The present invention relates to the use of coating compositions, comprising shaped transition metal, especially silver, particles and a binder, wherein the ratio of pigment to binder is preferably such that the resulting coating shows an angle dependent color change, for the production of security elements and holograms. When the coating compositions of the present invention are used in coating a hologram the obtained products show a an angle dependent color change (flip/flop effect), different colors in reflection and transmission, an extremely bright OVD image and extremely strong rainbow effect, high purity and contrast.

A filler disposition film that can use a commercially procurable filler material having good particle diameter uniformity, enables high positional precision of the filler disposition, can support even an increase in the surface area, and has a prescribed filler regularly disposed in a long resin film. Moreover, the rate of consistency of disposition of the filler in the filler disposition film in rectangular areas of a prescribed size having a length of 1000 times or more the average particle diameter of the prescribed filler, and a width of 0.2 mm or greater is 90% or greater. Such a rectangular area has a long-side direction that is substantially parallel to the long-side direction of the filler disposition film, and a widthwise direction that is substantially parallel to a short-side direction of the filler disposition film. The average particle diameter of the regularly disposed filler is from 0.4 μm to 100 μm.

A versatile silicone resin reflective substrate which exhibits high reflectance of high luminance light from an LED light source over a wide wavelength from short wavelengths of approximately 340-500 nm, which include wavelengths from 380-400 nm near lower limit of the visible region, to longer wavelength in the infra-red region. The silicone resin reflective substrate has a reflective layer which contains a white inorganic filler powder dispersed in a three-dimensional cross linked silicone resin, the inorganic filler powder having a high reflective index than the silicone resin. The reflective layer is formed on a support body as a film, a solid, or a sheet. The silicone resin reflective substrate can be easily formed as a wiring substrate, a packaging case or the like, and can be manufactured at low cost and a high rate of production.
