Embodiment
[0032] A method for UV-cured microstructure particles, such as figure 1 As shown, the method includes the following steps:
[0033] (1) coating a layer of peeling adhesive film 3 on the base film 4;
[0034] (2) coating the UV-curable coating layer 2 on the stripping adhesive film 3;
[0035] (3) placing a template 1 with a microstructure pattern 6 on the UV-curable coating layer 2;
[0036] (4) UV light is irradiated by the UV light source 5 on the underside of the base film 4, so that the UV-curable coating layer 2 is cured and broken into the same microstructure particles as the microstructure pattern 6 on the template 1, and the microstructure particles are peeled off. The adhesive layer is pasted on the base film 4;
[0037] (5) Peel off the microstructure particles from the base film 4 .
[0038] Wherein, the base film 4 is a plastic substrate with a smooth and even surface that can transmit ultraviolet light. The peeling adhesive film 3 is a thin film that can tran...
