Description

The present invention relates to a colored composition containing a pigment. The present invention also relates to a film using a colored composition, a red pixel, a color filter, a solid-state image sensor, and an image display device. The invention also relates to a kit.

In recent years, with the spread of digital cameras, camera-equipped mobile phones, and the like, demand for solid-state imaging devices such as charge-coupled device (CCD) image sensors has increased significantly. Color filters are used as key devices for displays and optical elements. A color filter usually includes pixels of three primary colors, red, green, and blue, and serves to separate transmitted light into the three primary colors.

Colored pixels of each color of the color filter are manufactured using a coloring composition containing a coloring material such as a pigment. In addition, a diketopyrrolopyrrole pigment or the like is used as a red pigment in a colored composition for forming a red pixel. For example, Patent Document 1 describes that a red pixel is formed using a coloring composition containing a red pigment such as Color Index Pigment Red 272 as a diketopyrrolopyrrole pigment.

It is also preferable to use Examples of such a container include the container described in JP-A No. 2015-123351.

<Method for preparing colored composition>
A colored composition can be prepared by mixing the aforementioned components. When preparing a colored composition, the colored composition may be prepared by dissolving and/or dispersing all components in a solvent at the same time, or, if necessary, each component may be prepared as two or more solutions or dispersions as appropriate. A colored composition may be prepared by mixing these at the time of use (at the time of application).

Moreover, it is preferable to include a process of dispersing pigments when preparing the colored composition. In the process of dispersing pigments, mechanical forces used for dispersing pigments include compression, squeezing, impact, shearing, cavitation, and the like. Specific examples of these processes include bead mills, sand mills, roll mills, ball mills, paint shakers, microfluidizers, high speed impellers, sand grinders, flow jet mixers, high pressure wet atomization, ultrasonic dispersion, and the like. In addition, when pulverizing pigments in a sand mill (bead mill), it is preferable to use small-diameter beads or increase the filling rate of the beads, thereby increasing the pulverizing efficiency. Further, it is preferable to remove coarse particles by filtration, centrifugation, etc. after the pulverization treatment. In addition, the process and dispersion machine for dispersing pigments are described in ``Complete Works of Dispersion Technology, Published by Information Technology Corporation, July 15, 2005'' and ``Dispersion technology centered on suspension (solid/liquid dispersion system) and industrial The process and dispersion machine described in Paragraph No. 0022 of JP-A No. 2015-157893, "Actual Application Comprehensive Data Collection, Published by Management Development Center Publishing Department, October 10, 1978" can be suitably used. Further, in the process of dispersing the pigment, the particles may be made finer in a salt milling step. For the materials, equipment, processing conditions, etc. used in the salt milling process, the descriptions in JP-A No. 2015-194521 and JP-A No. 2012-046629 can be referred to, for example.

In preparing the colored composition, it is preferable to filter the colored composition for the purpose of removing foreign substances and reducing defects. As the filter, any filter that has been conventionally used for filtration and the like can be used without particular limitation. For example, fluororesins such as polytetrafluoroethylene (PTFE) and polyvinylidene fluoride (PVDF), polyamide resins such as nylon (for example, nylon-6, nylon-6,6), and polyolefin resins such as polyethylene and polypropylene (PP) Examples include filters using materials such as high-density, ultra-high molecular weight polyolefin resins. Among these materials, polypropylene (including high-density polypropylene) and nylon are preferred.

The pore diameter of the filter is preferably 0.01 to 7.0 μm, more preferably 0.01 to 3.0 μm, and even more preferably 0.05 to 0.5 μm. If the pore diameter of the filter is within the above range, fine foreign matter can be removed more reliably. Regarding the pore size value of the filter, reference can be made to the nominal value of the filter manufacturer. As the filter, various filters provided by Nippon Pole Co., Ltd. (DFA4201NXEY, DFA4201NAEY, DFA4201J006P, etc.), Advantech Toyo Co., Ltd., Nippon Entegris Co., Ltd. (formerly Nippon Microlith Co., Ltd.), Kitz Microfilter Co., Ltd., etc. can be used. .

Moreover, it is also preferable to use a fibrous filter medium as the filter. Examples of fibrous filter media include polypropylene fibers, nylon fibers, and glass fibers. Commercially available products include the SBP type series (SBP008, etc.), the TPR type series (TPR002, TPR005, etc.), and the SHPX type series (SHPX003, etc.) manufactured by Loki Techno. When using filters, different filters (eg, a first filter and a second filter, etc.) may be combined. At that time, filtration with each filter may be performed only once, or may be performed two or more times. Further, filters having different pore diameters within the above-mentioned range may be combined. Alternatively, only the dispersion liquid may be filtered with the first filter, and then filtered with the second filter after other components are mixed. Further, a filter can be appropriately selected depending on the hydrophilicity and hydrophobicity of the composition.

It can be manufactured through the process of

(Photolithography method)
First, a case will be described in which pixels are formed by forming a pattern using a photolithography method. Pattern formation by the photolithography method includes a step of coating the above-mentioned colored composition of the present invention on a support to form a colored composition layer, a step of exposing the colored composition layer to light in a pattern, and a step of exposing the colored composition layer to light after exposure. It is preferable to include a step of developing and removing an unexposed area of the colored composition layer. Each step will be explained below.

In the step of forming a colored composition layer, a colored composition is applied onto a support to form a colored composition layer. The support is not particularly limited and can be appropriately selected depending on the application. For example, a glass substrate, a silicon substrate, etc. may be mentioned, and a silicon substrate is preferable. Further, a charge coupled device (CCD), a complementary metal oxide semiconductor (CMOS), a transparent conductive film, etc. may be formed on the silicon substrate.

The surface contact angle of the underlayer is preferably 20 to 70° when measured with diiodomethane. Further, it is preferable that the angle is 30 to 80° when measured with water. If the surface contact angle of the base layer is within the above range, the coating properties of the colored composition will be good.
