Thermosetting resin composition for coating metal thin film and metal laminate using the same

A thermosetting resin composition for coating a metal film comprising:

• an amine compound containing at least one functional group selected from the group consisting of a sulfone group, a carbonyl group, a halogen group, an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, a heteroaryl group having 2 to 30 carbon atoms, and an alkylene group having 1 to 20 carbon atoms;
• a binder resin containing an epoxy resin and a bismaleimide resin;
• an inorganic filler;
• and
• a rubber-based component,
• wherein the rubber-based component includes at least one selected from the group consisting of a styrene-butadiene-based rubber, a neoprene-based rubber, a nitrile-based rubber, a butyl-based rubber, a butadiene-based rubber, an ethylene propylene-based rubber, a silicone-based rubber, a urethane-based rubber, and an acrylic-based rubber,
• the rubber-based component is contained in an amount of at least 5 parts by weight and less than 40 parts by weight, based on 100 parts by weight in total of the amine compound and the binder resin, and
• the thermosetting resin composition satisfies the condition of a complex viscosity of 3500 Pa·s or less in the range in which the rheometer lowest viscosity window is 90 to 180° C.
