2. Description of the Related Art The resin to be colored in the present invention is a resin mainly composed of an ethylene / propylene-block copolymer which may contain an inorganic filler (generally talc or the like). Characterized by its large size, it is widely used in automobile parts, home appliances, and other necessary molded products. Carbon black and titanium dioxide are generally used as coloring pigments for coloring polyolefin resins such as polyethylene and polypropylene resins from black to gray. Among the pigments, carbon black and titanium dioxide are particularly used in large amounts because they have excellent coloring power and are economically inexpensive.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention Generally, ethylene-propylene containing 0 to 40 parts by weight of an inorganic filler is used.
In order to color the resin mainly composed of the block copolymer from black to gray, ordinary carbon black and titanium dioxide are blended and melt-extruded and pelletized. However, when these pellets are subjected to extrusion molding machines or injection molding machines and molded into molded products, due to the anisotropy of the flow direction of the molten resin during molding, they are not partially colored and the surface of the molded product is streaked. There was a defect that color irregularity (color separation) that turned white or band-shaped was observed. It should be noted that this color unevenness (color separation) is generated in almost the same place of the molded product, which is different from general color unevenness of the colorants (insufficient mixing). In order to prevent the occurrence of color unevenness (color separation), for example, ethylene
A method has been proposed in which iron black is used instead of carbon black in black coloring of a resin mainly composed of a propylene-block copolymer (Japanese Patent Publication No. 62-14576).

However, iron black has a lower coloring density than carbon black. Therefore, in order to obtain the same coloring density as carbon black, about 7 times that of carbon black is required.
-10 times more iron black is needed. As a result, when coloring a composite material mainly composed of an ethylene / propylene-block copolymer, the cost of the colorant is high, and when a large amount of iron black is used, the impact resistance is high. There is a drawback that the strength of the resin molded product mainly composed of the block copolymer is impaired. Therefore, an object of the present invention is to prevent the deterioration of the physical properties of the resin when coloring the resin mainly composed of ethylene / propylene-block copolymer with carbon black and titanium dioxide, and also to use it together with the inorganic filler. , Color unevenness (color separation)
It is an object of the present invention to provide a resin coloring composition that can be colored and molded without any treatment.
