具体实施方式
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施方式。但是，本发明可以通过许多不同的形式来实现，并不限于下面所描述的实施方式。相反地，提供这些实施方式的目的是使对本发明的公开内容理解的更加透彻全面。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本发明。本文所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
本发明揭示一种光学装饰膜，其包括支撑层、光学层和装饰层。支撑层包括相对设置的第一侧面和第二侧面。光学层成型于第一侧面，光学层包括凸起和/或凹陷设置的复数微纳结构。装饰层设置于第二侧面并由支撑层所支撑。支撑层的第一侧面和第二侧面分别设置有光学层和装饰层，具有双重装饰效果，辨识度较高，且仅有一层支撑层，厚度较薄。
装饰层设置于第二侧面并由支撑层所支撑，光学层和装饰层均由支撑层来支撑，且光学层和装饰层的支撑层为同一层。支撑层具有一定的厚度和硬度，比如PET、玻璃等，以方便光学层和装饰层的成型，并起支撑作用。支撑层的两侧均设置结构，可最大限度的扩大装饰效果和减小光学装饰膜的整体厚度。
优选的，装饰层包括覆设于第二侧面的反射层和覆设于反射层上的着色层。光学层设置于支撑层的第一侧面，反射层和着色层设置于支撑层的第二侧面，工艺简单，装饰效果出色。相比于分别在支撑层上成型后再叠加减小了厚度。
优选的，装饰光学膜还包括覆设于光学层上用于保护微纳结构的保护层，保护层与微纳结构的折射率差大于等于0.01，从而保证了微纳结构的光学特性。
优选的，支撑层包括一层玻璃层、一层PET层、一层PC层或一层PMMA层。也即装饰光学膜的支撑层为单层结构，并在支撑层的两侧分别设置光学层和装饰层，从而即增加了装饰效果，又降低了装饰光学膜的整体厚度。
优选的，为保证观察效果，支撑层和光学层的透过率需大于等于10％，或者支撑层和装饰层的透过率大于等于10％。
优选的，装饰层包括纹理层、图文层或有色层中的一层或两层及以上的叠加层。或 者，装饰层包括有色纹理层或有色图文层的复合层。纹理层包括凸起和/或凹陷设置的复数纹理结构。叠加层是为两层或以上上下堆叠设置，比如，有色层和设置于有色层上的纹理层。复合层是为两层具有融合重叠部分，比如，形成纹理层的UV胶本身带有颜色。
优选的，微纳结构为直线柱面镜、曲线柱面镜、微透镜、菲涅尔透镜、CD纹、小短线、蛾眼结构、拉丝纹中的一种或几种，各微纳结构间隔或无间隔设置。纹理结构为直线柱面镜、曲线柱面镜、微透镜、菲涅尔透镜、CD纹、小短线、蛾眼结构、拉丝纹中的一种或几种，各纹理结构间隔或无间隔设置。微纳结构和纹理结构互不关联，且未相互干涉，也即各自独立设置。
优选的，微纳结构渐变设置，比如微纳结构为柱面镜，在一个排布方向上，柱面镜的宽度逐渐变小。
优选的，纹理结构渐变设置，比如纹理结构的截面为凹槽形式，在一个排布方向上行，凹槽的宽度之间变大。
优选的，图文层包括具有凹槽的UV胶和填充于凹槽内的填充物，该填充物形成图文层的图文。图文并不在微纳结构的焦距内，也即图文和微纳结构并不适配而成像。
优选的，有色层具有渐变色。比如有色层包括具有渐变凹槽的UV胶层和填充于凹槽内的有色材料，单位面积内的有色材料渐变设置，从而使有色层呈现渐变色。
优选的，支撑层为PET层，PET层的厚度大于装饰层的厚度。因为装饰层是直接成型在PET层上，或者装饰层在另一基材上成型后分离掉PET再粘结至PET层上的，故装饰层可以认为是无基材的，也即装饰层的整体厚度较PET层薄。本发明通过在PET层的另一侧成型装饰层，进一步增加了装饰效果，却仍能控制整个装饰光学膜的厚度，相比各带PET的装饰膜的简单叠加大大降低了厚度，符合市场发展需要。
优选的，光学装饰膜依次层叠为着色层、反射层、光学层、支撑层和装饰层。当然，其他实施例中，光学层和支撑层之间还可以包括有色层和/或图文层。
优选的,装饰层依次层叠有有色层和纹理层，或者装饰层依次层叠有图文层和纹理层，或者装饰层依次层叠有有色层和图文层，或者装饰层包括有色层、图文层和纹理层。
优选的，装饰层还包括将装饰层粘结至支撑层第二侧面的粘结层。
优选的，有色层为渐变色层。在一预定方向，颜色逐渐变浅或逐渐变深。比如，从上到下，颜色逐渐变浅；从两侧向内侧，颜色逐渐变浅。
优选的，纹理层的纹理结构渐变设置。在一预定方向，单位面积内占空比渐变设置。
优选的，装饰层还可至少包括两层及以上有色层。
优选的，装饰层还可至少包括两层及以上图文层。
优选的，装饰层还可至少包括两层及以上纹理层。
本发明还揭示一种消费电子产品盖板，其包括如上述所述的光学装饰膜。比如手机盖板，具有该光学装饰膜的手机盖板具有较好的装饰效果，辨识度也高，且虽有光学层和装饰层，但只有一层支撑层，不会增加手机盖板的厚度，满足市场轻薄发展趋势。
本发明还揭示一种光学装饰膜的制备方法，其包括如下步骤：
步骤1，支撑层的第一侧面涂布胶，优选为UV胶，然后在UV胶上成型复数微纳结构；
步骤2，装饰层通过其粘结层粘结至支撑层的第二侧面。
可先执行步骤1，再执行步骤2；或者，可先执行步骤2，再执行步骤1；或者步骤1和步骤2同时执行。
步骤1还包括在复数微纳结构上蒸镀反射层，在反射层上涂布着色层(优选为油墨打底层)。
本发明另一种光学装饰膜的制备方法，其包括如下步骤：
步骤1，支撑层的第一侧面涂布胶(优选为UV胶)，在胶上成型复数微纳结构；
步骤2，支撑层的第二侧面上成型装饰层。
可先执行步骤1，再执行步骤2；或者，可先执行步骤2，再执行步骤1；或者步骤1和步骤2同时执行。
步骤1还包括在复数微纳结构上蒸镀反射层，在反射层上涂布着色层(优选为油墨打底层)。
步骤2具体为，支撑层的第二侧面涂布胶(优选为UV胶)，在胶上成型复数纹理结构。或者，支撑层的第二侧面涂布胶(优选为UV胶)，在胶上成型复数凹槽并填充入材料后形成图文层。或者，支撑层的第二侧面涂布胶(优选为UV胶)，在胶上成型复数凹槽并填充如材料(有色材料)后形成有色层。
