In order to study the performance of the colored coated glass of the present invention, the coated glass of the examples and comparative examples was tested, and the test results are shown in tables 1 and 2.
TABLE 1 film layer structure and thickness of each example and comparative example
TABLE 2 color data as a function of angle for coated glasses of each example and comparative example
As can be seen from tables 1 and 2, the glare coated glass of examples 1 to 3 of the present invention has high reflectivity and variable color with the change of angle. And a variety of different color changes may occur as the thickness of the various film layers change.
As can be seen from comparative example 1, when the number of the film layers of the coated glass is small, the coated glass has low reflectivity and cannot meet the requirement of multi-color discoloration, and with the change of angles, only three colors of purplish red, dark gray and blue-green can appear, and the discoloration range is small.
It can be seen from comparative example 2 that, although the film structure of comparative example 2 is the same as that of the example, when the thickness of the first inner low refractive index SiO2 film layer and the thickness of the second inner high refractive index Nb2O5 film layer in comparative example 2 are greater than the corresponding film thicknesses in the example, the coated glass can achieve the effect of color change, but the color change range is narrow, and the change of multiple colors cannot occur.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
