Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a rapidly and physically drying binder having storage stability and good stone impact resistance. SOLUTION: A preparation method for a coating support is to form a film by applying an aqueous dispersion capable of forming a photostable elastic film when physically cured on a support followed by physically curing the dispersion. The aqueous dispersion comprises: (A) a polyol component containing (AI) 20-60 wt.%, based on resin solid content of the polyol component A, of a polyester resin including 10-60 wt.%, based on weight of the polyester resin, of at least one 8-30C aliphatic saturated or unsaturated monocarboxylic acid and 0.4-5 wt.%, based on weight of the polyester resin, of at least one 3-8C radically polymerizable α,β-unsaturated mono- or di-carboxylic acids or its anhydride, and (AII) 40-80 wt.%, based on resin solid content of the polyol A, of a polyacrylate which is prepared in the presence of the component AI; and (B) containing 1-70 wt.%, based on resin solid content of the aqueous dispersion of at least one blocked polyisocyanate.
