料によって着色されている。2. Description of the Related Art Conventionally, hydrogen peroxide solution has been used for bleaching clothes. This hydrogen peroxide solution is usually filled in a plastic container such as polyethylene having a high sealing property and is commercially available as a household liquid bleaching agent. Further, this plastic container is colored with a pigment in order to protect the contents and design.

ップになるという問題が生じた。It is known that hydrogen peroxide water is decomposed using various substances such as fine powder, solid having a rough surface, and metal as a catalyst to generate oxygen gas. . Therefore, when a plastic container containing a hydrogen peroxide aqueous liquid bleaching agent is colored with titanium dioxide or the like, the hydrogen peroxide aqueous solution is decomposed to generate oxygen gas, and the bleaching ability of the hydrogen peroxide aqueous solution is significantly reduced. Furthermore, depending on the gas generated,
There was a problem that the container was deformed. For this problem,
A container having a multi-layered structure having an uncolored resin layer inside is used as a container for storing hydrogen peroxide water. However, the multi-layered container has a problem that the manufacturing process is complicated and the cost is increased.

Coating with a hydrous oxide of aluminum and / or silicon,
Further, it is described that decomposition of hydrogen peroxide solution can be prevented by using titanium dioxide having a pH of 2 to 5 which is treated with an acid. However, the acid-coated titanium dioxide described in the publication has problems that it is inferior in dispersibility and that the acid volatilizes due to the heat during processing due to the acidity, corroding the mold and the processing machine. As a result of intensive studies, the present inventors have found that an inorganic pigment whose surface is coated with an inorganic surface treatment agent and an organic surface treatment agent has excellent dispersibility and suppresses decomposition of hydrogen peroxide solution.
The inventors have found that it can be prevented and have reached the present invention.

効果はほとんど変わらなくなる。Since weathering and yellowing resistance tend to be insufficient only by treatment with methylhydrogenpolysiloxane, it is preferable to use 0.01 part by weight or more of alumina based on 100 parts by weight of titanium oxide. On the other hand, even if more than 2 parts by weight of alumina is used with respect to 100 parts by weight of titanium oxide,
The effect of suppressing or preventing the decomposition of hydrogen peroxide is almost unchanged. Also, with respect to 100 parts by weight of titanium oxide,
When the amount of methylhydrogenpolysiloxane is less than 0.01 part by weight, the dispersibility becomes insufficient and the titanium oxide 100
Even if more than 1 part by weight of methylhydrogenpolysiloxane is used with respect to parts by weight, the effect of suppressing / preventing decomposition of hydrogen peroxide remains almost unchanged.
