Abstract

The utility model relates to anti-counterfeit paper with hidden variable patterns. The anti-counterfeit paper comprises a paper layer and is characterized in that a colored hidden variable pattern layer is arranged on the paper layer; and a non-carbon copy paper CB (coated back) coating layer is arranged on the surface of the colored hidden variable pattern layer. The anti-counterfeit paper has the following advantages: the colored hidden variable patterns are formed by coating a layer of anti-counterfeit coating with a hidden variation function by a special coating process; and the anti-counterfeit patterns are hard to copy by a printing method.

Description

The latent pattern anti-fake paper that becomes

Technical field

The utility model relates to false proof field, relates in particular to a kind of latent change pattern anti-fake paper.

Background technology

Current because the imitated raising of falsely using correlation technique; Paper such as bill, marketable securities, certificate certificate, sign sign require also increasingly high with the anti-counterfeiting technology of product; In order to satisfy this false proof requirement; Before paper is with the product printing, increase the coating of a kind of latent change pattern anti-fake of coating, form a kind of latent change pattern and reach the purpose that improves the product false proof function.

Summary of the invention

For addressing the above problem, the utility model provides a kind of special anti-fraud functional coloured latent change cheque paper that has.

For achieving the above object; The technical scheme that the utility model adopts is: a kind of latent change pattern anti-fake paper; Comprise paper layer, it is characterized in that: said paper layer is provided with coloured latent change patterned layer, and said coloured latent change patterned layer surface is provided with NCR CB dope layer.

First preferred version of the utility model is that the pattern of said coloured latent change patterned layer is at least a in literal, the pattern.

Second preferred version of the utility model does, the color of the pattern of said coloured latent change patterned layer is at least a kind of in any stack look of red, green, blue or redgreenblue.

The 3rd preferred version of the utility model is that the pattern discoloring temperature scope of said coloured latent change patterned layer is-15～70 ℃.

The 4th preferred version of the utility model does, the pattern of said coloured latent change patterned layer is latent to be become color and be red, blue, green, a kind of in deceiving.

The technical advantage of the utility model is: on body paper, have the latent anti-counterfeit paint that becomes function through special coating process coating one deck, and form coloured latent change pattern, this security pattern is difficult to printing process imitated.After particularly being coated with the carbonless copying functional paint on this basis; Formed coloured latent change pattern anti-fake NCR; Do not influence carbonless copying; The latent change can demonstrate latent change color after pattern is in manifolding, and the pattern of printing then must influence manifolding can not present the latent color that becomes yet, and latent change pattern anti-fake paper antiforge function is stronger.

Below in conjunction with specific embodiment the utility model is further specified.

Description of drawings

Fig. 1 is the latent pattern anti-fake paper structure sketch map that becomes.

The specific embodiment

With reference to figure 1, the latent pattern anti-fake paper that becomes is that coating one deck can produce the latent coating that becomes pattern on common former paper layer, and Fig. 1 intermediate cam shape presentation layer forms a kind of coloured latent change security pattern layer on paper, has so just improved anti-counterfeiting power.The pattern form of coloured latent change patterned layer can be lines, literal, figure emblem etc.; The color of coloured pattern has multiple color such as red, yellow, blue, black optional; The temperature range of pattern be-15～70 ℃ optional; The latent color that becomes has red, blue, green, black optional.

Be coated with NCR CB dope layer on this basis, the circular zone that indicates among Fig. 1, formed coloured latent change pattern anti-fake NCR does not influence carbonless copying, and latent the change can demonstrate the latent color that becomes after pattern is in manifolding.

Claims

1. the latent pattern anti-fake paper that becomes comprises paper layer, and it is characterized in that: said paper layer is provided with coloured latent change patterned layer, and said coloured latent change patterned layer surface is provided with NCR CB dope layer.

2. latent change pattern anti-fake paper according to claim 1, it is characterized in that: the pattern of said coloured latent change patterned layer is at least a in literal, the pattern.

3. latent change pattern anti-fake paper according to claim 1 is characterized in that: the color of the pattern of said coloured latent change patterned layer is at least a kind of in any stack look of red, green, blue or redgreenblue.

4. latent change pattern anti-fake paper according to claim 1 is characterized in that: the pattern discoloring temperature scope of said coloured latent change patterned layer is-15～70 ℃.

5. latent change pattern anti-fake paper according to claim 1 is characterized in that: the pattern of said coloured latent change patterned layer is latent to be become color and is red, blue, green, a kind of in deceiving.
