In addition, as the concrete example of inorganic pigment, extender pigment, can enumerate titanium oxide, barium sulfate, calcium carbonate, zinc oxide, lead sulfate, yellow lead, zinc chrome, di-iron trioxide (Bengala) (red iron oxide (III)), cadmium red, ultramarine, dark purple, chrome oxide green, cobalt green, umber, titanium black, synthesize iron oxide black, carbon black etc.It should be noted that, the colouring agent coordinating in first and second composition for ink can be distinguished use separately, also can mix two or more uses.

About colouring agent, consider spray nozzle clogging when utilizing ink-jet method ejection composition for ink etc., preferably use together with macromolecule dispersing agent micronize decentralized stabilization to the particle below 100nm.That is, dispersant is in order to disperse colouring agent well and to coordinate in composition for ink as required.For example, as dispersant, can use the surfactant of cation system, anion system, nonionic system, both sexes, silicon-type, fluorine system etc.In surfactant, the high molecular surfactant (macromolecule dispersing agent) that preferred following illustration is such.That is, the polyoxyethylene alkyl ether class such as polyoxyethylene lauryl ether, polyoxyethylene octadecyl ether, polyoxyl 10 oleyl ether; The polyoxyethylene alkyl phenyl ether classes such as NONIN HS 240, polyoxyethylene nonylplenyl ether; The polyethylene glycol di such as polyethylene glycol dilaurate, polyglycol distearate class; Sorbitan fatty acid esters class; Fatty acid modified polyesters; The high molecular surfactants such as tertiary amine modified polyurethane.

Content when first and second composition for ink coordinates colouring agent, with respect to the solid constituent total amount in ink, conventionally with 1～60 quality %, preferably the ratio of 5～40 quality % coordinates colouring agent.If with respect to the solid constituent total amount in ink, the mixing ratio of colouring agent is less than 1 quality %, and when composition for ink is applied into regulation thickness, the transmission density of (being generally 0.1～2.0 μ m left and right) is not enough.On the contrary, if surpass 60 quality %, composition for ink is being coated in while making it curing on support base material, is likely paintedly filming poorly to the adaptation of support base material, and may become insufficient as the characteristic of filming of hardness of film etc.

In addition, at first and second composition for ink, can coordinate Photoepolymerizationinitiater initiater.About Photoepolymerizationinitiater initiater, except adhesive, different (for example radical polymerization of reaction formation of polyfunctional monomer, cationic polymerization etc.), it is also conceivable that the kind of each material is suitably selected, for example, can enumerate 1-hydroxy-cyclohexyl-benzophenone, 2,2-dimethoxy-1,2-diphenylethane-1-ketone, 2-methyl isophthalic acid-[4-(methyl sulfo-) phenyl]-2-morpholinyl propane-1-ketone, 2-benzyl-2-dimethylamino-1-(4-morpholinyl phenyl)-butane-1-ketone, 2-hydroxy-2-methyl-1-phenyl-propane-1-ketone, 1-[4-(2-hydroxyl-oxethyl) phenyl]-2-hydroxy-2-methyl-1-propane-1-ketone, 2,4,6-trimethylbenzoyl diphenyl-phosphine oxide, two acylphosphine oxides, benzoin ethyl ether, benzoin isobutyl ether, benzoin isopropyl ether, ITX, 2,4-diethyl thioxanthone, 2-(3-dimethylamino-2-hydroxyl propoxyl group)-3,4-dimethyl-9H-thioxanthones-9-ketone meso chloride, benzophenone, o-benzoyl yl benzoic acid methyl esters, 4-benzoyl-4 '-methyl-diphenyl sulfide, 3,3 ', 4,4 '-tetra-(tert-butyl hydroperoxide carbonyls), ESCAROL 507 ethyl ester, ESCAROL 507 isopentyl ester, 1,3,5-triacryl, six hydrogen-s-triazine, 2-[2-(5-methylfuran-2-yl) vinyl]-4, two (the trichloromethyl)-s-triazines of 6-, 2-[2-(furans-2-yl) vinyl]-4, two (the trichloromethyl)-s-triazines of 6-, toluyl carbamate, the Photoepolymerizationinitiater initiaters such as TMDPO.

