ある。2. Description of the Related Art Polycarbonate resin plates are used in a wide variety of applications because they have excellent transparency and impact strength. When coloring, polycarbonate resins and colorants are usually weighed and mixed, and then extruded by an extruder. A method of kneading and then extruding into a sheet is generally adopted. In such a method, the weighing machine, the mixer, and the extruder must be cleaned when the colorant is changed, and in particular, a large amount of uncolored polycarbonate resin is consumed for purging the extruder, which is a great economic disadvantage. Occurs. Further, when the colorant is handled, the colorant scatters indoors, which seriously damages the working environment, and it is necessary to take measures against it. Further, in the case of coloring with a pigment, there is a problem that the impact strength of the polycarbonate resin plate is lowered by the pigment.

になるので、０．５〜１５mm程度の範囲が好ましい。The thickness of the plate made of the polycarbonate resin is not particularly limited, but if it is too thin, the laminate obtained by thermocompression bonding of the film tends to warp, and if it is too thick, the flatness of the laminate obtained. Therefore, the range of about 0.5 to 15 mm is preferable.

m and its total light transmittance must be 50% or less. If the thickness is less than 10 μm, thermocompression bonding operation becomes difficult, and if it is thicker than 200 μm, poor adhesion occurs. Further, when the total light transmittance is higher than 50%, the difference in impact strength becomes small as compared with the method in which the pigment is directly kneaded with the resin, and the advantage of this method becomes poor.

A weatherproofing agent may be added to the colored film together with a coloring agent, and the weatherability of the colored polycarbonate resin laminate obtained by doing so can be more sufficiently improved.

Examples thereof include a method of thermocompression bonding with a laminating machine, a press machine, etc., and a method of thermocompression bonding with a polycarbonate resin plate in a molten state immediately after extrusion, and a method of thermocompression bonding with a polycarbonate resin plate immediately after extrusion is particularly preferable. The thermocompression bonding conditions differ depending on the type, thickness, and condition of the pressure bonding surface of the polycarbonate resin plate or the film to be thermocompression bonded, and cannot be specified unconditionally, but it is usually near the second transition temperature of the colored film to be thermocompression bonded or higher. 0.03kg
