Abstract
The utility model provides multi-layered gradient color-changing anti-counterfeiting carbon-free paper which comprises a base layer (1) as well as a dark color-changing layer (2), an isolation layer (3) and a light color-changing layer (4) arranged on the base layer (1), wherein an external protective layer (5) is arranged on the light color-changing layer (4), and the external protective layer (5) is a CB (Carbon Back) coating for carbon-free CB/CFB (Coated Front and Back) paper or a lightly coated filler protective layer; the base layer (1) is level thin carbon-free body paper or CF (Carbon Front) paper; both the light color-changing layer and the dark color-changing layer contain a color former and a color developing agent; chemical chromogenic reaction in color is caused by heat energy generated by scribing the light color-changing layer and the dark color-changing layer; lines in different colors are generated by quickly and slowly scribing the coating paper face by fingers, and the color-changing lines have a gradient color-changing characteristic. The multi-layered gradient color-changing anti-counterfeiting carbon-free paper provided by the utility model mainly has the beneficial effects that the anti-counterfeiting performance of carbon-free paper in high performance is achieved by adopting a simpler technical means, and has the advantages of low cost and excellent performance.
Description
Technical field
The utility model relates to a kind of false proof carbonless paper, is specifically related to the false proof carbonless paper of a kind of multilayer gradient color.
Background technology
No carbon paper, as the first-selection of multi-joint single vote card paper using, is widely used in the fields such as finance, the tax, customs, for taking precautions against false making, fakes, and need from paper production, give ticket basic anti-counterfeiting performance, to improve counterfeit difficulty.The double-colored false proof carbon-free CB/CFB paper of < < and production technology > > (application number is CN201110412627) thereof that our company has now worked out, in existing carbonless paper coating process of manufacture, use encapsulated technology to carry out emulsification parcel to the second developing dye, or by grinding technics, the second developing dye is carried out to further processing and make an addition to again in the CB coating of different colour developings, coat body paper or the CF paper back side, produce the carbon-free CB/CFB paper that carries double-colored function, stable performance, identify simple and easy, be subject to extensive favorable comment.Our company, in conjunction with Coating technology, wishes further to strengthen its performance in subsequent development.
Utility model content
For more outstanding security feature being provided to false proof carbonless paper, the utility model provides a kind of multilayer gradient color false proof carbonless paper, by finger, at the speed of coating paper, rule, produce the lines of different colours, this variable color lines have a kind of gradient color feature.
In order to realize above-mentioned utility model object, the technical solution adopted in the utility model is as follows:
The false proof carbonless paper of gradient color, is characterized in that comprising basic unit, and is successively set on dark photochromic layer, separation layer and light photochromic layer on basic unit.
Further, on described light photochromic layer, outer protection layer is set.
Further, described outer protection layer can be carbon-free CB/CFB paper CB coating, or the filler protective layer of dab.
Further, described basic unit is the smooth carbon-free body paper of thin page or CF paper.
The beneficial effects of the utility model are mainly to have realized the high performance anti-counterfeiting performance of carbonless paper by comparatively simple technological means, have advantages of performance brilliance with low cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation profile;
Wherein: 1 basic unit; 2 dark photochromic layers; 3 separation layers; 4 light photochromic layers; 5 outer protection layers.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
The false proof carbonless paper of a kind of multilayer gradient color that the utility model provides, comprises basic unit 1, and is successively set on dark photochromic layer 2, separation layer 3, light photochromic layer 4 on basic unit 1.
At this product, add man-hour, by 5 pairs of two-layer photochromic layer of coating outer protection layer, carry out outer protection.Outer protection layer 5 can be carbon-free CB/CFB paper CB coating, or the filler protective layer of dab.
Because the utility model is applied on carbonless paper, the basic unit 1 of paper can select the smooth carbon-free body paper of thin page or CF paper, and at the former paper of paper, carry out the processing of above-mentioned each coating, be coated with again CB paint coatings or protective coating layer for no carbon paper, finally complete the coating processing of no carbon paper CB, CFB, CF paper.
Principle of the present utility model is: light and dark photochromic layer all contains colour former and developer, the color of light color photochromic layer and dark photochromic layer is that the heat energy by producing after ruling causes that chemical colour reaction reaction occurs for it, therefore by the buffer action of separation layer, first the conduction of heat causes bleached bed color development, this is after friction is rule at a slow speed, and it is consistent only having bleached bed variable color; And after fast to coating paper line, the heat energy of friction is larger, have more that heat energy is outside guaranteeing bleached bed color development, some heat energy sees through separation layer and is transmitted to nexine, causes dark photochromic layer generation metachromasia.According to the number of heat energy, the degree of depth of photochromic layer generation variable color has different, and in conjunction with the actual color degree of depth of light photochromic layer and dark photochromic layer, from the top view of paper, has different composite coloured manifesting.It shows as: by finger nail or other hard things when this Paper Coating face line, slowly after line, light photochromic layer manifests color, display light lines, and light color and the equal variable color of dark photochromic layer after fast scribing, color is the tertiary colour of light color and dark strokes, observing the lines of different fast jogging speed line, is gradient color line lines.In addition, at different time, observe, some also can occur this gradient color changes, and such as As time goes on the tone of bleached bed can fade gradually, only retains the color of dark layer, or dark layer fades, and only retains the tone of bleached bed.This is second variable color feature of gradient color.
By to each layer of different setting, can reach different color combination, following table has provided some different materials combinations of each coating, and analyzes the characteristic performance in its anti-pseudoprocess:
The actual effect of above example is that example 1 is red, royal purple gradual change colo(u)r streak, is scribed ss slowly red lines, is scribed ss soon red and blue tertiary colour-purple; Example 2 is yellow, blood orange gradual change colo(u)r streak, is scribed ss slowly yellow line, is scribed ss soon the tertiary colour of Huang Yuhong-orange; Example 3 is yellow, bluish-green gradual change colo(u)r streak, is scribed ss slowly yellow line, is scribed ss soon tertiary colour-green of Huang Yulan.The present embodiment object is to make professional and technical personnel in the field to understand the technical solution of the utility model and to be implemented according to it; can not limit with it protection domain of this patent; all distortion of doing according to the utility model disclosure technology, all fall into protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims content.
