  • Patent number: 6577446
    Abstract: A coloring structure includes a light-reflecting base, a brilliant layer placed on the base, and transparent brilliant units contained in the brilliant layer, each brilliant unit including an alternate lamination of at least two polymers having different refractive indexes, the lamination producing interfered light resulting from reflection and interference of light and transmitted light resulting from transmission of light, each brilliant unit controlling interfered and transmitted lights. The coloring structure is provided with a coloring mechanism for producing at least an interference color resulting from interfered light, a first object color resulting from reflection of transmitted light produced by the base, and a second object color resulting from reflection of incident light produced by the base without striking any brilliant units.

  • Patent number: 6537673
    Abstract: An infrared transmitting film includes a mirror-coat layer having a lamination of high-refractive-index material layers and low-refractive-index material layers, and a color-material layer placed on the mirror-coat layer and for absorbing visible light in a given wavelength range and transmitting infrared ray. The film has 80% or more transmission factor for infrared ray.

  • Patent number: 6490090
    Abstract: A coloring structure includes a surface layer placed on a base with light transparency and containing transparent brilliant members, each brilliant member including an alternate lamination of at least two polymers having different refractive indexes, and controlling interfered light resulting from reflection and interference produced by the alternate lamination and transmitted light other than interfered light and passing through the alternate lamination. The brilliant members may dispersedly be contained in the base.

  • Patent number: 6350509
    Abstract: A coating structure includes a color base, a first coating layer placed on the color base, and transparent brilliant members contained in the first coating layer, each brilliant member including an alternate lamination of at least two polymers having different refractive indexes and controlling interference light resulting from reflection and interference produced by the alternate lamination and transmitted light other than interference light. The coating structure is provided with a coloring mechanism for producing at least an interference color resulting from reflection and interference of an incident source spectrum produced by the brilliant members, a first object color resulting from direct action of the spectrum with the color base, and a second object color resulting from action of the spectrum transmitting through the brilliant members with the color base. Mixing of the three colors causes a hue varying with the angle.
