13 are correspondingly arranged.Ink layer 60 and film plating layer 50 are opaque, thus in 12 side of second surface towards first surface 11
When direction is observed, the scene of 11 side of first surface of substrate 10 blocked by ink layer 60 and film plating layer 50 can't see.Ink
Layer 60 is also possible to single-layer or multi-layer.In present embodiment, the first texture layer 40, film plating layer 50 and ink layer 60 are annular
Structure.
Film plating layer 50 and ink layer 60 are set on first texture layer 40, since film plating layer 50 and ink layer 60 are opaque,
Light is blocked after passing through the first texture layer 40 by film plating layer 50 and ink layer 60, but due to 40 light transmission of the first texture layer, in base
The 12 side user of second surface of plate 10 still can be observed what the first texture layer 40, film plating layer 50 and ink layer 60 were showed
Pattern, thus the user for being located at 12 side of second surface is able to observe that the colorful that film plating layer 50 and ink layer 60 show is imitated
Fruit；And it is blocked in the light that the pattern of the side opposite with second surface 12 of cover board 100 issues by ink layer 60 and film plating layer 50
Afterwards, it does not pass through the first texture layer 40 and is seen by the user positioned at 12 side of second surface, thus be located at second surface 12 1
The user of side not can be appreciated that the pattern in the side opposite with second surface 12 of cover board 100.
The light for being radiated at film plating layer 50 and ink layer 60 reflects by film plating layer 50 and ink layer 60 and is transferred to first
When texture layer 40, which interferes on the surface of the first texture layer 40, which is transferred to 13 Shi of the second texture layer
Two texture layers, 13 surface occurs second and interferes, therefore the user for being located at 12 side of second surface can penetrate the second texture layer 13
And first texture layer 40 see the pattern of more colorful that film plating layer 50 and ink layer 60 are showed.
Embodiment of the present invention cover board 100 forms the second texture layer 13 by the second surface 12 in substrate 10, and the
The first texture layer 40 is arranged in one surface 11, interferes light when passing through the first texture layer 40 and/or the second texture layer 13, from
And allow users to see the visual effect of colorful, improve the usage experience of user.
