Description

A kind of anti-fake material
Technical field:
The present invention relates to a kind of anti-fraud functional material that has, particularly relate to a kind of anti-fake material with concaveconvex structure.
Background technology:
Have concaveconvex structure and utilize visual angle change to realize the pattern conversion to realize anti-fraud functional prior art, conclusion gets up to have following several mode:
1, stereosopic printing: be characterized on special printed patterns covering and have convex lens function, the transparent organic material of raised line shape.When changing viewing angle, the light refraction angle changes, thereby sees different respectively corresponding patterns, and realizes change in pattern.The limitation of this technology is that the variation that will realize this refraction angle must need certain thickness.Convex lens layer current material can not be lower than 0.5 millimeter, and can only realize that unidirectional angle changes, and involves great expense.Its limitation is very strong, only can do ornament usefulness at present, and can't enter that to need paper and plastic sheeting be packaging material and have in the material of aluminium coated.
2, inteferometer coating: be characterized in that mould goes out a lot of concave and convex stripes on transparent organic film, when changing viewing angle, cause the variation of concave and convex stripe optical interference effect owing to the angle variation of incident ray.Because inteferometer coating is made simple, and the visual angle characteristic of conversion is very limited, so antifalse effect is relatively poor.
3, the embossing tooth of band micro-structural: U.S. Patent Application Publication US2004151796A1 (on August 5th, 2004 is open) has put down in writing on flat material and has generated the embossing mark with knurling rolls, these embossing marks can be with observer's viewing angle, light source type and position change, these variable embossing marks as anti-fake mark are to realize by means of the embossing tooth that has micro-structural on the knurling rolls, promptly owing to have different micro-structurals on the different embossing teeth, when the embossing tooth formed the corresponding embossing mark of profile of tooth with the embossing tooth on flat material, micro-structural also had been pressed in the diverse location in the embossing mark simultaneously.When observing the embossing mark, owing to the interference effect of micro-structural to light, the embossing mark of being seen just changes with viewing angle, light source type and position.The essence of its variation also is the interference effect of having utilized light.Because the setting at random of micro-structural and the randomness of interference effect on the embossing tooth, therefore we can only see that the embossing mark is the embossing mark that changes, but, it changes and is irregular, be at random, unordered and mixed and disorderly, also can't form the effect of sudden change, concerning false proof application person, its identification false proof unique feature be exactly the embossing mark with viewing angle, light source type and change in location, therefore, the recognition feature of anti-fake mark is not obvious.
Also have some to utilize concaveconvex structure to carry out false proof security document in addition, realize antiforge function by concaveconvex structure specific physical effect to light under micro-structural mostly.Difficulty is very big even the technology that has is used to make the security document process, false proof threshold height, but the same not quite or not problem intuitively of identification distinctiveness that exists, being difficult to be applied in becomes the good line anti-counterfeiting technology that can significantly catch sight line and accurately discern in paper and the plastic sheeting.
