PURPOSE:To get film excellent for slippery and transparency by a method wherein composited material of water insoluble copolyester, soluble organic compound, water, inorganic particle and soluble silicon compound is painted and drawn on the surface of undrawn polyester film which is fluxed and extruded. CONSTITUTION:This film is composed of insoluble polyester copolymerizate which is formed from intermixing dicarboxylic acid component which contains whole dicarboxylic acid and dicarboxylic acid containing 0.5-15mol% sulfonic acid and glycol component A, soluble organic compound of boiling point 60- 200 deg.C B, water C, inorganic particle D and soluble silicon compound E, and the said film is painted water dispension which is composited at the weight ratio of component A/B=100/20-5,000, component B/C=100/50-1,000, component A/C=10,000/0.5-3,000, component A/E=100/0.5-10, and, furthermore, it is biaxially or monoaxially streched. |
