588215 Printed by A7 B7, Consumer Cooperatives, Intellectual Property Bureau, Ministry of Economic Affairs 5. Description of the Invention (1) This invention relates to a novel red color photoresist ink for color filters (CF) for liquid crystal displays (LCD) and the use of this CF for ink LCD. BACKGROUND ART A coloring composition of a high molecular organic material using a red pigment diketopyrrolopyrrole (DK P P) is known. For example, it can be used as powder, paste, processing paste and blending agent, suitable for printing ink, color of material, color of adhesive or coating material (for example, Japanese Patent Publication No. 8-207 3 1 and Japanese Patent Application Laid-Open No. 8-273 9 1) Disclosure of the Invention However, a red color photoresist ink (RCR I) was prepared by using a dispersion of the DKPP pigment prepared by the conventional formula mentioned above, and the use of this ink to produce CF for LCDs has failed. The problem of achieving the high level of high-quality chroma required by the recent high-grade CDs still exists. This is due to the large primary particle size of the conventional DKPP system and its difficulty in dispersing. In addition, DKPP has a large crystal growth property at a high temperature of more than 250 t, and is exposed to a still-temperature CF application at a temperature of more than 250 ° C in the sputtering process of I but 〇, because of the d KPP pigment. Crystal growth and crystal precipitation on the CF surface may cause haze, which is a problem. The purpose of the present invention is to provide the standard of Chinese paper (CNS) a4 size < 210x297 mm when used in LCD CF. (Please read the precautions on the back before filling this page} -4- 588215 A7 B7 V. Description of the invention (2) The RCRI mentioned above and which can give a high level of chroma. The present inventors and others are DKPP to date which has been used as a red pigment for RCRI 4, 4 / Compared with monodiamino-1, 1 / di-anthraquinone (DABAQ), it focuses on the characteristics of a larger upright tendency that appears near 5 50 ~ 600 nm with a spectral transmission curve. If it is adopted, this DKPP has been applied. When RCRI is used as a red pigment, the area of overlap with the isochromatic function y (λ) is large, that is, the brightness Y 値 can be significantly improved compared to conventional LCD CFs. Furthermore, by using DKPP's micronization treatment, As a red pigment, it is anticipated that the increasing tendency of Y 値 can be accelerated and researched. However, DKPP is a problem that the dispersibility and dispersion stability are inferior to conventional pigments, and the crystal growth at high temperature and become the surface of CF. The conflict of issues caused by the foggy situation, This has become a hindrance to the development of high-brightness photoresist inks. Therefore, the present inventors reviewed the dispersion conditions of DKPP pigments and found that it is possible to suppress the difficulty of dispersibility when the pigments are dispersed and the crystal growth when CF is exposed to high temperatures. Pigment dispersion conditions, so that the present invention is completed. That is, the present invention is a red color photoresist ink obtained by dispersing a red pigment in a photosensitive resin composition, and subjected to a surface treatment with a diketopyrrolopyrrolesulfonic acid derivative. Surface-treated diketopyrrolopyrrole pigment (A), in (a) poly (lower alkyleneimine) or (b) polyallylamine, with (i) a polymer having a free carboxylic acid group Esters, (i) polyamines having free carboxylic acid groups and (iii) one or more selected from polyester amines having free carboxylic acid groups to react and form amines or salts to form graft polymers (B), a red color photoresist that is characterized by a dispersant to disperse.

Order the Ministry of Economy Printed by the Consumers 'Cooperative of the Property Bureau-5- 588215 Printed by the Consumers' Cooperative of the Bureau of Wisdom and Finance of the Ministry of Economic Affairs. The red color photoresist ink is prepared by using a diketopyrrolopyrrole sulfonic acid derivative (E) in the crystal growth inhibitor and / or dispersant, and using the graft polymer (B) in the dispersant. The diketopyrrolopyrrole pigment is dispersed and becomes a characteristic red color photoresist ink. Furthermore, the present invention is a color filter manufactured by using the aforementioned red color ink. Hereinafter, the present invention will be described in detail. The surface-treated DKP P pigment (A) and D K P P pigment (D) used in the present invention can be produced, for example, as follows. First, DKPP pigment (D) can be synthesized by reacting p-chlorobenzonitrile with bromoacetate in the presence of zinc powder. Second, surface treatment DKP P pigment (A) is a solution of DKPP pigment (D) in concentrated sulfuric acid. Fuming sulfuric acid, chlorosulfonic acid or a mixed liquid oil thereof is heated to 8 2-9 ° C and subjected to a sulfonation reaction. The suspension obtained by diluting with a large amount of water is filtered, washed with water, and dried. The filter cake was filtered to obtain a diketopyrrolopyrrole sulfonic acid derivative (DKPPS). Secondly, DKPP and DKPPS were dissolved in concentrated sulfuric acid of the solvent, and then poured into water to precipitate. Dried and crushed, DKPP can be treated by DKPPS surface treatment DKPP. However, it is not limited by the above method. Here, the above DKPPS is based on the following general formula (1) This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -6- 588215 A7 B7 V.

