Abstract
The present invention consists of at least three coupons, the upper coupon is primary paper with one color forming layer coated on its back side, the middle coupon is primary paper with one color developing layer coated on its upper side and one color forming layer coated on its back side, and the last coupon is primary paper with one color developing layer coated on its upper side. By utilizing microcapsules to develop different colors in its color forming layer, so that the color developing side is different from the color forming layer in color to reach the aim of preventing imitation.
Description
The invention belongs to a kind of color-developing anti-fake pressure-sensitive paper and production method thereof.
Existing no carbon paper is single colour developing mark, and is not ideal enough aspect false proof, anti-correction, is easy on the market just to find same paper to forge, and is easy to alter.
The purpose of this invention is to provide a kind of color-developing anti-fake pressure-sensitive paper, adopt the different microcavity capsules that develop the color colors to adjust the chromonic layer of the colour developing mark of different colours more than two kinds respectively, the color that color development face and chromonic layer are sent out is inconsistent, and reaches false proof purpose.
Another object of the present invention provides a kind of production method of color-developing anti-fake pressure-sensitive paper.
A further object of the present invention provides a kind of using method of color-developing anti-fake pressure-sensitive paper.
The invention provides a kind of color-developing anti-fake pressure-sensitive paper, become by three joint groups at least, go up one most and forms back side coating one deck chromonic layer of body paper by body paper and chromonic layer; Middle connection is made up of color layer, body paper and chromonic layer, body paper front surface coated one deck color layer, and the back side applies one deck chromonic layer; Last connection is made up of color layer and body paper, at front surface coated one deck color layer of body paper.

Color-developing anti-fake pressure-sensitive paper of the present invention gather leaves of a book print or write after have the look mark of two or more colour developing colors at least.
The present invention is by the microcapsules of different colour developing colors, adjust the chromonic layer of the colour developing mark of different colours more than two kinds respectively, by gathering leaves of a book more than three or three, make to join and be coupled to rare colour developing look mark more than two kinds, commensurate or different personnel do not have specific connection number, the holder of a certain receipts or other documents in duplicate is difficult to find again and original same paper is changed or forged, and plays anti-fake effect well.
Below in conjunction with embodiment the present invention is elaborated:
Fig. 1 is a product structure schematic diagram of the present invention.
The present invention uses by gathering leaves of a book simultaneously more than three or three as shown in Figure 1, and to go up one most be to apply the chromonic layer 2 that one deck has the microcapsules that include pigment at the back side of body paper 1; Middle connection is the front surface coated one deck color layer 3 at body paper 1, the back side applies the chromonic layer 4 that one deck has microcapsules, the color that the microcapsules of chromonic layer 4 include pigment is different with the color that chromonic layer 2 microcapsules include pigment, can mix the chromonic layer of the colour developing mark of different colours more than two kinds; Last connection is the front surface coated one deck color layer 3 at body paper 1.Owing to, make to join to be coupled to rare colour developing look mark more than two kinds by gathering leaves of a book more than three or three.
One, positive coating materials of preparation and coating
Adopt raw material and charging sequence to be: to get water 30g, polyacrylic acid 3g, kaolin 23g, zinc salicylate resin 8g, carboxylic styrene butadiene latex 13g by weight; Add at normal temperatures entry, polyacrylic acid, kaolin high speed dispersion good after, mix after adding zinc salicylate resin and carboxylic styrene butadiene latex again.The coating that mixes by 2-10g/m
2Coating weight be coated on the body paper front dry 1-5min under 40-140 ℃ of temperature afterwards.
Two, preparation CB coating and coating
The raw material and the charging sequence that adopt are: the 40g that fetches water by weight, polyacrylic acid 3g, starch interval dose 9g, microcapsules 45g, carboxylic styrene butadiene latex 7g, the color of microcapsules can be selected different colors as required.Earlier water, polyacrylic acid, starch interval dose, microcapsules and carboxylic styrene butadiene latex are mixed at normal temperatures stirring evenly, mixed coating is pressed 2-10g/m
2Coating weight be coated in the back side of body paper, and under 40-140 ℃ of temperature dry 1-5min.
Three, the processing method of middle connection paper
Take to carry out earlier the coating of the positive coating materials of body paper, and behind dry 1-5min under the 40-140 ℃ of temperature, carry out the coating of CB coating again, and then under 40-140 ℃ of temperature dry 1-5min.
The present invention is mainly used in bill false proof of multi-joint carbon paper, and this paper is to reach false proof purpose by the different colour developing of microcapsules.According to different needs, make the microcapsules of various special color development form and aspect, be coated in the body paper back side and form chromonic layer, through joining connection, after writing or printing, owing to there is the CB coating special paper different above each to have the positive colour developing mark that shows different colours more than two kinds to I haven't seen you for ages with another page, commensurate or different personnel do not have specific connection number, and the holder of a certain receipts or other documents in duplicate is difficult to find and same paper is changed or conduct is made.
