to the required solids content. (claimed).
