物に関する。The present invention relates to a colored resin composition for a colored resin molded article which comes into direct contact with chlorine-containing water.
More specifically, the present invention relates to a colored resin composition that can provide a molded article that does not generate water bubbles on the surface of the molded article even when the molded article is in direct contact with chlorine-containing water.

するという問題が生じていた。2. Description of the Related Art Various pigments have been used for coloring and molding polyolefin resins such as polyethylene and polypropylene. However, when the molded article comes into direct contact with chlorine-containing water, for example, when used for water supply pipes, water bubbles are generated on the surface of the molded article, the water bubbles are peeled off, and the peeled molded article is formed. However, there has been a problem that a part of the water is mixed into the clean water.

れている。In the case of water supply pipes in particular, strict standards are required for the generation of water bubbles and peeling of water bubbles (partial mixing of molded products) due to the property that tap water is used for eating and drinking. Therefore, a two-layer tube has been proposed in which a layer containing no pigment is provided on the inner surface that directly contacts the chlorine-containing water, and a layer containing the pigment is provided on the outer surface. However, such a two-layer tube has problems that it is more difficult to manufacture than a single-layer tube and requires a special molding machine. In addition, since the joint part connecting the pipes is difficult to have a two-layer structure,
There is a demand for a colored resin composition having excellent chlorine-containing water resistance even in a single layer.
