Abstract
A kind of thermochromic printing ink is a colour-changing agent with iodine mercury acid copper and Mercuric Silver Iodide, serves as to link agent with oxidation drying type synthetic resins, is equipped with additives such as viscosity modifier, can obtain the good fast dried color shifting ink of printing adaptability.The present invention prints all available intaglio plate of general stock or silk-screen technology, have significantly two variable colors or changeable chromatic effect, strong adhesion, ageing-resistant, it is very little influenced by light, wet, acid etc., it is up to ten thousand time to repeat variable color, is widely used in the false proof etc. of the surface temperature indication and the packing of product, trade mark.
Description
The present invention relates to a kind of printing-ink of the variable color along with temperature variation.
At present, photochromic printing-ink of the prior art, fatiguability, aging, variable color sensitivity is low, and variable color need be used uviolizing, use inconvenience.Existing liquid crystal heat colour-changed printing ink, its ageing resistance is also relatively poor, because discoloring temperature is too low, is generally 20～40 ℃, when envrionment temperature is higher than its discoloring temperature, is difficult to observe colour-change.Compounds such as iodine mercury acid copper, Mercuric Silver Iodide have 40～70 ℃ discoloring temperature, and variable color is reversible, sensitive, is used as camouflage paint and coating, but since its difficulty satisfy printing condition, thereby can not be widely used.Except that liquid crystal heat colour-changed printing ink, above-mentioned prior art also has a common defective, i.e. its variable color is single, is monotropic look, when waiting special marking, easily by imitated, and to the selection of stock bigger limitation is arranged as false proof.
The objective of the invention is to avoid above-mentioned weak point of the prior art, and provide a kind of all available intaglio plate of general stock or silk-screen technology are printed, have double-colored or the polychrome color changeable effect, variable color is obvious, sensitive, rapid, good stability, strong adhesion, ageing resistance is strong, can repeat repeatedly variable color, the thermochromic printing ink of strong interference immunity.
Purpose of the present invention can reach by following measure:
A kind of thermochromic printing ink comprises colour-changing agent, and its special character is, it also comprises binding agent and additive, described colour-changing agent is iodine mercury copper and Mercuric Silver Iodide mixture, and described binding agent is an oxidation drying type synthetic resins, and described additive comprises viscosity modifier.
The per-cent of colour-changing agent of the present invention, binding agent, additive consists of,
Iodine mercury acid copper 10～50% Mercuric Silver Iodides 10～50%
Link agent 35～70% additives 1～7.5%
Additive of the present invention also can comprise tensio-active agent, defoamer.
Additive of the present invention also can comprise siccative.
The invention will be further described below in conjunction with specific embodiment:
The present invention with the mixture of iodine mercury acid copper and Mercuric Silver Iodide as colour-changing agent; adopt the good oxidation drying type synthetic resins of printing performance as linking agent; so that colour-changing agent is not oxidized in printing ink manufacturing and drying process, do the back and form compact protective film, suppress variable color and decompose.The adding of additive can make the present invention can adopt silk screen and gravure machinery to carry out meticulous and printing continuously to writings and image, and general stock is obtained better fastness.Binding agent of the present invention can be adopted oxidation drying type modified alkyd resin or acrylic resin etc., but links agent double as antioxidant; Additive can adopt printing ink Synergist S-421 95s such as viscosity modifier, tensio-active agent, defoamer, siccative as required, and wherein, viscosity modifier is the important additives of regulating printing adaptability in the ink formulations.When printing ink is rare and sticking, can select for use low viscous Synolac or high boiling paraffin wet goods that aluminium salt such as eight aluminium carbonates are disperseed collagen, be formed with denseness and noncohesive auxiliary agent; When printing ink is thick and sticky, can directly add ink oil.Defoamer of the present invention, tensio-active agent can be selected tbp or adjacent benzene dibutylester etc. for use; Siccative can be selected cobalt, manganese or rare earth drier for use.
Formula constituent of the present invention is:
Iodine mercury acid copper 10～50% Mercuric Silver Iodides 10～50%
Link agent 35～70% additives 1～7.5%
Wherein, additive is when choosing, and viscosity modifier consumption in formula constituent is generally 1～6%, is the best with 3%; Defoamer, tensio-active agent are generally 0～1%, are the best with 0.2%; Siccative is generally 0～0.5%, is the best with 0.05%.To provide two concrete prescriptions of the present invention below:
Example 1: iodine mercury acid copper 10.58% Mercuric Silver Iodide 42.33%
Synolac 42.33% ink oil 2.64%
Adjacent benzene dibutylester 0.53% cobalt 1.59%
Above-mentioned raw materials is mixed with agitator, disperse with three-roller, gained printing ink all has good printing adaptability with 300 order screen paintings to various paper.Discoloring temperature and form and aspect are:
In the time of 51 ℃, by orange become orange red; In the time of 65 ℃, by the orange red purplish grey that becomes.
Example 2: iodine mercury acid copper 34.06% Mercuric Silver Iodide 14.60%
Synolac 48.66% C8 fatty alcohol-polyoxyethylene ether 0.49%
Tbp 0.25% cobalt 0.97%
Manganese 0.97%
Above-mentioned raw materials is ground the dispersion back all can be printed on surfaces such as paper, timber, iron sheet, duroplastss with 250 order silk screens.Discoloring temperature and form and aspect are:
In the time of 50 ℃ by the orange red redness that becomes; Become puce by redness in the time of 64 ℃.
During check,, promptly produce colour-change 1～2 second, after temperature reduces, will recover primary colors with heating such as cigarette end, match, lighter, hot water.
The present invention compared with prior art has following advantage:
1, all available intaglio plate or silk-screen technology are printed to general stock.
2, in 40～70 ℃ of scopes, have significantly two variable colors or changeable chromatic effect.
3, the color differentiation is rapid, sensitive, is easy to distinguish.
4, good stability, resistance to ag(e)ing is strong, and the attachment fastness height repeats variable color up to ten thousand times 100 ℃ of temperature with interior.
5, strong interference immunity, it is little affected by light, wet, acid etc., can be widely used in the false proof etc. of surface temperature indication and the packing of product, trade mark.
