In the method of laminating a decorative metal film solenostoma the invention the polymer of the alignment film is first laminated on the base material of the resin using the method of polymerization by vapor deposition.

The deposition rate of the polymer of the alignment film is not specifically limited and is preferably equal to 0.5 μm/min or more.

The polymeric material of the alignment film is not specifically limited, provided that it can be deposited by polymerization of deposition from the vapor phase. Examples of such materials include polyurea, polyimide, polyamide, polyoxadiazole, polyurethane and polyazomethine. Among them polyurea is preferred because of its excellent protection properties of the base material of resin.

Polyurea can be obtained by polymerization vapor deposition aromatic alkyl, alicyclic or Monomeric aliphatic diisocyanate and aromatic alkyl, alicyclic or Monomeric aliphatic diamine.

Monomeric isocyanate for the source materials may represent, for example, aromatic alkalisation represented by chemical formula 1, alicyclic diisocyanate represented by the chemical formula 2, or an aliphatic diisocyanate represented by the chemical formula 3.

The alignment film of polyurea can be obtained by evaporation of the starting monomers in vacuum and polymerization of the monomers on the substrate from the resin. Vacuum pressure is not specifically limited and may be about 10 to 100 PA.

Specific examples of the original monomers are the following.

<a Diisocyanate>
