NOVELTY - A gas barrier film (1) has a gas barrier resin layer (20) and an inorganic compound film (30) sequentially provided on a base material consisting of a synthetic resin film. The resin layer contains tricyclo ring compound or compound derived from tricyclo ring compound (I). The resin layer is formed by irradiating an active energy ray to a hybrid type composition containing alkoxysilane composition comprising alkoxysilane (A) (II) and alkoxysilane (B) (III), carrying out radical polymerization, hydrolyzing and condensing by hydration.    USE - Gas barrier film. Uses include but are not limited to packaging material of foodstuffs, industrial products and pharmaceuticals, solar cell module, liquid crystal display panel, organic electroluminescent display panel, back surface side protection sheet of touch panel, etc.    ADVANTAGE - The gas barrier film has excellent barrier property with respect to oxygen and water vapor, flexibility, bending resistance and exterior.    DETAILED DESCRIPTION - A gas barrier film (1) has a gas barrier resin layer (20) and an inorganic compound film (30) sequentially provided on a base material consisting of a synthetic resin film. The resin layer contains tricyclo ring compound or compound derived from tricyclo ring compound of formula (I). The resin layer is formed by irradiating an active energy ray to a hybrid type composition containing alkoxysilane composition comprising alkoxysilane (A) of formula (II) and alkoxysilane (B) of formula (III), carrying out radical polymerization, hydrolyzing and condensing by hydration.    R=H or methyl;    Z=4-9C (meth)acryloxyalkyl or vinyl;    Y1=1-4C alkyl;    R1,R4,R5=1-8C alkyl;    m=1-5;    n=0-2;and    p=0-2.    An INDEPENDENT CLAIM is included for manufacture of gas barrier film, which involves applying hybrid type composition on the base material, radically polymerizing by irradiating active energy ray, forming gas barrier resin layer by condensing the hybrid type composition by hydration, and forming inorganic compound film on gas barrier resin layer.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of gas barrier film.    Gas-barrier film (1)    Base material (10)    Gas-barrier resin layer (20)    Inorganic compound film (30)
