Abstract: PURPOSE:To obtain the title film improved in adhesion to ink, humidity-resistant adhesion, durability and blocking resistance by forming a surface modifying layer based on an aqueous self-emulsifiable heat-reactive urethane on a polyester film. CONSTITUTION:An unstretched sheet of a polyester (e.g. polyethylene terephthalate) of an intrinsic viscosity of 0.5 or above is stretched at 70-120 deg.C at a stretch ratio of 2.0-5.0 to obtain a film of a centerline average roughness of 0.02-0.5mum. A coating material based on an aqueous self-emulsifiable heat- reactive urethane of a degree of swelling by solvent of 50% or below and a degree of swelling by water of 80% or below is applied to at least either surface of this film in a thickness of 0.001-3.0mum and dried to form a surface-modifying layer thereon. This film is simultaneously or consecutively stretched at 70-150 deg.C at a stretch ratio in the machine direction of 2.0-5.0 and a stretch ratio in the transverse direction of 2.0-5.0. This stretched film is further heat-treated at 150-240 deg.C for 1-60sec while a relaxation of 0.10% is optionally given thereto.

Abstract: PURPOSE:To obtain a laminated film being excellent in flexibility, material to be applied by durability and adhesion strength to a providing as an intermediate layer a composition layer formed of a specific graft copolymer and a crosslinking agent. CONSTITUTION:A laminate is formed of a polyester film A, a resin layer B which is laminated at least on one surface of the polyester film A, whose main constituents are a copolymer obtained by grafting a compound having an unsaturated bond onto hydrophilic-group-containing polyester resin and a crosslinking agent and wherein the grafting rate of the copolymer is 0.5 to 600%, and an active linear-crosslinked-type acrylic resin layer C. This layer may be formed otherwise, by a chlorine-containing resin layer D or a photosensitive photographic emulsion layer F or an active linear or thermocrosslinked type silicone resin layer G provided on the surface of the resin layer B. When the grafting rate is lower than 0.5%, moisture resistance is deteriorated. When the rate exceeds 600%, application properties are deteriorated and the adhesion strength between a modification layer and a base lowers. When as the crosslinking bonding agent, an isocyanate crosslinking agent, a melamine crosslinking agent, a urea crosslinking agent or an epoxy crosslinking agent is used, a large crosslinking effect is exhibited and is preferable.

Abstract: PURPOSE:To contrive improvements in bondability of the title film to a conductive layer, resistor layer, insulation layer and printing ink layer, by providing a predetermined coating layer on a biaxially stretched polyester film which has been made a specific center line mean roughness. CONSTITUTION:A biaxially stretched polyester film having centerline mean roughness of 0.02-0.50mum is manufactured by adding inorganic particles (a) to polyester. A coating layer on the surface of the film is formed of the inorganic particles (a) and an ingredient mainly composed of a crosslinked polyester copolymer (b). In the case where a crosslinkable polyester copolymer obtained by grafting acrylic macromer as a polyester copolymer (b), it is preferable to use acrylic resin especially aqueous dispersion acrylic resin. It is preferable if a mean particle diameter (D) of the inorganic particles (a) falls within a range of 0.08-2.2mum and D/d falls within a range of 1.1-80 in relation to a thickness (d) of a coating layer. Then, as the coating layer is applied at least to one side of the polyester film, being stretched and heat treatment is performed, it becomes that thin and uniform coating is possible and crosslinking of the polyester copolymer progresses rapidly and highly.
