Abstract
The present invention belongs to pressure-sensitive carbon paper. Colorless coating or printing ink containing organic ultraviolet fluorescent complexes are coated or printed on the back surfaces of the upper part and the middle part of the pressure-sensitive carbon paper, so that the duplication writing generated by hand writing or typewriting with the pressure-sensitive carbon paper is cryptomorphic and shows a fluorescent color only under the irradiation of ultraviolet light within a specific wavelength range. Consequently, the pressure-sensitive carbon paper can effectively prevent the fake signature and the alteration of written evidence. The pressure-sensitive carbon paper has advantages of simple and convenient use, beautiful paper surface and multiple duplications, and is novel carbon paper used for faking prevention for various fields of commerce, banking and finance.
Description
The invention belongs to the carbon paper that utilizes the feasible color of covering of pressure to show, promptly be commonly called as pressure-sensitive carbon paper, and preparation method thereof.
JP05-214278 has introduced a kind of pressure-sensitive carbon paper that scribbles common coloured organic fluorescent dye, and the duplication handwriting that this class carbon paper produces is all shown one's color, and the writing ratio of showing one's color is easier to by counterfeit or altered.JP59-98892 and JP04-363289 have introduced the pressure-sensitive carbon paper that scribbles inorganic fluorescent substance, though the duplication handwriting of its generation is stealthy, but the inorganic fluorescent substance dispersiveness is bad, the poor stability of formed coating system, the inorganic fluorescent substance kind is more single in addition, therefore raw material obtains easily, and the false proof usefulness of the fluorescent pressure-sensitive carbon paper of making of their is not high.
It is stealthy, numerous in variety the purpose of this invention is to provide a kind of duplication handwriting, and novel fluorescence pressure-sensitive carbon paper of efficient anti-counterfeiting performance and preparation method thereof is arranged.
The object of the present invention is achieved like this: the anti-fake fluorescent pressure-sensitive carbon paper that the present invention produces invisible duplication handwriting is by scribbling overleaf the colourless coating that contains organic Ultraluminescence complex or being printed on CB paper of the present invention (upper paper using) that the body paper of the colorless fluorescent printing ink that contains organic Ultraluminescence complex forms and scribbling or be not coated with adsorbent coating and the back side in the front and scribble the colourless coating that contains organic Ultraluminescence complex or be printed on the CF paper of the present invention (lower paper using) that body paper the CBF paper of the present invention (middle paper using) that forms and the body paper that scribbles or be not coated with the adsorbent coating in the front of the colorless fluorescent printing ink that contains organic Ultraluminescence complex form and consist of. The composition (weight ratio) that contains organic Ultraluminescence complex colorless coating is the organic ultraviolet fluorescence complex:buffer:adhesive:auxiliary agent=10:2～3:0.6～1.5:0.2～1, coating weight are 5 ± 2g/m2The composition of colorless fluorescent printing ink (weight ratio) is the organic ultraviolet fluorescence complex: wax: plasticizer: mineral oil or vegetable oil: the organic gel pledge: inorganic filler=15～40: 5～30: 1～10: 0～40: 10～40: 1～10; The composition of adsorbent coating (weight ratio) is an adsorbent: adhesive: inorganic filler=100: 10～20: 5～25.

The preparation method of the used organic ultraviolet fluorescence complex of the present invention had report in many documents, as D.E.Williams, and Analytical Chemistry, 43 (1); B.Budesinsky, Anal.Chim.Acta, 42,455-465; T.Shigematsu, Ahal.Chim.Acta, 46,101-106; R.P.Fisher, AnalyticalChemistry, 43 (3), 454-), Gede Anti-fake Tech. Co., Nankai Univ. is existing to produce.Other component raw materials all can be from commercially available acquisition.
Making fluorescent pressure-sensitive carbon paper of the present invention has following two kinds of methods, can select wherein any one for use.
First method, earlier the organic ultraviolet fluorescence complex is wrapped up with microcapsules, be equipped with buffer, adhesive and the auxiliary agent of regulation ratio consumption again, be made into the colourless coating (solid content is 25 ± 5%) of coating usefulness, with Kohler coater above-mentioned coating be uniformly applied to the commercially available common body paper back side respectively at last and promptly make CB paper of the present invention and CBF paper respectively with the positive body paper back side that has scribbled the adsorbent coating identical with CF paper.With adsorbent and adhesive and inorganic filler to scale, and add certain water gaging and mix that to make solid content be 45 ± 5% coating, again this coating evenly is coated onto commercially available common body paper front with knife type coater and promptly makes CF paper of the present invention, or be CF paper of the present invention directly with commercially available common body paper.
Second method, with bag or be not enclosed with the organic ultraviolet fluorescence complex of microcapsules and wax, plasticizer, mineral oil and/or vegetable oil, organic gel pledge and the inorganic filler of regulation ratio consumption mixes, grinds and make colorless fluorescent printing ink, with printing equipment this printing ink is imprinted on the commercially available common body paper back side respectively again and promptly makes CB paper of the present invention and CBF paper respectively with the body paper back side that the front has scribbled identical adsorbent coating with CF paper.The same first method of the making of CF paper.
The preparation of microcapsules can be adopted melamine to add formaldehyde or urea to add the in-situ polymerization method of formaldehyde or adopt polyisocyanates to add known methods such as the interfacial polymerization of amine or gelatin-gum arabic complex coacervation among the present invention.
When on CB paper of the present invention, writing or right with typewriter typewriting with pen, the colourless coating that contains the organic ultraviolet fluorescence complex can be transferred to down on one page paper, and by the CBF paper and the imbibition of CF paper institute of one page down, but under visible light, do not show any writing, when writing place or typewriting place, but demonstrate the fluorescent writing of distinct color immediately with uviol lamp (common detect counterfeit money machine) irradiation.
Compared with prior art, the advantage that the present invention has is: because the duplication handwriting that the present invention in use produces is stealthy, forge the personator and be difficult to find, almost stopped the generation of illegal activities such as personation signature, correction bill, improved false proof usefulness greatly.In addition because organic ultraviolet fluorescence complex of the present invention is easier to be littler by porphyrize, particle than inorganic fluorescent pigment, and dispersed, compatibility is all good, therefore, the coating or the printing ink fineness that are made by it are good, and uniform and stable.Thereby the pressure-sensitive copy paper and coating that makes with this coating or printing ink or the slickness and the wear-resisting wiping of ink film are all good, thus make invisible fluorescent duplicated writing link up, smooth.On the other hand, because inorganic fluorescent pigment kind is more single, the emission spectrum scope is narrower, all be jaundice, green, blue-fluorescence mostly, and organic ultraviolet fluorescence complex of the present invention is numerous in variety, jaundice look, green, blue-fluorescence are not only arranged, and more has to send out hunting pink fluorescence.Therefore, if CBF or CF are body paper with the coated paper that adds fluorescent whitening agent, adopt the coating of organic Ultraluminescence complex that contains of the present invention than more obvious fluorescent effect being arranged with the coating that contains inorganic fluorescent pigment.It is big to add the synthetic difficulty of organic ultraviolet fluorescence complex, and raw material is difficult for obtaining, and therefore, its anti-counterfeiting performance is far superior to the fluorescent pressure-sensitive carbon paper with existing other fluorescent material making.
