Abstract
To provide a radiation-sensitive composition for a color filter with which a red pixel having high transmittance and a contrast ratio can be formed, the composition having rheological characteristics suitable for coating a large substrate. The radiation-sensitive composition contains: (A) a pigment; (B) a dispersant; (C) a copolymer of (c1) a carboxyl group-containing unsaturated monomer comprising an (meth)acrylic acid, (c2) N-site substituted maleimide, and (c3) at least one kind of copolymerizable unsaturated monomer selected from a group consisting of polystyrene macromonomers and polymethylmethacrylate macromonomers; (D) a polyfunctional monomer; (E) a radiation-sensitive radical generating agent; and (f) a solvent. The pigment (A) contains C.I.Pigment Red 242 by >=20 wt.% and the average particle size r (nm) of the pigment (A) is in the range of 50<=r<=200.
Description
Technical field
The present invention relates to be used for the radiation-sensitive composition of color filter, its preparation method, color filter and color liquid crystal display arrangement.More specifically, relate to the radiation-sensitive composition that is used for color filter, said composition can be used for being manufactured on employed color filter in transmission-type and Reflexible color LCD and the coloured image camera head, also relate to its preparation method, have the color filter of the red pixel of forming by the radiation-sensitive composition that is used for color filter, and the color liquid crystal display arrangement with this color filter.
Background technology
As the method for making color filter with colored radiation-sensitive composition, known method is, in substrate or comprising the coating that forms colored radiation-sensitive composition in the substrate of light shield layer with desired pattern, carry out radiation (being referred to as " exposure " hereinafter) by mask with desired pattern, utilize alkaline developer to develop, so that dissolving is also disposed unexposed portion, and in clean baking oven or after on the heating plate, cure, thereby obtain colour element (with reference to JP-A2-144502 and JP-A3-53201) (term as used herein " JP-A " is " unexamined; disclosed Japanese patent application ").
Therefore because expectation comprises that the liquid crystal indicator of color filter has high brightness, the demand to color filter with high-transmission rate increases.In order to satisfy this demand,, be known that the combination with C.I. paratonere 254 and C.I. paratonere 242 is effective especially as the pigment that is used to form red pixel as disclosed in JP-A 2002-372618.
Along with the immediate development of digital camera and high-definition television, to can show heavy colour for example the needs of the color liquid crystal display arrangement of mazarine sea in winter or the cerise setting sun increase.If " blackness " of black display part do not clearly illustrate out, then will obtain unsharp blurred picture.The pixel or the color layer that therefore, need have high colouring intensity and hard contrast ratio.
Along with liquid crystal indicator is done increasingly dimensionally, the substrate of glass that is used to make color filter is also done increasingly dimensionally.Be known that when substrate being done dimensionally when big, be difficult on the whole surface of substrate and form uniform coat film.The typical coating technique that is used for the radiation-sensitive composition of color filter comprises center drippage cladding process, slit spin coating method and slot coated method.Have been found that when utilizing these coating techniques the rheology of coating solution self can influence coating efficiency greatly.Though with regard to coating efficiency, the expectation rheology of solution is newton's solution, when the dispersion efficiency of pigment dispersion hanged down, the dispersion that obtains trended towards becoming non newtonian solution.In this case, utilize the coating technique of control film thickness by rotation, for example cladding process and slit spin coating method are dripped in the center, will have the difference of film thickness between the core of substrate and end portion.Even utilize the slot coated technology that does not have rotation, also can make transmission and homogenize characteristic become even worse, cause breakdown of coating thus, for example inhomogeneous the or formation striped on the film thickness.Thus, wish that the radiation-sensitive composition that is used for color filter has the rheological properties that approaches newton's solution.
Summary of the invention
An object of the present invention is to provide a kind of radiation-sensitive composition that is used for color filter, this radiation-sensitive composition provides the red pixel with high-transmission rate and hard contrast ratio, and has the rheological properties that is suitable for the large-sized substrates application.
Another object of the present invention provides a kind of preparation method who is used for the radiation-sensitive composition of color filter of the present invention.
Another purpose of the present invention provides a kind of color filter relevant with the preparation method of the radiation-sensitive composition that is used for color filter of the present invention and the color liquid crystal display arrangement with this color filter.
