    Abstract: The invention provides a laminated film that has, when being formed as a gas-barrier laminated film provided with an inorganic thin film layer, excellent oxygen gas barrier properties and adhesion between respective layers under normal conditions and, even after being subjected to a moist heat treatment, has good adhesion even when subjected to processing such as printing or lamination The laminated film has (a) a covering layer on at least one surface of a substrate film, wherein the covering layer contains a covering layer resin composition with a resin having an oxazoline group as a constituent component, (b) an inorganic thin film layer on the covering layer, and (c) a protective layer that has a urethane resin and an arithmetic mean roughness of 0.5-2.0 nm in a 2-μm square and is on the inorganic thin film layer. The laminated film has a surface hardness of 350-700 N/mm2.

    Abstract: Provided is an aqueous coating composition capable of forming a coating film having superior metallic coating film appearance and coating film properties and reducing the amount of an organic solvent to be used. Also provided is a method for forming a metallic coating film using such an aqueous coating composition. Provided is an aqueous coating composition comprising a coating film-forming resin, a curing agent, a scaly pigment, an inorganic viscosity agent, a hydrophobic associative viscosity agent, and a dispersant, wherein the composition contains the inorganic viscosity agent in an amount of 1 to 7 parts by mass based on 100 parts by mass of the total resin solid content of the coating film-forming resin and the curing agent, and the composition contains the hydrophobic associative viscosity agent in an amount of 1 to 15 parts by mass based on 100 parts by mass of the total resin solid content of the coating film-forming resin and the curing agent.

    Abstract: Described herein is an anti-rust composition for metal surfaces including: a) 30% to 80% by weight of water-soluble or water-dispersible acrylic resin and/or urethane resin; b) 0.1% to 10% by weight of epoxysilane and/or vinylsilane; c) 0.1% to 3% by weight of silicone surfactant and/or fluorosurfactant; d) 0.1% to 10% by weight of alcohol and/or ether; and e) water, where the weight percentage of each component is based on the total weight of the aqueous composition. Also described herein is an anti-rust treatment method on a metal surface including steps of i) coating the invented anti-rust composition onto the metal surface and ii) drying the coating layer at a temperature from 60° C. to 150° C. Also described herein is an anti-rust treated coil steel obtained by the anti-rust treatment method.
