Description

Coloring composition, film, optical filter, solid-state imaging element and image display device The present invention relates to a coloring composition comprising a coloring agent. In addition, the present invention relates to a film, an optical filter, a solid-state imaging element, and an image display device using the coloring composition. Recently, due to the widespread adoption of digital cameras and mobile phones equipped with cameras, the 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 devices. Color filters typically have pixels of the three primary colors—red, green, and blue—and play the role of decomposing transmitted light into the three primary colors. Each colored pixel of a color filter is manufactured using a coloring composition containing a coloring agent. Patent Document 1 describes forming a pixel of a color filter using a coloring composition containing a pigment comprising an azomethan metal complex pigment, a pigment derivative in which two sulfonic acid groups are introduced to the azomethan metal complex pigment, a resin, and a solvent. The contents of the present invention will be described in detail below. In this specification, "~" is used to mean including the values listed before and after it as lower and upper limits. In the notation of groups (atomic groups) in this specification, notations that do not specify substitution or non-substitution include groups (atomic groups) that have substituents along with groups (atomic groups) that do not have substituents. For example, "alkyl group" includes not only alkyl groups that do not have substituents (non-substituted alkyl groups) but also alkyl groups that have substituents (substituted alkyl groups). In this specification, the term "exposure" includes not only exposure using light but also drawing using particle beams such as electron beams and ion beams, unless specifically explained otherwise. In addition, light used for exposure may include active light or radiation such as emission spectra of mercury lamps, far ultraviolet light represented by excimer lasers, extreme ultraviolet light (EUV light), X-rays, and electron beams. In this specification, "(meth)acrylate" represents either acrylate or methacrylate, "(meth)acryl" represents either acrylic or methacryl, and "(meth)acryloyl" represents either acryloyl or methacryloyl. In the present specification, Me represents a methyl group, Et represents an ethyl group, Bu represents a butyl group, and Ph represents a phenyl group in the structural formula. In this specification, the weight average molecular weight and the number average molecular weight are polystyrene equivalent values measured by the GPC (gel permeation chromatography) method. In this specification, total solid content refers to the total mass of the components excluding the solvent from the total components of the composition. In this specification, the term "pigment" refers to a compound that is difficult to dissolve in a solvent. In this specification, the term "process" includes not only independent processes but also cases where the process cannot be clearly distinguished from other processes, provided that the intended function of the process is achieved. Coloring composition The coloring composition of the present invention is a coloring composition comprising a coloring agent and a resin, wherein the coloring agent comprises a compound Y in which a compound represented by formula (1) is coordinated to a metal atom, and the content of the compound Y in the total solid content of the coloring composition is 1 mass% or more and less than 10 mass%. According to the coloring composition of the present invention, a film with excellent moisture and heat resistance can be formed. Although the detailed reason for obtaining such an effect is unclear, it is presumed that since compound Y has appropriate hydrophobicity, the interactions between compounds Y are not disrupted by water even when water penetrates the film, and the associative state is maintained. The coloring composition of the present invention is preferably used as a coloring composition for a color filter or an infrared transmission filter. More specifically, it can be preferably used as a coloring composition for forming pixels of a color filter or as a coloring composition for forming an infrared transmission filter, and is more preferably used as a coloring composition for forming pixels of a color filter. Examples of pixel types include red pixels, green pixels, blue pixels, magenta pixels, cyan pixels, yellow pixels, etc., and it is preferable that the pixels be red pixels, green pixels, or yellow pixels, more preferable that the pixels be red pixels or green pixels, and even more preferable that the pixels be green pixels.
