A transparent layer 1, a light storage pigment-containing layer 2, and a white concealing layer 3 are formed in the shape of a sheet by extrusion or a calender roll, after these sheet layers are finished into a three-layer structure 4 by lamination or pressing or a laminated sheet made of the three-layer structure at a time by a three-layer T die extrusion method. The laminated sheet is pulverized and classified into particles or scale-shaped chips to have the light storage function to be able to deliver as a flooring material or a sheet for a sign, a molding, a housing related member, convenience goods, etc. COPYRIGHT: (C)2008,JPO&INPIT
