中文摘要:
      基于微透镜阵列的防伪膜技术便于观察和易于识别的特点,采用高感光度的AZ 1500和较高解像度的AZ MIR-703正性光刻胶以及SU-8负性光刻胶对微透镜阵列防伪膜进行制备,光刻胶热熔法被用来制作微透镜阵列,PDMS被用来制作微透镜阵列的倒模,将SU-8和PDMS倒模配合使用制作最终的微透镜阵列,利用AZ 1500光刻胶制备微缩文字阵列,从而得到具有体视效果的微透镜阵列防伪膜。实验表征和分析表明,这种方法制备的微透镜阵列防伪膜效果明显,均匀性好。该方法与其他方法相比,工艺简单,对材料和设备的要求不高,工艺参数稳定易于控制,是一种微透镜阵列防伪膜制备的简便新方法。
英文摘要:
      The microlens array anti-counterfeiting film technology is a new anti-counterfeiting technology, which is easy to observe and easy to identify, especially in the environment of insufficient light. A high sensitivity positive photoresist AZ 1500, a high-resolution positive photoresist AZ MIR-703 and a negative SU-8 photoresist were used to produce a microlens array anti-counterfeiting film. Photoresist melting was used to fabricate the microlens array, PDMS was used to fabricate the reverse mold of the microlens array, SU-8 and PDMS reverse mold were used together to make the final microlens array, and the photoresist AZ 1500 was used to fabricate the microtext array. Subsequently, a kind of microlens array anti-counterfeiting film with a stereoscopic effect was obtained. The experimental characterization and analysis show that the microlens array anti-counterfeiting film prepared by the method has obvious effect and good uniformity. Compared with other methods, the method has the advantages of simple process, low requirement for material and equipment, stable process parameter and easy control. It is a simple and novel method.
