Abstract: 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.

Abstract: The invention relates to a novel amino acid silicon polymer with good adhesion to the keratin layer of the skin, a method of preparing the amino acid silicon polymer, a cosmetic particles surface-treated with the amino acid silicon polymer, and a color cosmetic composition including the cosmetic particles. According to the present invention, the particles surface-treated up to 3% to the maximum with the amino acid silicon polymer prepared by reacting an amino acid and a functional silicon polymer in the manner of organic synthesis have water resistance and usability peculiar to silicon-treated pigments and take positive surface charges, thereby offering good adhesion to the skin and durability. Due to these characteristics, the cosmetic containing the surface-treated particles of the present invention is superior in the cosmetic effect to that containing the conventional surface-treated particles.
