example 1
[0253] In this example, the optical properties of a prior art crystal cut, such as the brilliant cut shown in FIG. 1 , are analyzed.
[0254] Figure 8A The fire color map of the crystal is shown, ie the reflection from the crystal under point illumination perpendicular to the table top, as observed on a screen parallel to the table top of the crystal at a distance of 50 cm from the stone. Figure 8B is like Figure 8A Brightness map of the cross-section of the fire color map shown above. Figure 8B The data on is obtained by following: along Figure 8A The cross-section shown above takes the combined value (on a gray scale from 0 to 255 arbitrary units) from the RGB camera sensor (y-axis) and maps it to the lateral position along the cross-section by the number of pixels on the sensor (x axis) to draw. Figure 8C An image of cut crystal is shown, revealing a strong contrast between light and dark areas. Figure 8C The data shown in were obtained using the components desc...

[0257] In this example, the optical properties of various embodiments of the decorative structure of the invention were investigated.
[0258] Figure 9A and 9B Light reflection simulations of exemplary decorative structures according to the present invention are shown when these structures are exposed to light perpendicular to the first planar major surface of the support. Figure 9A shows the use of Figure 2A The angle of light reflection for the illustrated embodiment; Figure 9B shows the use of Figure 2B The angle of light reflection for the illustrated embodiment. Shaded areas represent angles to the normal (vertical line, which is the direction of incidence of light) at which light is expected to be reflected by the at least partially reflective layer of the decorative structure; horizontal lines correspond to the plane of the at least partially reflective layer; and, The shaded area below the horizontal line corresponds to the reflection through the edge of the ...

[0267] In this example, the inventors studied the optical characteristics of various ultraviolet curable resins according to the present invention and comparative examples. The refractive indices of the various cured compositions were obtained by variable angle spectroscopic ellipsometry by using a xenon lamp between 300 nm and 1700 nm and measuring at angles of incidence of 55°, 60°, 65°, 70° and 75°. Abbe's number was calculated from this data as described above.
[0268] Figure 16 Refractive index (y-axis) as a function of wavelength (x-axis) for various cured resins obtained from curable resin compositions according to the present invention (Samples 1-3) and comparative examples (Samples 4-8) are shown graphically relation.
[0269] The samples are as follows: Sample 1: Allnex RX15331 (a nanocomposite resin containing zirconia)+TPO-L; Sample 2: M1142+TPO-L; Sample 3: M1142+SR348+TPO-L (65.3% of M1142, 32.7% SR348c, 2% TPO-L by weight); Sample 4: SR348+TPO-L; Sample 5: ...
