Abstract
A kind of allochromatic ink paste belongs to the stamp-pad ink composition material.It is that to close mercury (II) acid with a kind of reversible thermochromism tetraiodo cuprous, with semi-drying oil abundant ground and mixed under paucidisperse agent condition by weight percentage, makes the variable color stamp-pad ink.The red pigment that also can in above-mentioned composition, add traditional ink paste.Made variable color stamp-pad ink is soaked porous plastics or moxa is made allochromatic ink paste.Have the redness identical with traditional ink paste with seal that allochromatic ink paste stays, but once being heated to about 70 ℃, promptly become black by redness, cooling recovers original redness again, and color transition is the repetition reversible.This allochromatic ink paste can be used for the various false proof occasions of seal that need.
Description
Allochromatic ink paste of the present invention belongs to the stamp-pad ink composition.
Seal is the conventional tag that unit or individual or group are used for the expression identity on certificate, file, letter, the bill etc., has obtained widespread use for a long time at home and abroad.At present both at home and abroad the used ink paste of seal generally all is to be base-material with the red pigment, be filler with potter's clay, moxa etc., directly modulates with semi-drying oil to form; Sometimes also available porous plastics is a stopping composition, pigment is allocated with semi-drying oil made stamp-pad ink earlier, then stamp-pad ink is soaked porous plastics.But, in today that the seal of vacation can look genuine fully, owing to there is not special ink paste to be limited, occur repeatedly, and be difficult to for the moment differentiate so copy the incident of seal, caused great harm and loss.
Purpose of the present invention just is to distinguish the true and false of the seal that stays effectively, and developed the ink paste that traditional seal is distinguished in a kind of special being convenient to for simple, convenient, and it had both had the identical redness of traditional ink paste, and the reversible thermochromism is arranged again.The seal that stays with this allochromatic ink paste can identify the true and false of this seal immediately.
The realization the solution of the present invention is: it is sour cuprous to close mercury (II) with a kind of tetraiodo with reversible thermochromic, Cu
2[HgI
4] be main colorant and semi-drying oil by weight: 30-70%; The ratio of 70-30%, and add the paucidisperse agent and mix and make the variable color stamp-pad ink.Also can close the sour cuprous Cu of mercury (II) at four sulphurs
2[HgI
4] with semi-drying oil in add a small amount of traditional ink paste and make the red pigment 5-10% of usefulness, add the paucidisperse agent again and mix and make the variable color stamp-pad ink.The variable color stamp-pad ink that makes is soaked porous plastics or moxa, just formed allochromatic ink paste of the present invention.
Allochromatic ink paste of the present invention has following advantage:
1, the color of the seal that stays with allochromatic ink paste of the present invention has the redness identical with traditional stamp-pad ink.
2, with the color of the left seal of allochromatic ink paste of the present invention, have tangible sensitive reversible thermochromism, these seals to about 70 ℃, can become black once heating by redness, be cooled to normal temperature after, revert to original redness again at once.
3, seal is become black and can be repeated reversible carrying out by the color transition that black becomes original redness again by redness.
4, allochromatic ink paste manufacturing process of the present invention is simple, and cost is low holds concurrently, and realizes easily.Can be used for special all false proof places of needs such as bank, security, stock, certificate, file, letter.
Embodiment:
1, it is sour cuprous to close mercury (II) by weight the tetraiodo of 30-60%, Cu
2[HgI
4] and the red pigment (5-10%) of 65-30% semi-drying oil and traditional usefulness, adding under the paucidisperse agent condition, fully grind, promptly make the composition material variable color stamp-pad ink of allochromatic ink paste of the present invention.The variable color stamp-pad ink that makes is soaked porous plastics or moxa, just made allochromatic ink paste of the present invention.
2, it is sour cuprous to close mercury (II) with the tetraiodo of weight ratio 30-70%, Cu
2[HgI
4] and the semi-drying oil of 70-30%, adding under the paucidisperse agent condition, fully ground and mixed, promptly make the composition material variable color stamp-pad ink of allochromatic ink paste of the present invention, the variable color stamp-pad ink is dropped on porous plastics or the moxa, make it to soak, just made allochromatic ink paste of the present invention.
Claims (2)
1, a kind of allochromatic ink paste, it is characterized in that, close the cuprous and semi-drying oil of mercury (II) acid by a kind of tetraiodo of reversible thermochromic, be the ratio of 30-70%: 70-30% by weight percentage, under paucidisperse agent condition, fully ground and mixed is made the variable color stamp-pad ink, then the variable color stamp-pad ink is soaked porous plastics or moxa, makes allochromatic ink paste.
According to the allochromatic ink paste of claim 1, it is characterized in that 2, the above-mentioned tetraiodo is closed in the cuprous and semi-drying oil of mercury (II) acid, can add the red pigment (5-10%) of a spot of traditional ink paste.
