NOVELTY - A composition contains a product (a) obtained by partially hydrolyzing organozinc compound contained in solutions (S1) and (S2). The solution (S1) is obtained by dissolving organozinc compound (I) in electron-donating organic solvent (b1). The solution (S2) is obtained by dissolving organozinc compound (I) and group 3A element compound(s) (II) or (III) in organic solvent (b1), and contains water.    USE - Composition is used for manufacture of zinc oxide film (claimed). Uses include but are not limited to photocatalyst film, ultraviolet protection film, infrared relfectiveness film, electrode film of dye-sensitized solar cell, window glass, imaging device, cover glass for timepiece, antistatic film, light emitting element, and thin-film transistor.    ADVANTAGE - The composition has excellent handleability, and does not have ignition quality.    DETAILED DESCRIPTION - A composition contains a product (a) obtained by partially hydrolyzing organozinc compound contained in solutions (S1) and (S2). The solution (S1) is obtained by dissolving organozinc compound of formula: R1-Zn-R1 (I) in electron-donating organic solvent (b1). The solution (S2) is obtained by dissolving organozinc compound (I) and 3B group element compound(s) of formulae: McXd.aH2O (II) or R2-M(R4)-R3.(L)n (III) in organic solvent (b1), and contains water.    R1 = 1-7C linear or branched alkyl;    c = 1 or 2;    M = group 3A element;    X = halo, nitric acid or sulfuric acid, preferably halo or nitric acid;    d = 3;    a = 0-9;    R2-R4 = H, linear or branched 1-7C alkyl, linear or branched 1-7C alkoxy, carboxylic acid group or acetylacetonato;    L = coordinating organic compound containing N, O or P;and    n = 0-9.    When X is sulfuric acid, then c is 2. INDEPENDENT CLAIMS are included for the following:    (1) manufacture of zinc oxide film, which involves coating the composition on the surface of a substrate, heating obtained coating film at 300 degrees C, and doping 3B group element; and    (2) zinc oxide film, which has average transmittance of 80% or more with respect to visible ray.