In addition, in first and second composition for ink, can coordinate solvent.As solvent, such as using the ethylene glycol monoalkyl ether acetate classes such as ethylene glycol monomethyl ether acetate; The monoalkyl ethers of diethylene glycol such as diethylene glycol monomethyl ether, diethylene glycol monoethyl ether class; The monoalkyl ethers of diethylene glycol acetate esters such as diglycol monotertiary n-butyl ether acetic acid esters; The propylene-glycol monoalky lether such as propylene glycol methyl ether acetate, propylene glycol monoethyl ether acetate acetate esters; The high boiling solvent class of other ethers such as diethylene glycol dimethyl ether, gamma-butyrolacton etc. etc.

In order to obtain first and second composition for ink, mix respectively above-mentioned such basis, the reactive diluent that blending surface tension regulator, the lowering viscousity of take are object as required, as ink for inkjet, is mixed with and is applicable to the characteristic value of ejection characteristic continuously.Normally used ink gun, utilizes piezoelectric element work.Therefore, viscosity, when a China ink temperature is 20～45 ℃, is made as 5～30mPasec, and it is suitable that surface tension is made as 20～40N/m.In addition, the second composition for ink is with respect to the first painted static contact angle θ filming being formed by the first composition for ink _kneed to be preferably more than 40 ° for more than 35 °, by making the first composition for ink contain ink-resistant composition with respect to 100 mass parts of solid constituent in ink with the ratio of 0.01 mass parts～2 mass parts, can realize above-mentioned purpose.

In addition, for the support base material using when manufacturing colour filter, can transmitted light, be not particularly limited, such as the glass using in liquid crystal display etc. naturally much less, also can use can be at more than 90% transparent plastic sheet or films of transmissivity such as the acrylic resin of use in electronic paper etc., PET, PC, polyolefin.

In order to manufacture surface, there is the colour filter that uniform coloring is filmed, can to support base material, carry out surface treatment in advance, thereby the contact angle of first and second composition for ink and support base material is adjusted.The composition for ink that utilizes ink-jet method to be sprayed on support base material is liquid, so the surface tension that its surface tension and support base material have changes the degree of wetting expansion.Therefore, preferably as required support base material is carried out to surface treatment etc.The first composition for ink particularly, by the contact angle θ of the first composition for ink and support base material _lbeing made as 3 ° is applicable to above.If contact angle is lower than it, exceedingly wetting expansion of the drop of composition for ink on support base material, likely becomes and cannot control forming painted the filming of regulation.By painted, film while forming with straight line, this contact angle θ _lpreferred upper limit value be 25 °.If contact angle θ _lover 25 °, for example from the drop of the composition for ink of nozzle ejection, with linearity, arrange continuously while describing straight line, first drop on drop on base material can absorb after ejection drop and make drop concentrate on ad-hoc location, may form the situation of wetting expansion such, that drop is inhomogeneous of swelling that is called as.When forming painted the filming of grid style, contact angle θ _lpreferred upper limit value be 45 °.If surpass this higher limit, stained area may become unstable.On the other hand, about the contact angle θ of the second composition for ink and support base material _l, the viewpoint of solidifying the painting intermembrane space obtaining from landfill the first composition for ink, is not limited to this contact angle.In the situation that more paying attention to wetting expansion, preferred contact angle θ _lbe below 25 °.

As the surface preparation of support base material, can suitably utilize known method according to the kind of support base material.For example, except atmos plasma method, corona discharge, UV treatment, can also enumerating use, to apply in advance fluorine be ink-resistant aqua or the processing of using silane coupling agent etc.

When making to be sprayed on composition for ink on support base material and be solidified to form painted filming, different according to ink sensitivity, the first composition for ink is sprayed on support base material, the gap area of regulation is set and forms the first painted situation of filming, and this gap area is sprayed the second composition for ink, is adjacent to form the second painted situation of filming with the first painted filming, all ultraviolet irradiation amount can be made as to 200mJ/cm ²more than left and right, preferred 500mJ/cm ²above.This ultraviolet ray is irradiated, if for example use the ink discharge device of the stand (stage) with mounting support base material, the ejection of first and second composition for ink and ultraviolet ray are radiated to the enterprising line operate of same stand, do not need the handing-over etc. of the support base material of inter process, can efficiency manufacture well colour filter.

In addition, also can form by the first painted filming during the gap area forming, after ejection the first composition for ink, irradiation ultraviolet radiation solidify it, be adjacent to spray the first composition for ink with the first painted the filming obtaining, irradiation ultraviolet radiation solidifies it again, so just the ejection by the first composition for ink and the curing cycle forming of ultraviolet ray irradiation can be divided into a plurality of cycles to carry out.

