Abstract
The invention provides a sheet coated with a powdery coating composition comprising a substrate and a porous and continuous resin layer provided on the substrate, the resin layer comprising particles of the powdery coating composition having an average particle diameter of 0.1 to 30 &mgr;m and inorganic fine particles having an average particle diameter of 1 nm to 1 &mgr;m and dispersed between the particles of powdery coating composition to form space at least in part therebetween. The sheet is suitably used as an image-receiving sheet for an ink-jet recording.The sheet can be obtained according to the invention by mixing a powdery coating composition having an average particle diameter of 0.1 to 30 &mgr;m with inorganic fine particles having an average particle diameter of 1 nm to 1 &mgr;m to form a powdery mixture, dry-coating the powdery mixture on a substrate, melting the powdery coating composition by heating, and fixing the coating composition together with the inorganic fine particles on the substrate to form a resin layer comprised of the powdery coating composition.
