[0011] Furthermore, the reflectivity of the glass plate to light incident at an incident angle of 8° is less than or equal to 7.6%.

[0012] Furthermore, the transmittance of the glass plate to light incident at an incident angle of 8° is greater than or equal to 80.7%.

[0013] Furthermore, the reflectivity of light incident at an incident angle of 8° is less than or equal to 42.6%.

[0014] Furthermore, the transmittance of light incident at an incident angle of 8° is greater than or equal to 49.9%.

[0015] Compared with the prior art, the beneficial technical effects of the utility model are:

[0016] The utility model has color after reflecting light, has certain decorative effect, and does not need to stick additional color film. In addition, the utility model has high reflectivity and low transmittance, has privacy and UV protection functions, avoids direct sunlight burning the skin, and effectively solves the problem of poor privacy and lack of UV protection of existing automobile side windshields. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0018] A kind of automobile side windshield coated glass, such as Figure 1 As shown, it includes a glass plate 1 and a coating layer, the glass plate includes a first surface 11 and a second surface 12 opposite to each other, the coating layer is arranged on the first surface 11, and the coating layer includes a first film layer 2, a second film layer 3, a third film layer 4 and a fourth film layer 5 stacked in sequence from the first surface 11 to the outside.

[0019] The materials of the first film layer 2 and the third film layer 4 are both Nb2O5, and the materials of the second film layer 3 and the fourth film layer 5 are both SiO2. This embodiment reflects blue-green under light, has a certain decorative effect, and no additional color film is required.