In addition, also can on support base material, form after first and second painted filming, further irradiate enough ultraviolet rays.Ultraviolet irradiation amount is now 1000mJ/cm preferably ²above, but curing degree also depends on the kind of composition for ink, the illumination/output wavelength of exposure machine, thereby more than the light exposure that generally preferably the resid vol rate dependence of light exposure reduces.In addition, except ultraviolet curing, can also impose the heat treatment of 80 ℃～160 ℃ of left and right, thereby make further to improve as the durability of colour filter.

The specific embodiment

Below, use accompanying drawing to illustrate in greater detail the manufacture method of the colour filter in the present invention.It should be noted that, what illustrate below is the example of fabrication schedule, for the color of the composition for ink using, to not restrictions such as the painted color sequences of support base material.

[Production Example 1 of striated colour filter]

Fig. 3 represents to have red (R), the fabrication schedule of the striated colour filter of the painted areas of the painted striped style of filming arranged side by side of linearity of green (G), blue (B) this 3 look.First, as shown in Fig. 3 (A), will contain ink-resistant composition and ultraviolet curing composition and coordinate colouring agent and be colored as the first red composition for ink and be ejected in support base material from the China ink head of ink discharge device, drop is arranged with linearity.Now, with respect to the painted live width w filming ₀with 3 * w ₀the spacing mode of describing the line of composition for ink spray, carry out as required heat drying, remove volatile ingredient, then carry out ultraviolet ray and irradiate (UV1), form and there is the red colored of surperficial ink-resistant and film.

Then, will contain ink-resistant composition and ultraviolet curing composition and coordinate colouring agent and be colored as the first green composition for ink, as shown in Fig. 3 (B), be adjacent to ejection with red colored the filming of previous formation.Now with 3 * w ₀green ink composition delineation lines for spacing.Then carry out as required heat drying, carry out afterwards ultraviolet ray and irradiate (UV2), formation has the green coloring of surperficial ink-resistant and films.Herein, preformed red colored filming, can talk about the such effect in next door, and be endowed surperficial ink-resistant, thereby does not worry the green coloring significantly overlapping colour mixture problem obvious situation that becomes that causes of filming on red colored filming.In order not cause that adjacent painted overlapping increase of filming causes the problem of colour mixture, can be by green ink composition and the red colored static contact angle θ filming _kbe made as more than 35 °, be preferably made as more than 40 °.

Then, for being filmed and the green coloring rectilinear clearance region of filming and forming on support base material by red colored, as shown in Fig. 3 (c), ejection contains ultraviolet curing composition and coordinates colouring agent and be colored as the second blue composition for ink, carry out as required heat drying, carry out afterwards ultraviolet ray and irradiate (UV3), form live width w ₀blue-colored filming.Now, red colored the filming previously having formed filmed with green coloring, can talk about the such effect in next door, and be endowed surperficial ink-resistant, due to blue ink composition and these painted static contact angle θ filming _kbe more than 35 °, be preferably more than 40 °, therefore from the blue ink composition of nozzle ejection, can not exceed them.The situation that comprises previous green ink composition, confirms composition for ink and the painted static contact angle θ filming _kmethod, in the present invention, as pretest, as shown in Fig. 1 (B), with the identical condition of ultraviolet ray irradiation, heat drying with actual, in upper painted the filming that forms 1～5 μ m thickness of glass substrate (support base material), it is dripped to composition for ink 0.5 μ l, after 1 second, measure contact angle (23 ℃).

Each composition for ink of the red, green, blue applying on support base material, as shown in Fig. 1 (A), preferably with the contact angle θ of support base material _lbe below above 25 degree of 3 degree.If θ _lbe below 3 degree, wetting expansion excessively increases, and becomes and is difficult to control live width w ₀.On the contrary, if θ _lsurpass 25 degree, when ink-jet is described, easily produce protuberance, become and be difficult to describe good linearity.Each composition for ink of red, green, blue and the contact angle θ of support base material _lbe all the value being close, therefore can make the painted live width w filming obtaining after ultraviolet ray irradiation ₀homogeneous.It should be noted that, as confirming this contact angle θ _lmethod, for example, as pretest, as shown in Fig. 1 (A), support base material is dripped to composition for ink 0.5 μ l, after 1 second, measure contact angle (23 ℃).

