PURPOSE:To prepare the title compsn. giving a film excellent in slip properties, abrasion resistance, and scratch resistance by compounding a specific polyester, a specific particulate divinylbenzene-ethylvinylbenzene copolymer, and a specific particulate branched linear colloidal silica. CONSTITUTION:The title compsn. comprises a polyester obtd. by reacting a dicarboxylic acid component mainly consisting of an arom. dicarboxylic acid with a glycol component, a particulate divinylbenzene-ethylvinyl benzene copolymer having a mean particle diameter of 0.01-5mu, and a particulate branched linear colloidal silica having a ratio (D1/D2) of a particle diameter measured by the dynamic light scattering method (D1mmu) to that measured by the nitrogen gas adsorption method (D2mmu) of 2 or higher, D1 being 60-600mmu, and particle diameters observed under an electron microscope of 41-100mmu. The compsn. is formed into a film suitable for photography, printing plate making, use as a capacitor, etc. |
