<p>A method for the production of decorative, wear-resistant coating film involves impregnating a paper or plastic fibre support with resin, applying a base layer containing radiation-curing resin and abrasive filler to the still-moist support, drying the base layer, applying a topcoat containing resin as above but no filler and then crosslinking both layers by UV and/or electron beam radiation. A method (M1) for the production of sheet- or strip-like, decorative, abrasion-resistant coating material (I), especially coating film, involves (a) impregnating an absorbent supporting layer containing paper and/or plastic fibres with an impregnating resin, (b) applying a liquid or paste-like base layer (12) containing radiation-curing resin(s) and abrasive filler(s) to the still-moist support, (c) drying the base layer (12), preferably by heating, (d) applying a topcoat (14) containing resin as above but no abrasive filler and (d) crosslinking both layers (12) and (14) by UV and/or electron beam (EB) irradiation. Independent claims are included for (1) a method (M2) for the production of coating material (I), especially coating film, by performing stages (a) and (b) as above and then drying the base layer (12), preferably by heating (2) coating material (I) made by M1 with a transition zone (16) between the support (10) and the base layer (12), containing both impregnating resin from the support and crosslinked resin from (12) (3) coating material (Ia) made by M2 , with an uncrosslinked or partly crosslinked base layer and a transition zone (16) as above between the support (10) and the base layer (12) .</p> |
