Abstract

The invention provides an anti-counterfeit white cardboard. The anti-counterfeit white cardboard comprises a base paper layer, a core paper layer, a surface paper layer and a first coating layer which are sequentially overlapped, wherein a first starch layer is arranged between the base paper layer and the core paper layer, and a second starch layer is arranged between the core paper layer and the surface paper layer; at least one in the first starch layer, the second starch layer and the first coating layer contains infrared anti-counterfeit substance. Compared with the prior art, the anti-counterfeit white cardboard contains the infrared anti-counterfeit substance in the starch layers or the coating layer, and the infrared anti-counterfeit substance is white or colorless under the sunlight and takes on specific color under the infrared ray, so that the appearance and the printing performance of the white cardboard are not influenced while the anti-counterfeit function of the white cardboard is reached, and the anti-counterfeit white cardboard has high secrecy; furthermore, the infrared anti-counterfeit substance is added into the starch layers or the coating layer, so that other performances of the white cardboard are prevented from being influenced; the bonding strength between the base paper layer and core paper layer as well as between the core paper layer and the surface paper layer can be improved by the starch layers.

Description

—种防伪白卡纸 - kind of security paperboard

技术领域 FIELD

[0001] 本发明属于防伪技术领域,尤其涉及一种防伪白卡纸。 [0001] The present invention belongs to the technical field of security, in particular, it relates to a security white cardboard.

背景技术 Background technique

[0002] 随着经济的发展,伪造(假冒)与防伪之间的矛盾越来越尖锐。 [0002] With economic development, forged between the (fake) anti-counterfeiting and contradictions more acute. 一方面,由于假冒或伪造商品可带来巨额利润,使伪造者铤而走险深入地研究破密和伪造方法;另一方面,随着各种新技术的涌现,尤其是计算机图形处理技术、彩色复印、高精度扫描、高分辨打印、数字化印刷技术的迅速发展、使原有的防伪措施很容易失落。 On the one hand, due to the fake or counterfeit goods can bring huge profits, so that counterfeiters desperate depth study of the descrambler and counterfeiting methods; on the other hand, with the emergence of new technologies, especially computer graphics technology, color copying, precision scanning, high-resolution printing, the rapid development of digital printing technology, so that the original anti-counterfeiting measures easily lost. 因此,研究和开发各种新型、高效的防伪技术,是社会、经济发展的迫切需要。 Therefore, the research and development of new, effective anti-counterfeiting technology is an urgent need for social and economic development.

[0003] 就现有防伪技术而言,通常由物理(光电)、化学、物理化学、生物等几种方法,不同的防伪技术或方法由不同的防伪效果,一般来说,在现有商品防伪中,采用何种防伪技术或方法要视具体情况尤其是根据物品的价值和用途而定。 [0003] For the prior art in terms of security, a method usually consists of several physical (optical), chemical, physical, chemical, biological, or anti-counterfeiting technology different methods by different anti-counterfeit effect, in general, in the conventional commodity security in which anti-counterfeiting techniques or methods employed depends on the specific circumstances and the particular use based on the value of the set item. 由于纸张用途广泛、使用方便、符合环保,而且具有技术、材料双重防伪等特定,因此,防伪纸张及其防伪技术一直以来受到人们的青睐和应用。 Due to the widespread use of paper, easy to use, environmentally friendly, but also technical, material and other specific double security, therefore, security paper and anti-counterfeiting technology has been favored by people and applications.

[0004]目前,一般的防伪纸采用水印、安全线、荧光纤维等技术。 [0004] Currently, the general use of security paper watermark, security thread, fluorescent fibers and other technologies. 水印防伪,需要加水印辊或者其他图案来制作水印,这种防伪技术需要对设备进行改造,投入设备大;安全线防伪是在造纸成型时喷入金属丝,这种方法的防伪效果好,但同样具有设备投资大的缺点,且操作复杂;荧光纤维技术是在纸中添加荧光纤维的防伪技术,这样的纸张在紫外光下会发出各种颜色的荧光,但由于荧光纤维比较脆,且在生产使用时分布不均匀,操作不方便,容易在纸上造成其他一些纸病,不能在高档印刷时会用,影响了该防伪技术的使用防伪。 Watermarks, or other need to add a watermark pattern roll watermarking, security techniques require that modify the equipment, large equipment investment; anti-counterfeit security threads in paper making is injected into the forming wire, forgery prevention effect of this method is good, but the same disadvantage of having a large investment in equipment and complex operation; fluorescent fiber technology is to add anti-counterfeiting technology fluorescent fibers in the paper, such paper will fluoresce under ultraviolet light in various colors, but the relatively brittle fluorescent fibers, and in when using non-uniform distribution of the production, inconvenient operation, the paper is likely to cause disease in a number of other paper can not be used when high-end printing, anti-counterfeiting affecting the use of the anti-counterfeiting technology.

[0005] 现有防伪涂布白卡纸是在白卡背面涂布层中添加有色颜料,形成防伪颜色涂布层,但这种防伪技术因背面有颜色,防伪的隐蔽性不强;还有是在白卡纸制备的表面施胶过程中加入普通荧光增白剂,在紫外灯下呈蓝色用以辨别,但荧光增白剂普遍用于涂布白卡纸的生产中,使其防伪性能不高。 [0005] Existing security coated paperboard white card is added in the back surface coating layer colored pigments, the color coating layer is formed security, anti-counterfeiting technology but this color due to the back, hidden security is not strong; and It is added to the surface sizing process of preparing white cardboard ordinary optical brighteners, blue under UV light for discrimination, but commonly used fluorescent whitening agent in the production of coated paperboard, it forgery performance is not high.
