    摘要: Aqueous binder dispersions, which may be produced by 1) mixing 50 to 95 solids pbw (parts by weight) of non-aqueous polyurethane resin with 5 to 50 solids pbw of non-aqueous aminoplast resin, wherein the total of the solids pbw amounts to 100 and wherein polyurethane resin and aminoplast resin are inert towards each other, 2) converting the resultant non-aqueous mixture into an aqueous dispersion by mixing with water, and 3) subjecting the resultant aqueous dispersion to conditions which give rise to condensation reactions of the aminoplast resin present in the dispersion particles, until a tetrahydrofuran-insoluble binder fraction of the dispersion solids of 20 to 90 wt. % is obtained.
