Abstract
The utility model provides special type counterfeit-proof stamp paper, which comprises a raw paper layer, a remoistening glue layer and a coating layer, wherein at least one kind of colorless fluorescent particles is evenly distributed on the raw paper layer. The defect that counterfeit-proof paper can not be coated or recoated can be solved. Meanwhile, colorless fluorescent particles are covered by paint and the appearance of the raw paper layer is the same with ordinary stamp paper. Thus, a printing effect can not be influenced. When printing requirements are met, an anti-counterfeiting function can be implemented simultaneously.
Description
Technical field
The utility model relates to a kind of stamp paper, is meant the false proof stamp paper of a kind of special type especially.
Background technology
The production of cheque paper has the history of decades, and former cheque paper is mainly used in printing of bank note, and purposes is more single, and the anti-counterfeiting technology development also relatively slowly.But along with progress of science and technology, and the continuous development of production technology, the industrial level of entire society is all improving constantly, various commodity emerge in an endless stream on the market, competition between the manufacturer of like product also is growing more intense, counterfeit and shoddy goods also day by day increase, according to the interrelated data introduction, China every year because of economic loss that fake and inferior commodities caused up to 2,000 hundred million yuans.This phenomenon has not only greatly been damaged enterprise, consumer, the possessory legitimate rights and interests of copyright, but also grievous injury reputation and the image of China in international economic activity, especially after China had added WTO, the work of hitting and eliminate fake products more seemed very important.
With regard to present industrial counterfeit prevention paper, generally be directly colored fiber to be added the effect that reaches false proof in the paper, just added red fiber as used coating Bai Kazhong of brand such as Hongta, A Shima, Yuxi, but the manufacture difficulty of this red fiber itself is little, false proof mode unification simultaneously, and from red fiber visual effect, the personator is very easy to imitate to the life out with printing technology.For this reason, someone adopts multi-color section fibre to replace original monochromatic fiber, disclose a kind of colorful false proof paper and cardboard as Chinese patent ZL03228499.3 (notification number CN2617813Y, date of declaration on May 26th, 2004), also existed multi-color section fibre to make shortcomings such as complicated, that border transition is unintelligible, input cost is high, feature is not clear.Simultaneously, all inevitably there is another shortcoming in the method for above-mentioned adding colored fiber, be exactly that these colored fibers must be on the surface of paper, above the colored fiber thicker cover layer can not be arranged in other words, if in order to reach good printing effect, must be coated with body paper, and coating weight is also higher relatively (often greater than 20g/m
2), like this, the colored fiber on the body paper influences the identification of anti-counterfeiting mark just inevitably by all or part of covering.This shows that this technology that adds multiple color fiber in body paper has limited the quality of raising, the especially coated paper of the quality of paper to a certain extent.
The utility model content
The purpose of this utility model is to provide a kind of printing effect that do not influence, the false proof stamp paper of a kind of special type that anti-counterfeiting performance is good.
The purpose of this utility model is achieved in that the false proof stamp paper of a kind of special type, comprises original paper layer, rewetting glue layer and coating layer, wherein: be evenly distributed with at least a colorless fluorescent particle at original paper layer.
Colorless fluorescent particle described in the utility model both can be evenly distributed in the original paper layer, also the colorless fluorescent uniform particles can be distributed in the surface (single or double) of original paper layer.
After the utility model adopts said structure, solved that cheque paper can not be coated with or the shortcoming of recoat cloth; Simultaneously, the colorless fluorescent particle is covered by coating, and outward appearance and regular stamp paper are just the same, can not influence printing effect, when can satisfying print request, can play anti-fake effect again.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is wherein a kind of structural representation of specific embodiment of the utility model;
Fig. 2 is the structural representation of the another kind of specific embodiment of the utility model.
The specific embodiment
As shown in Figure 1, the false proof stamp paper of special type of the present utility model comprises original paper layer 1, rewetting glue layer 2 and coating layer 3, is evenly distributed with colorless fluorescent particle 4 in original paper layer 1.The utility model is in the production process of body paper, earlier the paper grade (stock) fiber raw material is pulled an oar, is joined slurry, toning and then scattered in advance colorless fluorescent particle 4 is added in the paper stocks.Can require to select the kind of the colorless fluorescent particle 4 of addition and adding during concrete production according to difference, to reach different distribution densities and different antifalse effects.Original paper layer 1 through coating, press polish after, surfacing, smooth, higher glossiness arranged, surface strength height, absorbency are good, printed patterns is clear, fine and smooth, true to nature, stereovision is strong.Because colorless fluorescent particle 4 is colourless under sunshine, and is covered by the coating, and does not have other variegated in printed patterns, can not influence printing effect.Under the irradiation of uviol lamp, ultraviolet luminous energy penetrates coating, makes colorless fluorescent particle 4 send coloured fluorescence.And colorless fluorescent particle 4 covers through coating, and sun-proof property is good, the fluorescence intensity decay is little, long shelf-life, is difficult for advantages such as counterfeit.
The fluorescence intensity that is ejected under ultraviolet irradiation because of colorless fluorescent particle 4 in the utility model is limited, when the powder amount is higher on the coating layer 3, the anti-counterfeiting characteristic that is showed is not clearly just, in this case, can make the surface (comprise single or double) of colorless fluorescent particle 4 attached to original paper layer 1 by surface spraying or top sizing, its structure is consulted shown in Fig. 2.
Claims (3)
1. the false proof stamp paper of special type comprises original paper layer (1), rewetting glue layer (2) and coating layer (3), it is characterized in that: be evenly distributed with at least a colorless fluorescent particle (4) at original paper layer (1).
2. the false proof stamp paper of special type according to claim 1 is characterized in that: described colorless fluorescent particle (4) is evenly distributed in the original paper layer (1).
3. the false proof stamp paper of special type according to claim 1 is characterized in that: described colorless fluorescent particle (4) is evenly distributed on the surface of original paper layer (1).
