In a nuclear power plant, a corrosion-resistant oxide film on a surface of the metal component of a reactor structure is exposed to a high-temperature water, the corrosion-resistant oxide film containing an oxide having a property of a P-type semiconductor, and a catalytic substance having a property of an N-type semiconductor is deposited on the oxide film. The oxide film maintains the property of the P-type semiconductor.

It is an object of the present invention to provide a thermoplastic resin coloring agent having excellent dispersibility, transparency, ultraviolet blocking properties, etc., and a thermoplastic resin composition employing same, and it is another object of the present invention to provide a thermoplastic resin molding having excellent dispersibility, transparency, ultraviolet blocking properties, stretchability, and surface smoothness. The present invention relates to a thermoplastic resin coloring agent containing a surface-treated &#x3b1;-ferric oxide (A) formed by coating a non-acicular &#x3b1;-ferric oxide having an average particle size of 0.01 to 0.06 &#x3bc;m and an aspect ratio of 0.2 to 1.0 with a polyhydric alcohol and an organopolysiloxane, and an oxycarboxylic acid metal salt (B1) as a dispersing agent (B) and, moreover, to the thermoplastic resin coloring agent further containing a methine-based dye (C). The present invention also relates to a thermoplastic resin composition and a molding obtained using the thermoplastic resin coloring agent. Furthermore, the present invention relates to a molding obtained by coating the molding with a carbon film.

A process is provided for preparing a resin composition for coloring which comprises the steps of a phase replacement and dehydration of a pigment (a); water (b); a thermoplastic resin (c), an aqueous dispersion or solution of a thermoplastic resin (d) or an aqueous compound (e) in a twin screw extruder. Also, there is provided a resin composition for coloring prepared by such a process. It is possible to efficiently manufacture a resin composition for coloring (master batch) which has excellent pigment dispersibility and which is capable of uniform coloring without causing color unevenness.
