PROBLEM TO BE SOLVED: To provide an antistatic resin molding in which both antistatic property and transparency are substantially improved rather than not deteriorated by hot-molding (secondary molding), and to provide a secondary molding formed by further hot-molding. SOLUTION: The molding comprises a transparent antistatic layer of thermoplastic resin having thickness of 0.15-3.5μm in which entangling ultrafine long carbon fibers 2-15 wt.% with a wire diameter 100 nm or less and an aspect ratio not less than 5 is contained in a surface of a transparent base material of the thermoplastic resin. Surface resistivity of the antistatic layer after hot-molding at molding magnification of 3 becomes not more than the surface resistivity of the antistatic layer before hot-molding. Total light transmittance is more than 60% when hot-molded further at the molding magnification of 1.1-10, and the haze is not more than 20%, and the surface resistivity of the antistatic layer is less than 10<SP>12</SP>Ω/SQUARE. The secondary molding is formed by further hot-molding the antistatic resin molding at the molding magnification of 1.1-10. COPYRIGHT: (C)2008,JPO&INPIT |