(However, in the formula, X represents hydrogen or halogen, and m, η is m + n = l ~ 4.) Printed and displayed by the Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs. The surface-treated DKPP (A) is compared with general DKPP, and it can be estimated as follows in a mechanism having superior dispersibility or dispersion stability. That is, because DKPPS used for surface treatment has the same molecular backbone as DKPP, the mixed sulfuric acid solution of the two is put into water and precipitated out. DKPP S system can be pre-adsorbed on the surface of DKPP and formed. Surface treatment status. At this time, the hydrophilic sulfonic acid group emerges from the combined surface and increases the negative surface potential of the surface of the DKPP pigment, which contributes to the increase in pigment dispersibility and dispersion stability caused by the static rebound force 3, In addition, DKP PS is caused by the aforementioned negative potential to increase the adsorption and adsorption strength of a polymer dispersant having a cationic anchor (anchor) portion such as an amine group, which will be described later, and also caused by the dispersant. The three-dimensional rebound force is increased and it is considered to be capable of exerting a function as a dispersing auxiliary agent for increasing the dispersibility and dispersion stability of the pigment. In addition, although the surface treatments DKPP (A) and D K P P S (D) used in the present invention use this surface area to form particulate matter having a size of 90 m 2 / g or more, it is more preferable to increase the point of brightness Y 値. This microparticulate matter is applicable to a so-called flushing method in which the aforementioned water-containing filter cake and the vehicle are mixed and the agitation is continued from the aqueous phase to the vehicle phase by continued vigorous stirring. As for the color-developing agent used here, we can cite the interface activity.

As a method for producing the particulate matter, a salt milling method in which DK P P is surface-treated by honing and crushing in the presence of common salt can also be mentioned. The method for producing the fine particles is not particularly limited. Furthermore, the surface treatments DKPP (A) and DKPP (D) used in the present invention are made of DKPP, which has been purified by washing with an organic solvent and has been removed from impurities, and the maker of the sulfonic acid derivative thereof; The problem of crystal precipitation or discoloration is more suitable. Examples of the impurities include organic materials such as residues of raw material materials used in the production of DKPP, such as 4-chlorobenzonitrile. Therefore, the organic solvent used for washing DKPP is not particularly limited as long as it dissolves the above impurities and does not dissolve diketopyrrolopyrrole, and examples thereof include aromatic solvents such as toluene, xylene, and methyl ethyl. Ketone-based solvents such as methyl ketone and methyl isobutyl ketone. The red color photoresist ink of the present invention is made by processing a D K P P pigment (A) or a D K P P pigment (D), a photosensitive resin composition and a dispersant on the surface of a red pigment. The pigment dispersion using the surface-treated D K P P pigment (A) has a dispersibility caused by the aforementioned electrostatic repulsive force, but uses a graft polymer as a dispersant for the purpose of imparting a three-dimensional rebound effect. As for the graft polymer (B) of this dispersant, it is a cross-linking agent which is adsorbed on the pigment, has a cationic group portion that achieves an anchoring function, and a polymer chain portion that is imparted with dispersibility by a three-dimensional rebound effect.

In addition, (a) to (b) or (i) to (ffi) may be used alone, or two or more kinds may be used on the other hand. Here, (a) to (b) are cationic radicals that achieve anchoring, and (i) to (iii) are high molecular chain moieties that impart dispersibility by a three-dimensional rebound effect. Therefore, the amount of amine groups in (a) to (b) and the molecular weight in (i) to (iii) become the dispersion and stability of the left and right pigments. The indicator of the performance of this dispersant is the amine value of the dispersant. The amine value of the cationic polymer dispersant used in the present invention is preferably in the range of 5 to 60 [KOHmg / g], and more preferably The range is 5 to 40 [KOHmg / g]. The decrease in the amine value indicates that the amount of amine groups in (a) ~ (b) needs to be reduced, or the molecular weight of (i) ~ (iii) needs to be increased. At this time, the adsorption of the pigment will be disadvantageous. However, It is advantageous for the three-dimensional rebound effect.

The total amount of 100 weight points of the invention description (10) points and (B) dispersant components, etc., should be in the range of 30 to 45 weight points. When this range is small, the high viscosity of the pigment dispersion also increases the viscosity when the diameter is increased, and it is easy to become unsuitable. If the blending amount is smaller than this range, the effect of suppressing the crystal growth during high temperature exposure of CF becomes insufficient. And easily become discomfort. When the blending amount is more than this range, the dispersibility becomes poor, and agglomerated particles occur on the coated surface of the photoresist ink, making it easy to become uncomfortable. Therefore, (A) > (D) is calculated as the pigment component, (C), (E) is calculated as the dispersant component, but (B) is excluded from the calculation. (C) is a crystal growth inhibitor, but it is also called a dispersing assistant because it also acts as a dispersing assistant for (B). Similarly, (E) is a dispersant, but it also acts as a dispersing aid or crystal growth inhibitor for (B), so it is called a dispersing aid or crystal growth inhibitor. In the RCRI of the present invention, as for the method of dispersing the red pigment (a) surface-treated DKPP pigment or (D) DKPP pigment in a photosensitive resin, the pigment is dispersed in advance in a graft polymer (B) in which a dispersant is dispersed.