In addition, for use red, green, blue each composition for ink, utilize ink-jet method to carry out the specific procedure that line drawing is painted, as shown in Figure 2, need to make drop land continuously, in order to form line, each drop after land need to be integrated.Therefore, the drop expansion diameter D while arriving support base material with respect to land, the spacing p between land drop ₁be set as D>p ₁.Drop expansion diameter D during these land is conventionally large than flying over from China ink head the liquid-drop diameter d coming.In addition, after land, and then after having consumed its kinetic energy, reach and contact substrate steady stability state.Therefore, after land, back to back expansion diameter is difficult to measure, and for this reason, uses and drops in the stable expansion diameter D observing later on substrate in land 1 ₁, be made as p ₁<D ₁.On the other hand, if p ₁>D ₁, each drop becomes independently point on base material.And then, with respect to 1 live width w as target ₀, regulate inkjet nozzle ejection 1 drop amount, ejection cycle, get the known ink-jet application conditions such as spacing, nozzle interval ready.It should be noted that, painted the filming of linearity can certainly utilize drop formation the painted of 1 line from a plurality of nozzle ejections to film.

Ultraviolet ray when obtaining each chromatic colorant and filming is irradiated can use known ultraviolet lamp, but use the ink discharge device of the stand that possesses mounting support base material, the ejection of composition for ink and ultraviolet ray are radiated in the situation of carrying out on same stand, also can use the LED-UV lamp that illumination is high.In addition, as shown in Fig. 3 (D), also can after obtaining blue-colored filming, carry out ultraviolet ray irradiation so that painted the filming whole of 3 looks further solidified, also can additional heat process.It should be noted that, the composition for ink being coated with on support base material after the 2nd look makes after its ultraviolet curing, adjacent painted its overlapping minimizing of filming, but also can make painted filming form energetically non-colored section completely non-conterminously.In this case, if using non-colored section as display pixel utilization, the demonstration that can obtain becoming clear.

[Production Example 2 of striated colour filter]

In addition, also can once spray the composition for ink of a plurality of colors, manufacture striated colour filter.That is, as shown in Fig. 4 (A), first in primary ink-jet application, will coordinate colouring agent and be colored as the first composition for ink of red (R), blue (B), green (G), take homochromy line as W _av3* 6[W _av3the mean value as the live width of the painted areas of 3 looks of target; W _av3=(w _r+ w _g+ w _b)/3] the mode of spacing, with the order ejection simultaneously side by side of R, G, B, irradiation ultraviolet radiation forms wire (UV1) by each painted filming.Then, gap area to the linearity forming between filming by above-mentioned each chromatic colorant being formed by the first composition for ink, as shown in Fig. 4 (B), spray the second composition for ink that coordinates colouring agent and be coloured to red (R), blue (B), green (G), irradiation ultraviolet radiation forms (UV2) by each painted filming with wire.Primary coating and secondary coating all can be carried out heat drying as required, remove volatile ingredient, then carry out ultraviolet ray and irradiate, described in above-mentioned example.In this wise, can will be divided into the painted even column of filming of linearity and 2 ink-jet application of odd column as elementary cell, forming the painted of 3 looks films, according to the area of support base material, repeat as required this elementary cell, or increase the colour filter that a China ink numeral system is made the painted areas that possesses striped style.It should be noted that, after forming each painted filming, can be further whole irradiation ultraviolet radiation carry out whole curing, also can heat treated.

[Production Example 3 of striated colour filter]

And then, for example also can add the white (W) of the transparent resin composition for ink that does not contain coloring pigment or the yellow ink composition (Y) that contains yellow uitramarine, manufacture the striated colour filter with 4 chromatic colorant regions.That is, as shown in Fig. 5 (A), in ink-jet application for the first time, be colored as the first composition for ink of red (R) and blue (B), take homochromy line as W _av4* 4[W _av4the mean value as the live width of the painted areas of 4 looks of target; W _av4=(w _r+ w _g+ w _b+ w _w)/4] the mode of spacing, with R and alternately ejection simultaneously of B, irradiation ultraviolet radiation forms (UV1) by each painted filming with wire.Then, gap area to the linearity forming between painted the filming by the above-mentioned R being formed by the first composition for ink and B, as shown in Fig. 5 (B), ejection is colored as the second composition for ink of white (W) and green (G), irradiation ultraviolet radiation by each painted film form wire can (UV2).

