Description

Color composition for color filter and color filter
Technical field
The present invention relates to employed color composition for color filter and the color filter with the filter section that uses its formation in the manufacturing of color filter, this color filter is used for color liquid crystal display arrangement, colour pick-up tube element etc.
Background technology
In recent years, liquid crystal indicator is slim owing to it, therefore is be evaluated as to have saving spatiality, lightweight and save electric power etc., recently, is popularized rapidly in the TV purposes.In the TV purposes, require further to improve performances such as brightness and contrast, in the color filter as the parts that constitute the color liquid crystal device, also expectation further improves transmissivity, improves contrast etc.
As the method for making of color filter, known have a following method: after utilizing photoresist to form pattern, with the decoration method of pattern-dyed; Be pre-formed the transparency electrode of predetermined pattern, form the electrodeposition process of pattern by the resin ionization that contains pigment that applies voltage and will in solvent, dissolve, disperse; Use contains the print process that the printing ink of heat reactive resin or ultraviolet curable resin for example carries out hectographic printing; Use is dispersed in colorants such as pigment the pigment dispersing method of the colored anticorrosive additive material that forms in the photo anti-corrosion agent material etc.Recently, the pigment dispersing method becomes main flow.Yet, use pigment as the color filter of colorant because the light scattering that pigment particles produces etc., the polarized light degree by liquid crystal control takes place chaotic, consequently, the problem that exists the brightness that causes color liquid crystal display arrangement easily or contrast to reduce.
As the technology that addresses this problem, proposed to contain the colored anticorrosive additive material of dyestuff as colorant.Yet, for the dyestuff that uses in the color filter, require heat-resisting and photostability and with the compatibility and the dissolubility in the organic solvent of this resin of dissolving of the resin that constitutes color filter.For example, the colored anticorrosive additive material that mixed dye forms in hardening resin composition is disclosed for Japanese kokai publication hei 6-75375 number.Yet therefore this colour anticorrosive additive material has been to use the material of the low dyestuff of thermotolerance owing to can carry out the back baking under lower temperature, is not the material that makes the raisings such as thermotolerance of dyestuff self.
Therefore, in order to increase dissolubility and to improve thermotolerance and photostability, proposed to use the color filter of the salt of anionic property dyestuff and cationic compound as colorant.For example, in TOHKEMY 5-333207 number, disclose the one-tenth salt dyestuff that anionic dye is obtained with alkylammonium, alkanol ammonium or cyclohexyl ammonium formation salt, in TOHKEMY 2004-307391 number, disclose the one-tenth salt dyestuff that anionic dye is obtained with naphthyl ammonium formation salt.Yet, these become salt dyestuffs to the dissolubility of the solvent that uses when making color filter not enough, also relatively poor with the compatibility of adhesive resin, therefore be difficult to provide the long preservation stability of color composition for color filter and film and transparency carrier such as glass between firm adaptation.
In addition, the crystallinity water-based coloured material that anionic dye is obtained with cationic polymer formation salt is for example disclosed in TOHKEMY 2005-350648 number.Yet this crystallinity water-based coloured material aspect the color filter purposes that requires to use, does not carry out detailed research in order to use and to be used with particle state under dissolved state.
On the other hand, for example in TOHKEMY 2000-352819 number, proposed in the copolymer solution that will have the monomer copolymerization of amide structure and obtain, to add the colored resin composition that the anionic property dyestuff forms.It works as the colored spots with the anionic property dyestuff by making amide structure, can make the dyestuff stabilization in filming, and improves tolerance.Therefore yet in the disclosed method, multipolymer mixes in organic solvent with anionic dye therein, exists the high dyestuff of polarity fully to dissolve and produces the such problem of foreign matter.
