PURPOSE:To obtain the title composition which can give a molding low in void content, by dispersing fine metal oxide particles surface-treated with a specified bislactam in a linear saturated polyester. CONSTITUTION:Fine metal oxide particles (a) (e.g., TiO2) are mixed with 1-10wt.% based on component (a), bislactam compound (b) of the formula (wherein X is a bivalent hydrocarbon group), e.g., N,N'-terephthaloylbiscapro lactam, in a solvent [e.g., toluene which can dissolve component (b)] to obtain component B comprising component (a) surface-treated with component (b). Component B is dispersed in a substantially linear saturated polyester (A) (e.g., polyethylene terephthalate). |
