Abstract
Abstract A film forming method, a recording medium formed thereby, and a recording method therewith are provided. The recording medium comprises a recording layer constituted of a monomolecular film or monomolecular-layer built-up film of a clathrate complex compound comprised of a host molecule and a guest molecule, said host molecule having a hydrophilic portion, a hydrophobic portion, and a portion capable of enclosing said guest molecule.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
85 words
A method for forming a monomolecular film or monomolecular-layer built-up film of a clathrate complex compound, which comprises; dissolving host molecules having a hydrophilic portion, a hydrophobic portion, and a portion capable of enclosing guest molecules together with the guest molecules, in a solvent; extending the resulting solution on a water surface to form a monomolecular layer of the clathrate complex compound composed of said host and guest molecules; and transferring said layer onto a substrate to form the intended monomolecular film or built-up film.
Claim 2
Independent Claim
85 words
A method for forming a monomolecular film or monomolecular-layer built-up film of a clathrate complex compound, which comprises; dissolving host molecules having a hydrophilic portion, a hydrophobic portion, and a portion capable of enclosing guest molecules together with the guest molecules, in a solvent; extending the resulting solution on a water surface to form a monomolecular layer of the clathrate complex compound composed of said host and guest molecules; and transferring said layer onto a substrate to form the intended monomolecular film or built-up film.
Claim 3
Dependent Claim
26 words
The film forming method of claim 1, wherein the substrate is formed of the material selected from the group consisting of glass, aluminum, plastics, and ceramics.
Claim 4
Independent Claim
98 words
A method for forming a monomolecular film or monomolecular-layer built-up film of a clathrate complex compound, which comprises; dissolving host molecules together with or without guest molecules in a solvent, said host molecules having a hydrophilic portion, a hydrophobic portion, and a portion capable of enclosing the guest molecule; extending the resulting solution on the surface of an aqueous solution of water soluble guest molecules to form a monomolecular layer of a clathrate complex compound composed of said host and guest molecules; and transferring said layer onto a substrate to form a monomolecular film or a built-up film.
Claim 5
Independent Claim
98 words
A method for forming a monomolecular film or monomolecular-layer built-up film of a clathrate complex compound, which comprises; dissolving host molecules together with or without guest molecules in a solvent, said host molecules having a hydrophilic portion, a hydrophobic portion, and a portion capable of enclosing the guest molecule; extending the resulting solution on the surface of an aqueous solution of water soluble guest molecules to form a monomolecular layer of a clathrate complex compound composed of said host and guest molecules; and transferring said layer onto a substrate to form a monomolecular film or a built-up film.
Claim 6
Dependent Claim
26 words
The film forming method of claim 3, wherein the substrate is formed of the material selected from the group consisting of glass, aluminum, plastics, or ceramics.
Claim 7
Dependent Claim
25 words
The film forming method of claim 3, wherein said layer is transferred to the substrate in an atmosphere of gas of the guest molecule compound.