The Production Example of the colour filter of situation as shown in Figures 4 and 5, comprising:

(1) by having used the ink-jetting style of a plurality of China ink heads, to (n+1) row, (n+3) row, (n+5) row ... the operation of the first composition for ink that the line region coating of such odd column contains ink-resistant composition and ultraviolet curing composition;

(2) irradiation ultraviolet radiation, solidifies above-mentioned (1) described composition for ink, forms the first painted operation of filming;

(3) utilize ink-jetting style, to n row, (n+2) row, (n+4) row ... the coating of line region and the first painted static contact angle θ filming of such even column _kbe 35 ° of second above and contain ultraviolet curing composition composition for ink operations; And

(4) irradiation ultraviolet radiation, solidifies the composition for ink that above-mentioned (3) are recorded, and forms the second painted painting membrane process;

Can be described as the manufacture method of the striated colour filter of the painted areas that forms striped style on support base material.It should be noted that, the order of the even column described in the odd column described in above-mentioned (1) operation and (3) operation can be also contrary.

[Production Example 1 of mosaic shape colour filter]

The fabrication schedule of the mosaic shape colour filter of the painted areas that Fig. 6 represents red (R), green (G), blue (B), white (W) this 4 look have formed grid style.First, in the ink-jet application of the 1st time shown in Fig. 6 (A), the imaginary grid of arranging with x-y direction on support base material (vertical d ₁* horizontal d ₁) in, to the cell subgroup (2d being formed by 4 grid ₁* 2d ₁) the ejection of upper right grid contain ink-resistant composition and ultraviolet curing composition and coordinate colouring agent and be colored as the first red composition for ink, irradiation ultraviolet radiation (UV1), forms and has the red colored of surperficial ink-resistant and film.In this wise, in an ink-jet application, with respect to the left and right above-below direction of grid, composition for ink is non-conterminous, thereby can form exactly the painted of regulation, films.Now, can be with 1 melted ink composition landfill target grid, also can be with 2 above composition for ink landfills.

Then, in the 2nd ink-jet application shown in Fig. 6 (B), the lower-left grid ejection of plaid matching subgroup contains ink-resistant composition and ultraviolet curing composition and cooperation colouring agent and is colored as the first green composition for ink, irradiation ultraviolet radiation (UV2), formation has the green coloring of surperficial ink-resistant and films.

Then, in the ink-jet application of the 3rd time as shown in Fig. 6 (C), the upper left grid ejection of cell subgroup is coordinated colouring agent and is colored as blue composition for ink, irradiation ultraviolet radiation (UV3), forms blue-colored filming.Now, by red colored the filming previously having obtained, filmed in the grid gap area that surrounds and form with green coloring, its up and down adjacent 4 grid there is the first painted encirclement of filming of surperficial ink-resistant, these painted filming can be talked about the such effect in next door (or matrix), if so blue ink composition and these painted static contact angle θ filming _kbe 35 ° above, preferably more than 40 °, from the blue ink composition of nozzle ejection, can not exceed this scope.

Similarly, in the 4th ink-jet application as shown in Fig. 6 (D), for the bottom right grid ejection of cell subgroup, containing coloring pigment, containing for the composition for ink (white) of transparent resin, at the red colored grid gap area of filming and filming and forming in encirclement mode with green coloring by previously having obtained, owing to surrounding its first painted filming around, play the such effect in next door (or matrix), if with these painted static contact angle θ filming _kbe 35 ° above, be preferably more than 40 °, from the white ink composition of nozzle ejection, just can not exceed this scope.That is, the composition for ink using in the ink-jet application of the 3rd time and the 4th, can be used and needn't take ink-resistant composition as the second essential composition for ink.Certainly, this second composition for ink also can contain ink-resistant composition.After coating white ink composition, irradiation ultraviolet radiation forms painted filming, and can obtain thus grid style and possess the mosaic shape colour filter in 4 chromatic colorant regions.It should be noted that, for example, replace color white to film non-colored section is set, using it as transparent pixels region, utilize, in electronic paper purposes, be fine.In addition, as shown in Figures 7 and 8, when ink-jet application the first composition for ink, painted number and a China ink number, can be a plurality of colors, also can use a plurality of black heads.In other words, in same ink-jet application number of times, the grid that coating condition is adjusted in x direction or the arrangement of y direction has been coated with after composition for ink, and on limit, pixel does not contact mutually.For example, can specifically be set forth in the situation of coating 3 looks, in the 1st when coating, is utilized the black head of each color, with in x direction or the separately coating of the non-touching mode of y direction, is using the method etc. in 3 look landfill gaps for the 2nd time.

