Embodiment Construction
[0008] The present invention consists of a first PET transparent film 1, a second PET transparent film 2, an anti-peeping layer 3, a rhombus texture 4, an anti-scratch layer 5 and an adhesive layer 6. First, the first PET transparent film 1 is coated with a doctor blade. After coating the anti-scratch layer 5, use a gravure roller to coat the diamond-shaped texture 4 on the reverse side of the first PET transparent film, and cure the coated diamond-shaped texture 4 by UV light irradiation, and wait for the diamond-shaped texture 4 to cure Finally, the anti-peep layer 3 is made by coating the curing agent with ultraviolet radiation for the second time on the rhombic pattern 4. After the above steps are completed, the anti-peep layer 3 is bonded to the second PET transparent film 2 with acrylic glue Finally, the silica gel is coated on the other side of the second PET transparent film 2 by means of doctor blade coating, so as to form an automatic adsorption, ultra-thin, anti-peep...
