A gas barrier film comprising a resin substrate provided thereon at least one layer of a ceramic film, wherein the density ratio Y (=ρf / ρb) satisfies 1≧Y≧0.95 and the ceramic film has a residual stress being a compression stress of 0.01 MPa or more and 100 Mpa or less, wherein ρf is the density of the ceramic film and ρb is the density of a comparative ceramic film being formed by thermal oxidation or thermal nitridation of a metal as a mother material of the ceramic film so as to being the same composition ratio of the ceramic film.

[Object] In light of the problems in the prior art, an object of the invention is to provide a white laminated polyester film for a reflective plate sheet, which has a high reflectance and a high concealing property compatible with each other, and is not easily broken and is high in productivity.[Solving means] A white laminated polyester film for a reflecting sheet, including a polyester layer (B) containing voids therein, and a polyester layer (A) laminated at least on one surface side of the layer (B), the laminated polyester film satisfying the following (1) to (5): (1) the thickness of the polyester layer (A) laminated at least on one surface side is from 5 to 15 μm; (2) the polyester layer (A) contains therein particles having a refractive index of 2.0 or more in an amount of 3 to 15% by weight of the polyester layer (A); (3) the thickness of the polyester layer (B) is 150 μm or more; (4) the amount of particles having a refractive index of 2.0 or more contained in the polyester layer (B) is 2% or less by weight of the polyester layer (B); and (5) the polyester layer (B) contains therein a resin which is not soluble in polyester resin in an amount of 12 to 25% by weight of the polyester layer (B) and / or inorganic particles having a refractive index less than 2.0 in an amount of 30 to 50% by weight of the polyester layer (B).

The invention concerns transparent, flame retardant, thermoformable, UV-stabilized, single layered or multilayered films, containing a cristallizable thermoplastic material, preferably polyethyleneterephthalate, at least one flame retarding agent and a UV stabilizer as main components. Said films are characterized by good stretchability, thermoformability and good optical and mechanical properties, which makes them and the shaped bodies made from said films suitable for both inner and outer applications.

A water repellent film (200) according to the present invention includes a first layer (10) having a plurality of fine protrusions (100) on the surface thereof, a second layer (20) covering the fine protrusions (100) and having a water repellent property, and a third layer (30) provided on the surface of the first layer (10) on the opposite side of the fine protrusions (100). When a modulus of elasticity of the first layer (10) is defined as E1, a modulus of elasticity of the second layer (20) is defined as E2, and a modulus of elasticity of the third layer (30) is defined as E3, a definition of E2>E1>E3 is fulfilled. Accordingly, the water repellent film having excellent resistance to abrasion in which a fine structure is not easily abraded and damaged by an external friction force or the like can be obtained.
