<p>PURPOSE:To obtain the titled filter having an excellent spectral characteristics by incorporating to said filter, a green coloring matter formed with vapor- depositing a coloring matter of an octa-4,5-phenylphthalocyanine. CONSTITUTION:The titled filter has the green coloring matter formed by vapor- depositing the octa-4,5-phenylphthalocyanine type coloring matter. As the green coloring matter layer is composed of the vapor-deposited layer of said phthalocyanine type coloring matter, the filter having an excellent heat resistance and solvent resistance properties and a good spectral property as green color is obtd. The filter is prepared by forming a resist pattern 2 on the substrata 1 and by irradiating on a whole surface of the resist pattern 2, a light or an electron beam having a sensitivity against the resist followed by vapor- deposition octa-4,5-phenylphthalocyanine or its complex salt of metal by means of a vacuum-deposition method on the surface of the substrate 1 arranging the resist pattern thereon to form the layer 3 of the coloring matter. The green coloring matter layer 4 having a stripe pattern is formed by dipping the layer 3 in a solvent.</p> |
