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.

Colorant for thermoplastic resin and uses thereof

A process for the production of a colored resin composition, comprising a step (A) of producing an aqueous slurry of a pigment, a step (B) of producing a melting composition of metallocene type polyolefin containing a dispersant and a solvent, a step (C) of kneading the aqueous slurry obtained in the step (A) with the melting composition obtained in the step (B) and a step (D) of removing the solvent and the water from the kneaded mixture obtained in the step (C), a colored composition obtained in the above process has excellent in pigment dispersibility and high color developing properties, a colored resin molded article obtained from the colored resin composition do not give a physical-properties inhibition of 5% or higher and has a color developing properties.

Process for producing colored resin composition and utilization thereof

Coloring resin composition and molded articles

A molded article or water-supply pipe free from causing dot-like projections or small-diameter blisters on the molded article surface when the molded article is brought into contact with chlorine-containing water is obtained from a resin composition containing a polyolefin resin, a pigment and a copolymer resin obtained from a monomer having an .alpha.,.beta.-unsaturated double bond and a dibasic acid having an unsaturated double bond or an anhydride thereof.

Colorant resin composition

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.

Process for preparing resin composition for coloring and a resin

An infiltration-type water-based organosilicon composition having excellent performance as a water absorption preventer for construction materials and being stable as an emulsion, which is prepared by emulsifying alkylalkoxysilane and/or its condensate in water in the presence of (a) an anionic emulsifier and/or nonionic emulsifier, (b) a thickener, and (c) an alkaline compound.