The condition that ultraviolet ray is irradiated, before by each composition for ink ultraviolet curing, carry out as required heat drying, and on support base material, form after painted the filming of 4 looks and can carry out ultraviolet ray irradiation, the heat treated of whole, all identical with the Production Example situation of foregoing striated colour filter.In addition, when manufacturing mosaic shape colour filter, the first composition for ink preferably with the contact angle θ of support base material _lbe more than 3 °, when 3 ° of less thaies, be difficult to control wetting expanding area.In addition, the upper limit is preferably below 45 degree, if surpass 45 degree, when a plurality of drops are integrated, stained area is unstable.And the contact angle of the second composition for ink and support base material, between painted the filming being formed due to landfill, does not therefore limit its contact angle by the first composition for ink.In the situation that more paying attention to wetting expansion, preferred contact angle θ _lbe below 25 °.Comprise and confirm this contact angle θ _lmethod, confirm the second composition for ink and the first painted static contact angle θ filming _kmethod in content interior, that narrate in the Production Example of striated colour filter, applicable too when manufacturing this mosaic shape colour filter.

[Production Example 2 of mosaic shape colour filter]

In addition, Fig. 7 represents that red (R), green (G) and blue (B) this 3 look form the fabrication schedule of mosaic shape colour filter of the painted areas of grid style.In this embodiment, in primary ink-jet application, to by (x _n, y _n), (x _n+1, y _n), (x _n, y _n+1) and (x _n+1, y _n+1) in the cell subgroup a that forms of these 4 grid in grid (x _n, y _n) and grid (x _n+1, y _n+1) 2 grid of position relationship, spray respectively 4 and be colored as the first red composition for ink, by ultraviolet curing (UV1) induced surface ink-resistant, form red colored filming.Then, in grid (x _n, y _n+1) and grid (x _n+1, y _n+2) 2 grid of position relationship, spray respectively 4 and be colored as the first green composition for ink, by ultraviolet curing (UV2) induced surface ink-resistant, form green coloring and film.

By above-mentioned, grid (x for example _n, y _n+2) become 4 adjacent up and down grid and be colored as the red and green membrane-enclosed grid gap area of the first painted painting, in the 3rd ink-jet application, the static contact angle θ that ejection is red and green coloring is filmed with these _kbe 35 ° above, be preferably 40 ° and above be colored as the second blue composition for ink, irradiation ultraviolet radiation forms the second painted filming, and can obtain having the mosaic shape colour filter of 3 look grid styles.It should be noted that, as shown in Figure 7,4 residual non-colored section in painted angle part of filming of landfill grid, this non-colored section does not have special problem for the colour filter that is applicable to electronic paper etc.In addition, as mentioned above, in the 1st ink-jet application and the 2nd ink-jet application, the painted contact edge part of filming forming in grid, when the 3rd ink-jet application, these painted filming are played the effect of so-called next door, therefore the second composition for ink of ejection, because colour mixture does not occur the painted surperficial ink-resistant of filming previously forming yet, can reduce in addition painted overlapping, coloured part not of filming.In the coating process of all kinds of more than recording, stipulated the position relationship of painted grid, but painted order is not limited to above-mentioned record.

[Production Example 3 of mosaic shape colour filter]

In addition, Fig. 8 means other examples of fabrication schedule of mosaic shape colour filter of the painted areas of the grid style that forms red (R), green (G) and blue (B) this 3 look, in this example, by the 1st ink-jet application by 3 looks the first composition for ink separately with grid (x in cell subgroup a _n, y _n) and grid (x _n+1, y _n+1) position relationship ejection, irradiation ultraviolet radiation (UV1), forms 3 chromatic colorants and films.

Then, in the 2nd ink-jet application, as grid (x _n, y _n+1) and grid (x _n+1, y _n) like that, the grid gap area through the 1st ink-jet application formation being sprayed to 3 looks the second composition for ink separately, irradiation ultraviolet radiation (UV2) forms 3 chromatic colorants and films, to obtain mosaic shape colour filter.In this wise, painted 4 jiaos of filming of landfill grid do not contact, and painted film adjacent with 4 limits contacts, and can form the colour filter that non-colored section is few thus.In this case, as described above,

Through 1 ink-jet application, can be coated with a plurality of China ink heads of a plurality of colors simultaneously.
