Description
Technical field
The constituent of the relevant jetting ink of the present invention is improved, and aims to provide a kind of jetting ink that is applicable to colored filter and has developing function.
Background technology
Generally speaking, the primary member of liquid crystal indicator is by the following subtend configuration in the tool gap of two plate electrode substrates of the picture element (pixel) that has the mutual subtend configuration that is formed by electrode separately, during this time the crack around edge sealing and the double team liquid crystal layer constitutes.In liquid crystal indicator; Particularly can show in the liquid crystal indicator of any chromatic image picture; Generally can use colored filter, colored filter on arbitrary plate base of two plate electrode substrates, possess R, G, B (red, green, blue) three primary colors or corresponding to each picture element can be chromatic the configuration of polychrome form and aspect dyeing element.
In the manufacturing method of color filters, have on by pigmented layer dispersed color with the colo(u)rant dispersion method that forms colored filter, on by pigmented layer dispersed dye with the dyestuff dispersion method that forms colored filter or with electricity the electricity that forms colored filter method or the illuminating colour colored filter used with the press plate of intaglio plate or lithographic plate makes ink printing on substrate to form all commercializations of print process of colored filter.But; In this type of previous method of manufacture; Because all use repeatedly micro-photographing process (Lithography process) and etch process in the colored filter manufacturing engineerings, the processing procedure of colored filter contains very miscellaneous problem, and for the correspondence picture element size of miniaturization more and more; Further require the precision of little shadow and etch process, and have the problem that is difficult for reaching simultaneously this excellent precision and rate of good quality rate.And this little shadow and etch process need more than the triplicate at least, producing R, G, B trichromatic colored filter, so processing procedure is numerous and diverse and cost also with increase.
Recently, the someone uses ink jet method (Inkjet printing) to make colored filter.It mainly comprises the following steps: on transparency carrier 11, to form the black matrix layer 12 and first photoresist layer 13 successively, shown in Figure 1A; To this 13 exposures of first photoresist layer and development, shown in Figure 1B, to this 13 exposures of first photoresist layer and development, form the photoresistance matrix 131 of plural patterning by light shield by light shield.Through this step, with the design transfer that is had on the light shield to this photoresistance matrix 131.
Afterwards this black matrix layer 12 is carried out etching, obtains the black matrix 121 of patterning, and after remove remaining photoresistance matrix 131 fully, shown in Fig. 1 C.By ink jet method ink being injected to deceive between the matrix 121 again; Shown in Fig. 1 D; Utilize ink discharge device; For example Thermal Bubble Ink-jet Printer device (Thermal Bubble Ink Jet Printing Apparatus) or piezoelectric ink jet device (Piezoelectric Ink Jet Printing Apparatus) inject the color ink of needs in the space between the black matrix 121 with little liquid 15, and the little liquid 15 of this plural number becomes ink 16 in this space endomixis.Shown in Fig. 1 E, utilize solidification equipment, for example heating unit or light-emitting device; These ink 16 oven dry or commissure or the two are had concurrently; To form color layers 17, shown in Fig. 1 F, this color layers 17 can be redness; Correspondingly, other blue color layers and green color layers are formed on a side of this beauty's chromatograph successively.
But make in the colored filter with ink-jetting style at this type of; For avoiding ink between each black matrix before uncured; Have color and mix mixing each other, and exist assertive colours to reproduce the problem of difficulty, so when ink-jet, can control the height that the volume of little liquid injection can not surpass black matrix; This color layers 17 is formed shown in Fig. 1 F; This color layers 17 forms dimpling shape and both sides and 121 in black matrix and is formed with breach 171, can disturb the normal operation of liquid crystal indicator, can't present the color scheme in the ideal.
Summary of the invention
In view of this, the present invention aims to provide a kind of jetting ink that is applicable to colored filter and has developing function; Take off purpose on reaching, this jetting ink is made up of the solvent and the additive of macromolecule resin, pigment, sensitization initiator, monomer, three kinds of different boiling; Wherein, the viscosity of this jetting ink is about 10～25mPa.s, and solid content is about 20% to 35% weight percent, and constitutes a kind of jetting ink with developing function.

Embodiment
For making your inspector know major technique content of the present invention, and embodiment, cooperate graphic explanation following now:
Jetting ink of the present invention; Basically form by the solvent (Solvent) and the additive (Additives) of macromolecule resin (Resin), pigment (Pigment), sensitization initiator (Photo initiator), monomer (Monomer), three kinds of different boiling; Be a kind of jetting ink that is applicable to colored filter; And the viscosity of this jetting ink is about 10～25mPa.s, and solid content is about 20% to 35% weight percent; Wherein:
The function of macromolecule resin (Resin) is tack, development property, pigment-dispersing, flowability, thermotolerance, endurance, analytic ability; The function of pigment (Pigment) is painted and colorization; The function of sensitization initiator (Photo initiator) is photobehavior, analytic ability; The function of monomer (Monomer) is tack, development property, analytic ability; The function of solvent (Solvent) is viscosity and coating character; The function of additive (Additives) then is coating, leveling characteristics and whipability.
The function of macromolecule resin (Resin) is tack, development property, pigment-dispersing, flowability, thermotolerance, endurance, analytic ability; Generally can be for containing carboxylic acid group's (COOH) polymkeric substance or multipolymer; Like resins such as acryl (Acrylic) resin, acryl-epoxy (Epoxy) resin, acryl-Mei Nai ware (Melamine) resin, acryl-vinylbenzene (Styrene) resin, phenol-phenolic aldehyde (Phenolic Aldehyde) resins; Or any mixing of above resin, but not as limit.Macromolecule resin (Resin) is about 10% to 25% weight percent in this jetting ink, and operating weight molecular-weight average (Mw) is lower than 50,000, better below 20,000.
The function of monomer (Monomer) is tack, development property, analytic ability; Generally can mixing for water-soluble monomer (water-soluble monomer) or water-insoluble monomer (water-insolubleMonomer) and water-soluble monomer (water-soluble monomer); This water-soluble monomer can be the monomer of T 46155 (being called for short EO) and polyoxypropylene (being called for short PO); And this water-insoluble monomer can be penta erythritol triacrylate, trimethylammonium ether propane triacrylate, trimethylammonium ether propane trimethyl acrylic ester, three; Two-ethanol isocyanic ester triacrylate, two; Trihydroxymethyl propane tetraacrylate, diisoamyl tetrol five propenoate, five propenoate, tetraacethyl isoamyl tetrol, six acetate, two own tetrols, six acetate diisoamyl tetrols or be any of the few body of multiple functional radical monomer, the tree-shaped/many clumps of a small bundle of straw, etc. for silkworms to spin cocoons on propenoate, the many clumps of a small bundle of straw, etc. for silkworms to spin cocoons on polyether acrylates, aethylis carbamas, and the weight percent that this water-soluble monomer accounts for total monomer is more than 10%; And monomer is about 5% to 15% weight percent in this jetting ink.
