Abstract
A minute structure for producing a color comprises a first coloring part for producing a color with first wavelengths in the visible light area by physical actions such as reflection and Interference. The first coloring part includes lamellas disposed in layers at predetermined intervals. A second coloring part is disposed adjacent to the first coloring part for absorbing a part of light with second wavelengths in the visible light area and reflecting the rest of light. The second coloring part contains a coloring matter.
Claims22
A minute structure for producing a color, comprising:
- at least one first part, said first part producing a first color with first wavelengths in a visible light area by physical actions, said first part including lamellas disposed in layers at predetermined intervals;
- and
- a second part disposed adjacent to said first part, said second part absorbing a part of light with second wavelengths in said visible light area and reflecting the rest of light, said second part comprising a coloring compound.
A minute structure for producing a color, comprising:
- at least one first part, each first part producing a first color with first wavelengths in visible light by at least one of reflection, interference, diffraction or light scattering, each first part including lamellas disposed in layers at predetermined intervals;
- and
- a second part disposed adjacent to said first part, said second part absorbing light possessing second wavelengths in said visible light and reflecting light not possessing said second wavelength, said second part comprising a coloring compound,
- said first parts being radially disposed around said second part.
A minute structure for producing a color, comprising:
- means for producing a first color with first wavelengths in a visible light area by physical actions, said producing means including lamellas disposed in layers at predetermined intervals;
- and
- means disposed adjacent to said producing means for absorbing a part of light with second wavelengths in said visible light area and reflecting the rest of light, said absorbing means containing a coloring compound.
A minute structure which is capable of producing a compound color comprising:
- a first coloring part producing a first color,
- a second part adjacent to said first part and comprising a chromatic coloring compound which reflects light at particular wavelengths, said second part being configured such that when said stray light emitted from said first part penetrates said second part, at least a portion of said stray light is emitted at a wavelength of said chromatic coloring compound to produce a second color.
