Description
Technical field
The present invention relates to the colored filter of colored filter (color filter) with coloured composition and use said composition.
Background technology
Colored filter is, and is parallel or dispose the optical filter joint (filter segment) of the fine band shape of different form and aspect more than 2 kinds across on the surface of transparency carriers such as glass, perhaps constitutes with the fine optical filter joint of certain alignment arrangements.The optical filter joint is number μ m～hundreds of μ m, and each form and aspect fitly is configured on the substrate with predetermined arrangement.
Usually, in the color liquid crystal display arrangement, by evaporation or sputter, form on colored filter and drive the transparency electrode that liquid crystal is used, further forming thereon and making liquid crystal aligning is the alignment film that certain orientation is used.In order to give full play to the performance of these transparency electrodes and alignment film,, preferably under the high temperature more than 230 ℃, form transparency electrode and alignment film usually more than 200 ℃.Therefore, now in the manufacturing method of color filters, the pigment dispersing method that the composition that the pigment dispersing of photostability, excellent heat resistance is formed in pigment carrier forms colored filter becomes main flow.
On the other hand, not only requiring to improve color characteristics for colored filter in recent years is lightness or colour purity, and the requirement of the coating homogeneity when forming colored filter, sensitivity, development, pattern form etc. is also improving.Particularly, for the solid-state imager optical filter that uses in video camera or digital camera, the electron colour scanner (co1orscanner) etc., require that height becomes more meticulous, high brightnessization, high colorrendering quality.Here, become more meticulous,, can not realize that then height becomes more meticulous if sneak into the foreign matter of several μ m in the optical filter joint about height.In addition, the signal with mistake when sneaking into foreign matter is sent to imaging apparatus, becomes the bad reason of imaging apparatus.The reason of foreign matter mainly is to result from the offspring of pigment, at present, improve the dispersing of pigments degree, reduce offspring with mechanical means, perhaps colored filter is filtered with coloured composition, can prevent sneaking into of foreign matter by filtrator with suitable aperture.
But pigment excessively disperses, exist pigment from offspring when primary particle disperses, the situation of primary particle fragmentation.Primary particle or the pigment that has carried out the offspring miniaturization, when excessively carrying out miniaturization, there is the problem that forms huge block pigment solid matter in aggegation easily usually.In addition, the pigment that will carry out miniaturization disperses in the pigment carrier that contains resin etc., makes its not aggegation become offspring, but with in stable conditionization near primary particle, is very difficult.
In addition, with primary particle or carried out the coloured composition that the pigment dispersing of offspring miniaturization forms in pigment carrier, along with time pigment particles aggegation often, produce corase particles, high viscosityization shows thixotropy.The viscosity of such coloured composition rises, poor flow quality, will cause problem in the manufacturing operation and the variety of issue on the value of the product.For example, poor flow quality will worsen the wetting state for filtrator, become the slack-off reason of filter velocity.
In order to disperse to have the organic pigment of phthalocyanine structure, patent documentation 1～2 proposes, to be precursor skeleton and be the method that substituent pigment derivative is mixed as spreading agent with the organic pigment with acidic-group or basic group, but in the colored filter purposes that requires the height pigment dispersing, do not obtain sufficient adaptability.
