Abstract
On the back faces of the upper paper and the medium paper of pressure-sensitive carbon paper is coated or printed with coating or printing ink which contains organic ultraviolet fluorescent mixing material show, so that the characters on the carbon paper by hand writing or typewriting can fluorescent colour under the shining of ultraviolet light. It has the advantage of simple using, clear and beauty paper-face etc.. Because organic ultraviolet fluorescent mixing material has good dispersing performance, multiple varities, and is difficult to synthesize and obtain its raw material, so that its anti-fake function is far better than that of inorganic fluorescent pigment.
Description
The invention belongs to and utilize the feasible displayable carbon paper of color that is covering of pressure, promptly be commonly called as pressure-sensitive carbon paper, and preparation method thereof.
At present in the carbon paper of the employed multi-joint manifolding receipts in field such as commerce, finance, finance, roughly there is folder page to be coated with carbon (pigment) carbon paper, to carry on the back and be coated with carbon (pigment) carbon paper and NCR three classes.The first two class is coated with carbon carbon paper in use many defectives, few as manifolding connection number, uses trouble, can not be applicable to office automation, and paper is not attractive in appearance, and therefore the connection of the upper and lower end of easy set-off bill etc. when writing is eliminated just gradually.The substitute is NCR, it is easy to use, paper is attractive in appearance, writes Shi Buhui and produces the set-off phenomenon, and the multi-joint manifolding of energy is applicable to office automation, adopts in the bill of many industries at present.Yet the carbon paper of above-mentioned existing type does not nearly all have false proof function, anti-counterfeiting performance is very weak in other words, is forged by the offender easily.For this reason, the someone develops fluorescent pressure-sensitive carbon paper, to strengthen the anti-counterfeiting performance of manifolding bill.JP05-214278 has introduced a kind of pressure-sensitive carbon paper that scribbles common coloured organic fluorescent dye, because these organic fluorescent dyes have color, does not possess disguise, and raw material obtains easily in addition, so the bill of making of this paper still easily is forged.JP59-98892 and JP04-363289 have introduced the pressure-sensitive carbon paper that scribbles inorganic fluorescent substance respectively.The writing of this class carbon paper can show certain fluorescence color under the UV-irradiation of particular range of wavelengths.Because fluorescence color is hidden under visible light, has improved the anti-counterfeiting performance of pressure-sensitive carbon paper.Yet, the particle size of inorganic fluorescent pigment is generally bigger, if grind too carefully, can destroy its microstructure again and luminosity is reduced, therefore, coating that is made by inorganic fluorescent pigment or distributes ink and stability are all poor, perhaps fluorescent brightness is low, and is poor for applicability, again because its kind is single, raw material also obtains easily, so its anti-counterfeiting performance is still not ideal enough.
It is uniform and stable to the purpose of this invention is to provide a kind of Bulk coat system, also is implied with fluorescent pressure-sensitive carbon paper high brightness fluorescence, high anti-counterfeiting performance and preparation method thereof in the duplication handwriting of showing one's color.
