NOVELTY - A hydrophilic film formation composition comprises hydrophilic polymer which has hydrolyzable alkoxy silyl group(s) to polymer terminal or side chain, metal complex catalyst and surfactant which has hydrolyzable alkoxy silyl group(s) and reacting functional group in molecule.    USE - A hydrophilic film formation composition for hydrophilic material and fin material used for heat exchanger for air-conditioner (claimed) e.g. room air-conditioner, package air-conditioner and car air-conditioner. Can also be used for cooler of room interior, oil cooler for construction machines, radiator of motor vehicle and capacitor, transparent glass substrate or transparent plastic substrate, lens (e.g. eyeglass lens, optical lens, camera lens, endoscope lens, lens for illumination, lens for semiconductors and lens for copying machines), prism, mirror (e.g. rear-view mirror and window glass for vehicles, mirror for bathrooms, mirror for washrooms, dental mirror and road mirror), glass (e.g. soda glass, lead glass, borosilicate glass, float plate glass, figured glass, slider glass, wire glass, wire on glass, tempered glass, laminated glass, multi-layer glass, vacuum glass, security glass, highly thermally-insulated low-E multilayer glass, window glass of building or watchtower, glass for building materials, gondola of motor vehicle, rail vehicle, aircraft, vessel, midget submarine, snow vehicle, ropeway, gondola of amusement park, gondola of motor vehicle, rail vehicle, aircraft, vessel, midget submarine, snow vehicle, snowmobile, motorcycle and ropeway, gondola of amusement park and windshield glass of vehicle), goggles for protection, goggles for sports, mask for protection, mask for sports, shield of helmet, glass of frozen food display case, building exterior like building materials, outer wall or roof, building interior equipment, window frame, window glass, structural material, exterior and coating of motor vehicle, rail vehicle, aircraft, vessel, bicycle and motorcycle, exterior of machinery or article, dustproof cover and coating, traffic sign, display devices, exterior and coating of advertising sign, sound insulating wall for roads, sound insulating wall for railways, bridge and guard rail, cover and coating of tunnel interior equipment, insulator, solar cell cover, solar water heater heat collecting cover, vinyl greenhouse, illuminating lamp for vehicles, household equipment, toilet bowl, bathtub, wash stand, lighting fixture, lighting cover, kitchen utensils, tableware, dishwashing device, dish dryer, sink, kitchen range hood, ventilating fan, signboard, vinyl greenhouse, insulator, cover for vehicles, tent material, covers for heat collecting devices, reflecting plate, sliding shutter, screen door, cover for solar cells, solar water heater, street light, pavement, exterior lighting, stone and tile, bridge, greenhouse, artificial waterfall, tile for artificial fountain, sealer, guard rail, veranda, automatic vending machine, air-conditioner outdoor unit, outdoor bench, shutter, tollgate, charge box, roof pipe, lamp protective cover for vehicles, tunnel inner wall, adherable film, emblem, radiation fin for tunnel internal illumination, window sash, air-conditioner indoor unit, mirror for washrooms and bathrooms, vinyl greenhouse ceiling, bathroom vanity unit, motor vehicle body, motor vehicle air-conditioner.    ADVANTAGE - The composition is excellent in hydrophilic sustainability, stain resistance and water resistance on support surfaces.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) hydrophilic material comprising hydrophilic film formation composition which is coated on support body; and    (2) fin material comprising hydrophilic film formation composition which is coated.
