Abstract

本发明公开了一种裸眼3D防伪材料，包括基材，基材两侧涂布UV光油，UV光油经过压印形成上下两层微透镜阵列，上下微透镜阵列交错。顶层纹路和底层纹路错位产生的放大效果随着光线射入角度的不同产生不同的方法效果，若底部纹路为0.01mm，在转动角度达到30°的时候，纹路可放大至5mm，放大效果显著，并且图案更加立体，实现裸眼3D效果。

Description

裸眼3D防伪材料
技术领域
本发明涉及一种裸眼3D防伪材料。
背景技术
为了鉴别商品的真伪，经常会在商品上用上防伪鉴别材料，微透镜材料被广泛使用，现有的微透镜材料多为在基材上铺设一层凸点排布的微透镜阵列，通过微透镜阵列将基材上的图案放大，实现真伪的鉴别，但是一层微透镜所能放大的效果比较小。
发明内容
本发明涉及一种裸眼3D防伪材料，可以将放大效果扩大。
为实现这一目的，本发明所采用的方法是：一种裸眼3D防伪材料，包括基材，所述基材两侧分别涂布顶层UV光油和底层UV光油，顶层UV光油和底层UV光油分别通过压印形成顶层纹路和底层纹路，所述顶层纹路和底层纹路均为球形凸点形成的微透镜阵列，所述顶层纹路和底层纹路的球形凸点位置相互交错。
所述顶层纹路和底层纹路直径相同或顶层纹路直径大于底层纹路直径。
一种制作裸眼3D防伪材料的方法，步骤如下：
（1）将基材上层涂布顶层UV光油，顶层UV光油通过压印形成顶层纹路，将基材下层涂布底层UV光油，底层UV光油通过压印形成底层纹路，底层纹路与顶层纹路相互交错；
（2）用UV灯照射使UV光油固化。
其有益效果是：顶层纹路和底层纹路错位产生的放大效果随着光线射入角度的不同产生不同的方法效果，若底部纹路为0.01mm，在转动角度达到30°的时候，纹路可放大至5mm，放大效果显著，并且图案更加立体，实现裸眼3D效果。

（2）用UV灯照射使UV光油固化。
如图2所示，顶层纹路和底层纹路错位产生的放大效果随着光线射入角度的不同产生不同的方法效果，若底部纹路为0.01mm，在转动角度达到30°的时候，纹路可放大至5mm，放大效果显著，并且图案更加立体，实现裸眼3D效果。
本发明并不局限于前述的具体实施方式。本发明扩展到任何在本说明书中披露的新特征或任何新的组合，以及披露的任一新的方法或过程的步骤或任何新的组合。
