難かった。Further, in the case of a manufacturing method using an ultraviolet-curable unsaturated polyester resin liquid obtained by adding a reaction diluent or a photopolymerization initiator to an unsaturated polyester resin, the resin liquid is applied onto a substrate and then directly irradiated with ultraviolet rays. Although it was passed through the device and cured, the manufacturing time is shortened compared to the ordinary polyester decorative board, but dust etc. adhere to the resin liquid during curing and the air in the decorative paper is in the resin liquid. It was difficult to obtain a beautiful decorative board because the surface was uneven and formed due to foaming.
