Document Type and Number:
WIPO Patent Application WO/2017/061415
Kind Code:
A1
Abstract:
The present invention is a polyester composition for master batches, which contains prescribed amounts of: a polyester having a dicarboxylic acid component and a glycol component as constituents; a magnesium compound; an alkali metal compound; a specific phosphorous compound; and a lubricant, and which has a sufficiently low melt resistivity and is excellent in hue and thermal stability. Adding this polyester composition for master batches enables enhancing of electrostatic adhesion to a cooling drum so as to improve film formation properties, and imparting of optimum slippage, thereby providing a polyester film that also has excellent quality.
