摘要:
A floor covering includes a wear layer including a resin and a photoinitiator in which the composition of the wear layer is curable by radiation having the strongest wavelength in the UVV range of 400 to 450 nm. The gloss of the wear layer can be controlled by controlling the amount of flatting agent in the composition applied to the surface, the amount of power applied to the surface coated with the composition or the temperature of the surface coated with the composition when the coated surface is subjected to the UVV radiation.
