Embodiment approach 1
[0077] Antistatic agent: AS-5 from Guangzhou Zhenke Technology Co., Ltd.;
[0078] Substrate: Toray's 50μm and 100μm PET substrates;
[0079] Glitter powder: golden glitter powder from Shantou Guansheng Plastic Co., Ltd.;
[0080] 5% by weight of antistatic agent AS-5 was added to the UV-type acrylic resin glue, and it was coated on the substrate A 22 by a micro-gravure roller. First bake at 80 for 60s, and then completely cure with UV lamp, the energy of UV lamp is 400mJ / cm2. Wherein the thickness of the UV hardening layer 21 is 5±1 μm, the thickness of the A substrate 22 is 100 μm, the haze is 0, and the light transmittance is 94%;
[0081] Add 1‰ golden glitter powder to the silicone pressure-sensitive adhesive, filter it through a 20μm filter element and a 5μm filter element, and then apply the glue on the other side of the A substrate 22 with a scraper, at 200°C Dry for 2 minutes, and cover with a release film as the release layer 30 to obtain a 2-layer composite film....
Embodiment approach 2
[0085] Antistatic agent: AC-1203 from Juli Chemical;
[0086] Substrate: Toray's 50μm and 100μm PET substrates;
[0087] Flash powder: pearlescent flash powder from Shantou Guansheng Plastic Co., Ltd.;
[0088] Apply the UV-type acrylic resin glue on the substrate A 22 through a micro gravure roller, bake it at 100°C for 45s, and then completely cure it with a UV lamp whose energy is 400mJ / cm2. Wherein the thickness of the UV hardening layer 21 is 7±1 μm, the thickness of the A substrate 22 is 100 μm, the haze is 0, and the light transmittance is 94%;
[0089] Add 5 / 10,000 pearlescent flash powder and 1% antistatic agent to the silicone pressure-sensitive adhesive, filter through two 5μm filter elements, and then apply the glue to the other side of the substrate A 22 with a scraper One side was dried at 200° C. for 2 minutes, and covered with a release film as the release layer 30 to obtain a two-layer composite film. Wherein the thickness of the adhesive layer 23 of A is 3...

[0093] Antistatic agent: AC-1203 from Juli Chemical;
[0094] Substrate: Toray's 50μm and 100μm PET substrates;
[0095] Flash powder: purple and silver flash powder from Shantou Guansheng Plastic Co., Ltd.;
[0096] 2% by weight of antistatic agent AC-1203 was added to the UV-type acrylic resin glue, and it was coated on the substrate A 22 by an anilox roller. First bake at 100°C for 45s, and then completely cure with UV lamp, the energy of UV lamp is 400mJ / cm2. Wherein the thickness of the UV curable layer 21 is 8±1 μm, the thickness of the A substrate 22 is 100 μm, the haze is 0, and the light transmittance is 94%;
[0097]Add 3 / 10000 weight ratio of silver, purple flash powder and 3% antistatic agent to the silicone pressure-sensitive adhesive, filter through a 20μm filter element and a 3μm filter element, and then apply the glue with a scraper On the other side of the substrate A 22, dry at 200° C. for 2 minutes, and cover with a release film as the release layer 30 to...
