Fluorescent polyvinyl alcohol-based resin molded article and a method of manufacturing

PVA molded body containing an average particle size of 50nm less phosphor particles 0.5% by mass or more fluorescing 350~700nm wavelength region under ultraviolet irradiation, and the molded product, (i) under ultraviolet irradiation PVA moldings in immersed in a liquid containing the wavelength range metal compound emitting fluorescence (F) or containing metal ions (a) to form the or a metal ion (a) and the activator ions (C); and then (ii) a metal ion It was immersed in a solution containing ions (B) to form a metal compound (F) which reacts with (a) fluoresces to the wavelength region under irradiation of ultraviolet light, a metal which emits fluorescence on the wavelength range PVA molded body after an average particle size consisting of compound (F) is to produce a less fluorescent fine particles 50 nm, further (iii) the the PVA molded body, the liquid containing metal ions (a) and an ion (B) or a metal ion (a ) and the method of manufacturing and immersed in aging treatment on ion (B) and the activator ions (C), its presence under visible light Not certified, to produce a PVA-based resin molded article containing the fluorescent fine particles of nm size emits strong fluorescence under ultraviolet irradiation.
