NOVELTY - An organic-inorganic hybrid material is obtained by simultaneously carrying out hydrolysis of a polymer (1), and hydrolysis and polycondensation of a metal alkoxide by sol-gel method.    USE - For manufacturing organic-inorganic hybrid material for gas-barrier laminated film used in image display device (all claimed) and organic electroluminescent elements as base film or protective film, in substrates useful as electrode substrates of touch panels, electromagnetic-shielding boards of CRTs, plasma display panels, backlights, light-guide plates, color filters, light guards, light tapes, optical disks, solar cells, and active elements, and for packaging materials of foodstuffs and pharmaceuticals.    ADVANTAGE - The manufacturing method provides organic-inorganic hybrid materials having excellent gas barrier property and durability, even under high temperature and humidity conditions. The laminated films obtained using the hybrid material have excellent crack resistance. The hybrid material can be coated by curtain flow coat, dip coat, spin coat, or roll coat. The hybrid material provides laminated films, which provide highly durable image display devices.    DETAILED DESCRIPTION - An organic-inorganic hybrid material is obtained by simultaneously carrying out hydrolysis of a polymer of formula (1), and hydrolysis and polycondensation of a metal alkoxide by sol-gel method.    L and Z = H, linear, branched or cyclic alkyl, or optionally substituted aralkyl;    A = repeating unit derived from ethylenically unsaturated monomer;    a = 30-100 mol%;    b = 0-70 mol%; and    c = 0-30 mol%.    L and Z may couple together to form 5- or 6-membered ring. a, b and c express co-polymerization ratio.    INDEPENDENT CLAIMS are included for the following:    (1) organic-inorganic hybrid material;    (2) gas-barrier laminated film having a layer consisting of the organic-inorganic hybrid material, laminated on a base film; and    (3) image display device having the gas-barrier laminated film.
