Description
Technical field
The present invention relates to microparticle dispersion liquid for inkjet apparatus.
Background technology
In the display panels (LCD), for the thickness homogeneous that keeps 2 liquid crystal layers between substrate and constant and use spacer beads (spacer beads).This spacer beads has inorganic particulate or organic filler, inorganic organic composite particle etc.Inorganic particulate is generally stone, thereby causes alignment films or CF etc. are caused physical damnification and produce the result of defective, and is unsatisfactory as spacer beads.Organic filler is generally softer, therefore needs significantly to increase to scatter number, and image quality descends.In addition, because therefore poor heat resistance lacks long-term reliability.Based on these situations, spacer beads generally is extensive use of and shows suitable hardness and inorganic organic composite particle of nerve.
In addition, as the collocation method of spacer beads, adopted distribution method in the past.But in this distribution method, therefore also configuration space pearl in pixel takes place the decline of display qualities such as contrast to occur from sept surface or inner light leak.In order to suppress this problem, to attempt sept optionally is disposed at light shielding part, ink-jet method is a kind of method wherein of inquiring into.
The Jap.P. spy opens among the 2007-47773, display body with particulate sept dispersion liquid in, adopt boiling point more than 200 ℃ and the solvent of surface tension more than 42mN/m as dispersion medium.The Jap.P. spy opens among the 2006-209105, display body with particulate sept dispersion liquid in, adopt receding contact angle for substrate more than 5 degree and the contained dispersion medium of water below 10 weight %.
The Jap.P. spy opens among the 2006-171343 and puts down in writing, use in the sept dispersion liquid in the liquid crystal indicator manufacturing, the sept particle is the hollow-particle that has the space in inside, and proportion is below 1.3,10% compressive modulus of elasticity is 2000～15000MPa, with the difference in specific gravity of dispersion medium below 0.05.
Object lesson as the sept dispersion liquid, the Jap.P. spy opens the sept dispersion liquid of having put down in writing proportion 1.08/ viscosity 19mPas among the 2007-47773, the sept dispersion liquid of proportion 1.062/ viscosity 8.0mPas, but does not have record to be implemented in the dispersion liquid of the higher proportion of realization under the lower viscosity.
Open the object lesson of the dispersion medium of putting down in writing among the 2006-209105 as the Jap.P. spy, put down in writing the sept dispersion liquid of proportion 1.113/ viscosity 23mPas, but do not have record to be implemented in the dispersion liquid of the higher proportion of realization under the lower viscosity.
Open the object lesson of the dispersion medium of putting down in writing among the 2006-171343 as the Jap.P. spy, put down in writing the sept dispersion liquid of proportion 1.063/ viscosity 17.5mPas, but do not have record to be implemented in the dispersion liquid of the higher proportion of realization under the lower viscosity.
The announcement of invention
But, the known bigger sept dispersion of nano-particles liquid of proportion such as inorganic organic composite particle that scatter by ink-jet method form under the situation of sept, in the dispersion liquid in the past, if make the proportion of the nearly inorganic organic composite particle of liquor ratio reclosing, then viscosity increases, becoming is difficult to spue from nozzle, and distribution can't be carried out well.
Problem of the present invention is, makes microparticle dispersion liquid for inkjet apparatus also can easily spue from nozzle under the situation that is dispersed with the bigger particulate of proportion, scatters well.
The present invention relates to microparticle dispersion liquid for inkjet apparatus, it is characterized in that, comprise dispersion medium, be dissolved in the sugar of this dispersion medium and at least one side and the particulate in the sugar alcohol.
Find that by the present invention for example the aqueous solution by mixing sugar or sugar alcohol is as the dispersion medium of ink discharge device usefulness sept particle dispersion, can realize that bigger the stable of particulate of proportion that the technology by in the past is difficult to realize spues.
That is, the inventor has carried out various researchs to the bigger particulate of various particulates, particularly proportion, found that in most cases and can't suitably carry out spuing of particulate.For example, the proportion of each dispersion medium of putting down in writing in each citing document of enumerating in the project to background technology and the relation of viscosity have been carried out map (Fig. 1).Found that along with the rising of the proportion of dispersion medium, its viscosity also rises.
Jetted ink can be stablized the range of viscosities that spues according to the kind of ink gun and difference is roughly 5～25mPas (20 ℃).In addition, such as in the patent documentation 3 record, the difference in specific gravity of particulate and dispersion medium is the smaller the better, if like this, thinks that then the dispersion medium of particulate of branch bulk specific gravity 1.15～1.25 better is to have 1.15～1.25 proportion.This with Fig. 1 in the zone that surrounds by dotted line (proportion be 1.15～1.25 and viscosity be 5～25mPas) corresponding.But each dispersion medium of putting down in writing in the citing document can't be realized such condition.
Therefore, after the inventor sought various raw materials, the result had realized reducing viscosity by the aqueous solution of using sugar, sugar alcohol in the proportion that strengthens dispersion liquid.And after making that particulate is actual and being scattered in this dispersion medium and spuing from inkjet nozzle, confirmation can stably spue and scatter the sept particle, thereby has finished the present invention.
