Abstract
The present invention relates to magnetic ink, and especially a kind of magnetic ink with magnetism varying with temperature. The anti-fake mark printed with the anti-fake ink exhibits certain magnetism under the temperature lower than some specific value and possesses no magnetism under the temperature higher than the specific value. The specific value is designed based on specific requirement within 30-150 deg.c. The heat-sensitive magnetic anti-fake ink may be printed in different printing mode and may be in different colors, black, brown, blue, etc. The present invention raises anti-fake capacity.
Description
Technical field:
The present invention relates to a kind of magnetic ink, particularly relate to a kind of magnetic ink that its magnetic that has is changed, it can be used on the various printed matters, become a kind of anti-counterfeiting technology measure along with temperature variation.
Background technology:
Magnetic ink can trace back to the '30s in last century as anti-forgery ink, has been used for social life in a large number as a kind of false proof means, as dollar, bill, Valued Securities etc.Basic for checking that its marking has certain remanent magnetism and exists, reach the purpose of distinguishing true from false.Relative and other anti-counterfeiting technologies along with science and technology development, only depend on ' remanent magnetism ' false proof, can not add the condition element that more adds in advance, it is limited that anti-counterfeit capability just seems, the particularly appearance of reprography, a lot of copies all have certain ' magnetic ', make by single ' remanent magnetism ' also just to seem stiff barren as anti-counterfeiting characteristic; Make ' magnetic ink ' marking be used for machine recognition signal and information storage more.
Summary of the invention:
The objective of the invention is to overcome the traditional magnetic anti-forgery ink and check the characteristics of marking changing factor single (only remanent magnetism is), add the special magnetic substance of people after, increased the temperature factor when checking, thereby increased imitation difficulty greatly, improved anti-counterfeiting power.
The present invention is achieved in that
A kind of thermosensitive magnetism anti-forgery ink can detect the existence that is magnetic when being lower than certain specified temp, when surpassing specified temp, its magnetic disappears, and in the time of under temperature returns to specified temp, printing ink recovers magnetic again.
The specified temp that this thermosensitive magnetism anti-forgery ink magnetic changes designs as required, and scope is 30 ℃-150 ℃.
This thermosensitive magnetism anti-forgery ink can be relief printing plate, lithographic plate, intaglio plate, carved gravure, silk-screen ink.
This thermosensitive magnetism anti-forgery ink can be deceive, brown, blue, green, mauve printing ink.
This thermosensitive magnetism anti-forgery ink can add special magnetic substance (Curie temperature difference) when making printing ink because such material varies with temperature itself residual induction variation, so this temperature variation zone can be predetermined, therefore this printing ink can detect magnetic in the temperature province of setting, and then can not detect magnetic outside the temperature province of setting.
This special magnetic substance product can be heat-sensitive Mn-Zn ferrite material (soft magnetism), its product specification can for:
The heat sensitive ferrite magneticsubstance and the magnet of any Curie temperature in 30 ℃ of-150 ℃ of temperature ranges (or claiming Curie temperature) specification, technical characterstic meets following requirement:
1) the Curie temperature scope of thermosensitive magnetism material: 30 ℃-150 ℃.
2) magnetic permeability of thermosensitive magnetism material all can reach more than 3000, and the magnetic permeability velocity of variation is near the Curie temperature: 〉=140/ ℃
Above-mentioned magnetic substance product can be pressed the above-mentioned requirements manufacturing by the manufacturer of the industry.
Its marking normal temperature of this thermosensitive magnetism anti-forgery ink had down ' remanent magnetism " except that can changing, also can vary with temperature with external magnetic field, disappear until ' remanent magnetism ', and after temperature returns to normal temperature, its ' remanent magnetism ' is occurred.Make people can detect the existence that is magnetic at normal temperatures earlier; The temperature of using prevailing type of heating (as flatiron) to change the marking then is the temperature province that sets in advance, and carries out magnetic testing; Can detect does not have magnetic to exist, and the temperature that also can use the well heater (plate) of common adjustable temps to change the marking is the temperature province that sets in advance, and carries out magnetic testing and can detect and do not have magnetic to exist.Detect the existence that is magnetic at normal temperatures.The temperature that changes the marking rises to the zone that sets in advance, and carrying out the marking does not have magnetic.When temperature returns to normal temperature, can detect the existence that is magnetic again.The range of temperature of thermosensitive magnetism anti-forgery ink magnetic can be 30 ℃-150 ℃.The thermosensitive magnetism anti-forgery ink can be printing ink such as relief printing plate, lithographic plate, intaglio plate, carved gravure, silk screen.The thermosensitive magnetism anti-forgery ink can add pigment such as black, brown, blue, green, red and make various chromatic printing ink.
According to common printing ink manufacture method, in this thermosensitive magnetism anti-forgery ink, advance the various pigment of people and can be made into colored inks such as black, brown, blue, green, red.In printing ink, change resin, auxiliary agent, solvent etc. and connect material, can be made into flat board, flange, notch board (containing engraved copper-plate printing) screen printing ink.
The present invention has increased the temperature factor when checking, thereby increases imitation difficulty greatly, has improved anti-counterfeiting power.
