<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method which can recycle an end material produced during production and can produce a laminated resin plate with coloring suppressed enough. <P>SOLUTION: The manufacturing method includes an end material obtaining process in which after a laminated plate is obtained by laminating a surface layer containing a transparent resin (B) on at least one side of a base layer containing a transparent resin (A), at least one part of the peripheral part of the laminated plate is cut to classify it as the end material and a process for producing the laminated resin plate by laminating the surface layer containing the transparent resin (B) on at least one side of the base layer made of a resin composition obtained by mixing the transparent resin (A) with the end material or the end material. When the absolute value of the difference between the SP value of the transparent resin (A) and the SP value of the transparent resin (B) is (Δδ), and the absolute value of the difference between the refractive index of the transparent resin (A) and the refractive index of the transparent resin (B) is (Δn), the relational expression:Δδ×Δn≤0.42 is set up. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
