Description

视觉立体漂浮图像的薄膜及其制备方法 FILM AND METHOD FOR visual stereo image floating

技术领域 FIELD

[0001] 本发明涉及安全防伪领域以及产品包装领域,具体涉及一种动态、立体的薄膜,既可以用于现金、有价证券、证卡、护照等的防伪认证,也可用于各种商品的外部包装,以其特殊的视觉效果增强商品对消费者的吸引力。 [0001] The present invention relates to the field of security and security product packaging, and in particular relates to a dynamic, three-dimensional film, may be used for cash, securities, cards, passports and other security authentication, also be used for various commodities external packaging, with its special visual effects to enhance product appeal to consumers.

背景技术 Background technique

[0002] 商品包装的原始作用是保护商品不受损伤。 Original role [0002] packaging is to protect goods from damage. 随着生活水平的不断提高,产品包装除了最基本的保护作用之外,还致力于对商品进行美化和宣传,以提高产品在市场上的竞争力和档次。 With the continuous improvement of living standards, product packaging, in addition to the protective effect of the most basic, it is also committed to the beautification of commodities and publicity, in order to improve product competitiveness in the market and grade. 故各式各样的平面装饰图案出现在了产品包装上,然而随着印刷技术的发展和普及,这些简单的商品外包装可以被轻松的复制,假冒商品越来越多,对厂商和消费者都造成巨大的损失。 Therefore, a variety of decorative patterns plane appeared on the product packaging, however, with the development and popularization of printing technology, these simple product packaging can be more and more easy to copy, counterfeit goods for manufacturers and consumers They have caused huge losses. 因此社会急需一种既美观又能起到防伪鉴别作用,同时又不容易被复制的全新的产品包装技术。 So need for a social security identification not only beautiful but also play a role, but not easy to be copied completely new packaging technology.

[0003] 激光全息包装防伪技术曾经以其绚丽的色彩、较高的制作技术门槛,迅速成为商品包装的新宠,并迅速扩散。 [0003] laser holographic anti-counterfeiting packaging technology with its once brilliant colors, high production technology threshold, and quickly became the new darling of packaging, and spread rapidly. 但时至今日,造假者已从各个方面攻破了激光全息防伪技术,使其几乎完全失去了防伪能力。 But now, counterfeiters break from all aspects of laser holographic anti-counterfeiting technology, making it almost completely lost its security capabilities.

[0004] Kaule等人在美国专利4892336中提出了一种安全线制作技术,也是目前流行的三维立体画制作技术的基础,它通过在膜体一侧的柱面透镜结构与另一侧特定印刷图案相结合产生逼真绚丽的三维图像。 [0004] Kaule et al proposed a safety wire fabrication techniques in U.S. Patent No. 4,892,336, the base is currently popular three-dimensional picture making technology, by which the particular print film body side structure of a cylindrical lens with the other side pattern brilliant combination produce realistic three-dimensional image. Drinkwater等人在美国专利5712731中提出一种利用球面微透镜阵列与微图文阵列相组合的安全装置,每一微透镜的孔径为50到250微米且优选的焦距为200微米,以上两种技术产品的机构比较厚重,无法用于商品的安全防伪和包装。 Drinkwater et al security device utilizing a spherical microlens array and the array of micro graphics combined in U.S. Patent No. 5,712,731, the aperture of each microlens 50 to 250 microns and preferably a focal length of 200 microns, or two or more techniques institutional products is relatively heavy, can not be used for security and anti-counterfeiting packaging goods.

[0005] RASteenblik在美国专利US2005180020A1中将上述专利的技术缺点进行了改进,将微透镜孔径减小到50微米一下,结构厚度也控制住50微米一下。 [0005] RASteenblik technical disadvantages in U.S. Patent No. US2005180020A1 in the above patents is improved, the microlens aperture is reduced to about 50 microns, but also control the thickness of the structure about 50 microns. 这样虽然克服了厚度问题,但随着透镜孔径的减小,其加工制作工艺难度也大幅增加。 While this overcomes the problem of thickness, but with the lens aperture is reduced, the difficulty of its manufacture technology has increased significantly. 同时受限与当今的印刷技术,如此微小的微缩图文只能通过紫外模压,然后用纳米染料填充的方法,工艺繁琐复杂,成本高且成品率低。 While limited to today's printing technology, so small miniature graphic only by UV embossing, nano-dye and a method of filling, the process cumbersome and complex, high cost and low yield.
