Patent ID: 11701803

Abstract:
A method for producing a press-molded body of a polycarbonate sheet including resin layers (A) and (B) respectively containing a polycarbonate resin, and a high hardness resin (B) and a hard coat layer (C) sequentially stacked on at least one surface of the resin layer (A). The method includes pre-heating the polycarbonate sheet to a temperature between a glass transition point of the resin layer (A)−45° C. or higher and the glass transition point or lower; locating the pre-heated polycarbonate sheet between an upper and lower die of a mold, wherein a time period after the pre-heating is finished until the polycarbonate sheet is located between the upper and lower die of the mold is 90 seconds or shorter; and clamping the mold to press the upper and lower die to obtain the press-molded body of the polycarbonate sheet.
