ロピレングリコールなどが挙げられる。The polyalkylene glycol used to treat talc in the composition of the invention must have a weight average molecular weight of 100 to +000. If the weight average molecular weight is smaller than this, it will be difficult to obtain a sufficient treatment effect on light resistance, and if it is larger than this, it will be difficult to uniformly adsorb onto the talc surface, and similarly, it will be difficult to obtain a sufficient treatment effect on light resistance. It is difficult to recover the processing effect. Examples of such polyalkylene glycols include polyethylene glycol and polypropylene glycol.

が、衝撃・剛性バランス性能が得られやすい帆５〜５μ
ｍが好ましい。In the composition of the present invention, talc treated with polyalkylene glycol is used as component (B). This treatment of talc is carried out, for example, by diluting the polyalkylene glycol with water or lower alcohol and adding it to the talc powder being crushed in a crusher. The amount of polyalkylene glycol used is 0.0 relative to talc.
5 to 5% by weight is preferred. The grinder is preferably one that can be finely ground or finely ground in a dry or semi-dry process, such as a micron mill, a jet airflow grinder, a ball mill,
Examples include micronizers, turbo mills, atomizers, etc., and jet air flow type pulverizers such as macronizer types, impact types, opposed types, and fluidized bed types are preferred from the viewpoint of pulverization efficiency, pulverization time, and workability. This jet stream type mill can adsorb or bond the surface treatment agent onto the surface of the powder by mechanochemical treatment using the impact force generated by the jet air flow. Among these, a fluidized bed method is preferable because the surface treatment is performed uniformly, and this method involves blowing a jet stream onto a mixture of powder and a surface treatment agent at high speed, e.g., 10 to several hundred milliseconds. The particles are collided at a high speed, and the impact causes the powder to be crushed or crushed, and the surface treatment agent is evenly and firmly adsorbed or bonded to the highly surface active surface of the powder. There are no particular restrictions on the average particle size of talc as a final product, but it is 5 to 5 μm, which makes it easy to obtain a good balance between impact and rigidity.
m is preferred.
