Summary:PURPOSE: A deposition film is provided to maintain the deposition strength to be more than the reference strength after processes with high temperature and high temperature water. CONSTITUTION: A polyurethane coating layer(20) and an aluminum deposition layer(30) are successively stacked on one side of a base film(10). The dried coating thickness of the polyurethane coating layer is between 35 and 50nm using a water-dispersed polyurethane coating composition. The water-dispersed polyurethane coating composition is based on 0.5 to 1.0 weight% of polyurethane resin solid and 0.01 to 0.5 weight% of a silicon-based wetting agent.
