Abstract
Method of coating a substrate comprising the steps of: i) applying to the substrate a radiation curable aqueous composition comprising a dispersed polymeric binder, ii) thermally drying the aqueous coating composition and iii) electron beam curing the coating composition, the method being characterized by the fact that the aqueous coating composition is a physically drying, film-forming aqueous composition and that the curing is performed in air atmosphere.

Method of coating a substrate comprising the steps of:
- applying to the substrate from 0.1 to 250 g/m2m2 (dry matter) of a radiation curable aqueous composition comprising from 15 to 50 wt % of a dispersed polymeric binder and from 0 to 15 wt % of an unsaturated reactive diluent;
- thermally drying the aqueous composition to form a dust-free film;
- and
- electron beam curing the thermally dried composition,
- the method being characterized by the fact that the dispersed polymeric binder is a polyurethane binder, the aqueous coating composition is a physically drying, film-forming aqueous composition containing from 100 to 600 meq/100 g (dry matter) of radiation curable unsaturated groups and that the curing is performed in air atmosphere.
