Biaxially oriented polyester film, process for producing the same, and use thereof as substrate for photographic sensitive material

A silicone adhesive film comprising (A) a biaxially oriented aromatic polyester film, and (B) a crosslinked primer layer which is present on at least one surface of the aromatic polyester film and is formed of a crosslinked polymer of (a) alkoxysilane having a functional group selected from the group consisting of an epoxy group, vinyl group and mercaptoalkyl group and (b) alkoxysilane having an amino group; a production method thereof; and a release film.

Silicone adhesive film

An adherent polyester film laminate (A) having a coating layer of a composition formed on one side or both sides of a polyester film, the composition comprising, as main components, (i) an aqueous polyester having a secondary transition point of 40 to 85.degree. C. and (ii) a fatty acid bisamide; a polyester film laminate (B) having a hard coat layer formed on the coating layer of the laminate (A); and a polyester film laminate (C) having an anti-reflection layer formed on the hard coat layer of the laminate (B). Since these laminates are excellent in adhesive force, transparency and slipperiness and has an anti-reflection property, they are useful as a face surface protective material for glass and displays.

Adherent polyester film laminate

An antistatic polyester film having formed on at least one side of a polyester film a coating layer which consists essentially of (a) 5 to 40% by weight of a phosphoric acid ester salt-based antistatic agent, (b) 1 to 20% by weight of a surfactant having an HLB value of 12 or less, (c) 40 to 90% by weight of at least one binder selected from acrylic copolymers and polyester copolymers, and (d) 3 to 25% by weight of fine particles having an average particle diameter of 10 to 500 nm and which has an extremely uniform surface. This film is excellent in anti-blocking properties at a high humidity and antistatic properties at a low humidity.

Antistatic polyester film

A thermal-transfer recording sheet of an aromatic polyester film, wherein at least one surface of said sheet has, as a thermal-transfer ink receiving layer, a coating of a composition comprising (1) a copolyester, (2) a polyolefin fine particle filler and (3) an antistatic compound selected from the group consisting of organic titanate and organic zirconate. The above thermal-transfer recording sheet exhibits excellent adhesion to heat-melting inks and excellent capability of receiving heat-melting ink layers and has good antistatic properties.
