Abstract: PURPOSE:To obtain a slippery film free from falling of particles and scratch defect by providing a composite layer which has both organic particles having a shell-core structure of dimension specified in means particle diameter and water-soluble or water-dispersible resin as a main component on at least one side of a biaxially oriented film. CONSTITUTION:A slippery film is constituted by providing a composite layer which has both organic particles having a shell-core structure of 0.002-8.0mum mean particle diameter and water-soluble or water-dispersible resin as a main component on at least one side of a biaxially oriented film. When the mean particle diameter D is smaller than 0.002mum, slip properties are insufficient. On the other hand, when it is larger than 8.0mum, this case is not preferable because falling of particles is remarkable. When D/T being the ratio of mean particle diameter D of the organic particles and thickness T of the composite layer is regulated within a range of 1.1-80, slippery properties are more enhanced. Further this case is made more preferable because falling of particles is not remarkable. In such a way, since the particles having the shell-core structure are utilized, a flaw and a while spot are drastically reduced without deteriorating slip characteristics. The film good in the surface state can be obtained.

Abstract: PURPOSE:To improve the adhesiveness of a resin layer and a base material film and to improve moisture resistant adhesiveness in particular by applying a water soluble or water dispersible resin on a specific polyester film stretching the film under specific conditions in a uniaxial direction to have the degree of orientation of the resin layer under the specific conditions, and then providing antistatic layer on such layer. CONSTITUTION:A magnetic recording layer is provided on the polyester film which has the composite layer formed by providing the antistatic layer on the water soluble or water dispersible resin layer having 0.03 to 0.6 degree of orientation and 0.001 to 3.0mum thickness on at least one surface and has >=0.5 optical density and >=80% whiteness. The polyester constituting the polyester film to be used consists of at least one kind of structural units selected from ethylene tere-phthalate, etc., as its main constituting component. The cleavage resistance of the resin layer and the adhesiveness, more particularly the moisture resistant adhesiveness of the base material polyester film and the resin layer or the resin layer and the printed layer or the magnetic layer are improved in this way.

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.
