Abstract
The invention provides a printing ink composition for ink jet recording. The printing ink composition comprises the following components by weight percentage: 0.1 to 8.0 percent of dye and 60.0 to 98.0 percent of organic solvent. The printing ink composition can be applied to a water type ink jet printing device for printing on hydrophobic mediums such as glass, ceramics, metal and plastics.
Description
Technical field
The present invention relates to a kind of ink-jet recording device with ink composite and use the ink jet recording method of this ink composite, particularly can be at solvent-based ink composition of using on the water type ink-jet recording device and the ink jet recording method that on water type ink-jet recording device, prints with solvent-based ink composition.
Background technology
Ink-jet recording device can be divided into water type ink-jet recording device and solvent-borne type ink-jet recording device according to the type difference of employed ink composite.Wherein, water type ink-jet recording device uses with the water color ink of water as main solvent, and it is inner not corrosion-resistant with the contacted parts of printing ink.The solvent-borne type ink-jet recording device uses with the solvent type ink of organic solvent as main solvent, and it is inner all corrosion-resistant with the contacted parts of printing ink.
At present, use reaches its maturity and water type ink-jet recording device generally, but because of water in the employed water color ink has accounted for sizable ratio, therefore can only be used to be printed onto hydrophilic recording medium, on the hydrophobic recording medium such as glass, metal, pottery, plastics that is difficult to be printed onto water-fast surface, the printed image water tolerance that adds water color ink formation is also relatively poor, and this causes the application of water type ink-jet recording device to be subjected to limitation.
Though existing solvent type ink has excellent water tolerance; can be printed onto on the recording mediums such as glass, metal, pottery and plastics; but it can only be used for the solvent-borne type ink-jet printer usually, can occur shortcomings such as disconnected China ink, obstruction printhead, shutdown back start at intermittence fluency difference because of its physical and chemical parameter that can not adjust to the water type ink-jet printer that suits when being used for water type ink-jet printer.In addition, solvent-based inks also can cause corrosion to the parts that contact with printing ink in the not corrosion resistant water type printer usually.
Summary of the invention
The inkjet printing methods that order of the present invention is to provide the good solvent-based ink composition that can be used for water type inkjet-printing device of a kind of water resistance and uses this ink composite.
For realizing one of purpose of the present invention, one of technical scheme that the utility model provides is: composition for ink jet recording, contain: the water-insoluble dyestuff of 0.1～8.0 weight %; And 60.0～98.0 weight % organic solvent.
By in above-mentioned ink composite, improving the usage quantity of organic solvent, can make whole ink system transfer the hydrophobic system to by hydrophilic system, therefore can improve the water tolerance of ink composite, and then can use it on hydrophobic mediums such as glass, pottery, metal, plastics, to print.
Scheme is that the hydrogen bond value scope of organic solvent is between 12.0-19.0 preferably.The organic solvent corrodibility of hydrogen bond value in this scope is little, can make ink composite have less corrodibility, to be applicable to water type ink discharge device.
Better scheme is that organic solvent is selected from one or more the mixture in alcohol derivate, ether derivant or the ketone derivatives, to improve the wettability of ink composite, ink composite is obtained and the akin physico-chemical parameter of water type printing ink.
Better scheme is that dyestuff is selected from a kind of in solvent black 46, solvent black 29, solvent black 27, solvent black 28, solvent blue 5, solvent blue 4, solvent blue 70, solvent red 122, solvent red 119, solvent red 218, solvent red 124, solvent red 125, solvent red 49, solvent yellow 82, solvent yellow 19, the solvent yellow 79 or several mixing.Therefore above-mentioned dyestuff has excellent water tolerance, weather resisteant and have good solubility in organic solvent, can make ink composite have better water-fast, sun-proof performance and good fluency.
Again one preferably scheme be the tackiness agent that ink composite further comprises 1.0～20.0 weight %.Tackiness agent can guarantee that printing ink has the ability of certain sticking power and anti-physics or chemical action.
Better scheme is that tackiness agent is a spirit-soluble resin, because of itself and alcohol, pure ethers, ketone solvent etc. have good intermiscibility, can improve the tack of ink composite to hydrophobic medium.
Not bad scheme is that the viscosity of ink composite is 1～10Mpas, and the viscosity of this viscosity and corresponding common water-base ink is close, therefore can guarantee that ink composite has good fluency and stability when being used for water type inkjet-printing device.
Not bad scheme is that ink composite is further introduced deionized water, with the surface tension of controlling described ink composite between 29～38mN/m, so that the fluency of ink composite is better.
For realizing another object of the present invention, another technical scheme provided by the invention is: ink jet recording method, use aforementioned any ink composite to print on water type ink-jet recording device.
