In a gas-barrier aluminum deposition film according to one embodiment of the present invention, a seed coating layer containing functional groups of at least one type selected from among a hydroxyl group (—OH), an amine group (—NH), and a carboxylic acid group (—COOH) is formed on a thermoplastic plastic base film to form a seed molecular layer that enables uniform deposition of aluminum, such as AlOx or AlNx, through chemical reaction, on a surface of the coating layer, with aluminum atoms vaporized at the initial stage of aluminum deposition, thereby inducing uniform deposition of an aluminum layer to be subsequently deposited. Therefore, it is possible to provide a deposited film having superior oxygen and water vapor barrier properties compared to existing aluminum deposition films.

This optical laminate includes a transparent substrate, an optical functional layer, and an antifouling layer laminated in this order, wherein the optical functional layer is a laminate in which a low refractive index layer and a high refractive index layer are alternately laminated, the antifouling layer is formed of a vapor-deposited film obtained by vapor deposition of an antifouling material, and the residual amount of fluorine atoms in the antifouling layer detected by XRF after 10 minutes of cleaning by irradiation with 40 KHz and 240 W ultrasonic waves in a fluorine-based solvent is 70% or more.
