Description
Technical field
The present invention relates to a kind of composition, particularly a kind of ink composite having no irritating odor.
Background technology
At present, ink-jet cloth printing application is more and more wider, and its Application Areas comprises paper printing, plant printing, special material printing etc.Ink by chromoplastid (as pigment, dyestuff etc.), low-melting ink vehicle, fill out the uniform mixture that the materials such as (filling) material, additional material form, can print, and be dried being printed on body, be the pulpous state adherent that has color, there is certain degree of mobilization.Therefore, color (form and aspect), body bone (rheological property such as rare thick, degree of mobilization) and drying property are three most important performances of ink.The kind of ink is a lot, and physical properties is also different, and what have is very thick, very sticky, and have quite rare.What have makes low-melting ink vehicle with vegetables oil, somely makes low-melting ink vehicle with resin and solvent or water etc.These are all that the type and the drying means etc. that are stock, printing process, printing plate according to the object of printing decide
For the intaglio printing of flexible packages, for the flexographic printing of sanitary material, for the silk screen printing of metallograph, be conventionally known as for the ink jet printing of indoor and outdoors advertisement etc. the printing process that is suitable for nonabsorable printed medium.But, generally include solvent as toluene, ethyl acetate, methylethylketone, methyl iso-butyl ketone (MIBK) and pimelinketone for the ink composite of these printing processes.But, require as at the environmental concentration of numerical value according to the rules, because smell is installed the obligation of partial exhaust gas device and regular physical examination.Therefore, operation is very difficult.Therefore, require to have the ink of higher safety and health performance.Especially, unlike the intaglio printing of carrying out in special factory, flexographic printing and silk screen printing, ink jet printing, for common commercial office, requires to consider more safety, danger and taste.
In above situation, about the intaglio printing for flexible packages with for the flexographic printing of sanitary material, develop the non-toluene ink that does not comprise toluene that environmental concentration set(ting)value is little or comprised the water color ink of alcohol as main ingredient.
About ink jet printing, develop the ink that uses polyalkylene glycol solvent or hydrocarbon solvent.But such ink can not dissolve the surface of printed medium, therefore cause poor fixation performance and water tolerance.
In recent years, by being combined with nitrogen-containing heterocycle compound if 2-Pyrrolidone or METHYLPYRROLIDONE or lactone compound are as secondary solvent, developed and there is the solvent-laden ink that improves fixation performance and water tolerance.Strong solubleness, in some cases, need to consider these materials and taste.
But, ink of the prior art.To the control of material and stimulation, hazardous property smell, always desirable not to the utmost.
Summary of the invention
The object of the invention is to address the deficiencies of the prior art, a kind of have a small amount of smell, excellent safety and health performance, excellent resin dissolves degree, excellent printing stability and excellent drying property are provided, do not cause the corrosion in printer, at the excellent ink composite having no irritating odor with thering is good print of bonding performance to nonabsorable printed medium.
