A material or container covered with a hardened coating film is obtained by coating the surface of a substrate made of a resin or the like with a hardenable coating resin composition comprising (a) a poly[(meth)acryloyloxyalkyl](iso)cyanurate of general formula (1) or (2) (wherein X , X and X are each (meth)acryloyl, hydrogen or alkyl (at least two of them being (meth)acryloyl); and R , R and R are each oxyalkylene or polyoxyalkylene), (b) a polyoxyalkanepolyol poly(meth)acrylate, (c) 2-methyl-[4-(methyltio)phenyl]-2-morpholino-1-propanone as photopolymerization initiator, (d) a thioxanthone photopolymerization initiator, (e) a monohydroxybenzophenone ultraviolet absorber, and (f) an organic solvent. The material and container thus coated are superior to those of the prior art in hardening characteristics and characteristics of hardened coating film, being suitable for utilization as a re-usable coated material. Matériau ou récipient recouvert d'un film de revêtement durci, que l'on obtient en recouvrant la surface d'un substrat en résine ou analogue d'une composition de résine de revêtement durcissable comportant (a) un poly[(méth)acryloyloxyalkyle](iso)cyanurate de formule générale (I) ou (II) dans lesquelles X , X et X sont chacun (méth)acryloyle, hydrogène ou alkyle (au moins deux d'entre eux étant (méth)acryloyle), et R , R et R sont chacun oxyalkylène ou polyoxyalkylène), (b) un poly(méth)acrylate de polyoxyalcanepolyol, (c) 2-méthyle-4-(méthyltio)phényle]-2-morpholino-1-propanone en tant qu'initiateur de photopolymérisation, (d) un initiateur de photopolymérisation thioxanthone, (e) un absorbeur d'ultraviolets monohydroxybenzophénone et (f) un solvant organique. Le matériau et le récipient dotés dudit revêtement sont supérieurs à ceux de la technique antérieure pour ce qui est des caractéristiques de polymérisation et de celles présentées par le film de revêtement durci, constituant ainsi un matériau ou récipient à revêtement réutilisables.
