Abstract

PURPOSE: To continuously produce a precise high light diffusion plate, by laminating an acrylic film F, acrylic resin plate L, and high diffusion plate P to one body using a nonhardened monomer of resin L, its prepolymer, or an acrylic binder for layer P.
CONSTITUTION: For example, a light diffusing agent, such as SiO2 is dispersed into an acrylic binder, and this coating fluid is fed from tank 171 of coating apparatus 17 to belt 1 in a space surrounded by endless belts 1, 1' each running in the same direction, and gaskets 7, 7', and then, acrylic film F is fed from feeder 15. Next, the start material monomer of synthetic resin plate L of a copolymer made of 90wt% or more methyl methacrylate, or its prepolymer is injected from injection opening 6 with pump 5, it is held with roller groups 4, 4', heated with not water sprays 8, 8' in heater 19, and further heated with far infrared heaters 9, 9' in heater 19 to make polymerization, and taken out through coolers 10, 11. Thus, film F is partially dissolved or swelled by the monomers or prepolymers of plate L and layer P, and subsequently hardened by polymerization, resulting in perfectly forming into one body with L and P.
