preparation example Construction

[0126] The preparation conditions of the organic material solution are not particularly limited, and can be selected from a temperature equal to or less than the boiling point of the solvent at normal pressure to subcritical and supercritical conditions of the solvent. The temperature under normal pressure is preferably -10 to 150°C, more preferably -5 to 130°C, particularly preferably 0 to 100°C.

[0127] In the present invention, the organic material must be uniformly dissolved in a good solvent, but the dissolution is preferably performed under acidic or basic conditions. Generally, alkaline conditions are used when pigments with groups that can be dissociated under basic conditions are used in the molecule, and when there are no groups that dissociate under basic conditions and there are a large number of nitrogen atoms in the molecule that are easy to add protons Use acidic conditions. For example, quinacridone compound pigments, diketopyrrolopyrrole compound pigments, a...

[0616] Hereinafter, the present invention will be described in more detail based on examples, but the present invention is not limited to these examples.

Embodiment 1

[0619]

[0620] In 1000ml of dimethyl sulfoxide (manufactured by Wako Pure Chemical Industries, Ltd.), add 33.3ml of sodium methoxide 28% methanol solution, 50g of pigment C.I. pigment red 254 (Irgaphor Red BT-CF, trade name, Chiba Specialty Chemicals Co., Ltd.) and 100.0 g of polyvinylpyrrolidone (K-30, trade name, manufactured by Wako Pure Chemical Industries, Ltd.), to prepare a pigment solution A. Separately, 1000 ml of water containing 16 ml of 1 mol / l hydrochloric acid (manufactured by Wako Pure Chemical Industries, Ltd.) was prepared as a poor solvent.

[0621] At this time, the temperature was controlled at 18° C., and in 1000 ml of poor solvent—water 1,000 ml stirred at a speed of 500 rpm by using GK-0222-10 Ramond star-ra- (trade name, manufactured by Fujisawa Pharmaceutical Co., Ltd.), - KX-500 large-capacity non-pulsation pump (trade name, manufactured by Nippon Seiko Chemical Co., Ltd.) injects 100 ml of pigment solution A at a flow rate of 100 ml / min to form or...

Abstract

Provided are an organic nano-particle which has nano-size and its particle distribution is sharp; and an organic nano-particle dispersion composition having stable and excellent dispersion property, flow behavior. Besides, provided are a color filter made of them, which has high contrast and perform excellent display property; a liquid crystal device and a CCD device by using them; and a colored photosensitive resin composition and a photosensitive resin transcription material by using them. An organic nano-particle which is consisting of organic material, its amount average particle size is 50 nm or less, and the ratio of (volume average particle size) / (amount average particle size) is 1.0~2.0.

Description

technical field [0001] The present invention relates to organic nanoparticles formed by a reprecipitation method and dispersion compositions thereof; in addition, the present invention also relates to colored photosensitive resin compositions and photosensitive resin transfer materials containing them, as well as materials with bright hues formed by them. , high tinting strength and high contrast color filters, liquid crystal display devices and CCD devices. Background technique [0002] Pigments have vivid hues, high tinting strength, light fastness, etc., and are widely used in many fields. Among these pigments, fine particles are usually mostly practically important. This is an attempt to obtain vivid hues and high tinting strength through micronizing treatment to prevent pigment aggregation. However, if the pigment is micronized by a physical method such as salt milling, the pigment dispersion tends to exhibit high viscosity. Therefore, when the pigment dispersion is ...
