Description

  The present invention relates to a dye-containing colored curable composition suitable for forming a color filter used in a liquid crystal display device or a solid-state imaging device, a dye-containing color filter, and a method for producing the same.

  As a color filter formed on a device for colorizing a solid-state imaging device or a liquid crystal display device, a yellow filter layer, a magenta filter layer, and a cyan filter layer formed adjacent to each other on the same plane of the substrate Known color filters include color filters, red filter layers, green filter layers, and blue filter layers. A band-like pattern or a mosaic pattern is formed by these filter layers.

  Various methods have been proposed so far for producing the color filter as described above. In particular, a so-called color resist method in which a photosensitive resin composition containing a dye is exposed and developed to repeatedly perform a patterning process a required number of times has been widely put into practical use.

  The color resist method is a method for producing a color filter by a photolithographic method using a colored radiation-sensitive composition in which pigments are dispersed in various photosensitive compositions. This method uses pigments. It is stable to light, heat, and the like, and has a sufficient positional accuracy because it is patterned by a photolithography method, and is a suitable method for manufacturing a color filter for a large screen and a high-definition color display.

  When a color filter is produced by a pigment dispersion method in which a pigment is dispersed as described above, a coating film is formed by applying a radiation sensitive composition on a glass substrate using a spin coater or a roll coater. A colored pixel is obtained by pattern exposure and development, and a color filter is obtained by performing this operation in accordance with a desired number of hues. As a pigment dispersion method, a negative photosensitive composition using a photopolymerizable monomer and a photopolymerization initiator in an alkali-soluble resin is known. (For example, see Patent Documents 1 to 8 and 12.)

  However, in recent years, further enhancement in definition has been desired for color filters for solid-state imaging devices. However, the conventional pigment dispersion system as described above does not improve the resolution, and also has problems such as color unevenness due to coarse pigment particles. Was not suitable for applications that required

Conventionally, the use of dyes has been proposed for such problems (see, for example, Patent Documents 9 to 11).
On the other hand, it is known that a mixture of a violet dye and a cyan dye is used for a blue filter array of a color filter (see, for example, Patent Document 12).
Japanese Patent Laid-Open No. 1-102469 Japanese Patent Laid-Open No. 1-152499 JP-A-2-181704 JP-A-2-199403 Japanese Patent Laid-Open No. 4-76062 Japanese Patent Laid-Open No. 5-273411 JP-A-6-184482 JP-A-7-140654 JP-A-6-75375 JP 2002-14221 A Japanese Patent Publication No.7-111485 Japanese Patent Laid-Open No. 2002-14222

However, the dye-containing curable composition has the following problems, and further improvement has been demanded. That is,
(1) Dyes are generally inferior in heat resistance, light resistance and the like as compared with pigments, and have insufficient fastness.
(2) When the molar absorption light coefficient of the dye is low, a large amount of dye must be added. In this case, other compounds such as a polymerizable compound, a binder and a photopolymerization initiator in the curable composition The components must be relatively reduced, and the curability at the time of curing the composition, the heat resistance of the cured portion that has been cured, the developability of the non-cured portion, and the like are reduced.
(3) The dye often exhibits an interaction with other components in the curable composition, and it is difficult to adjust the developability (solubility) of the cured part and the non-cured part.
As described above, the dyes conventionally used in the photosensitive composition are not particularly satisfactory in fastness, and further have low solubility in the photosensitive composition and contain the dye at a high concentration. It was also difficult.

  In addition, as described above, the dye forming the mixture used in the blue filter array is insufficient in heat resistance and light resistance, and further improvement is desired.

  The present invention has been made in view of the above, and has excellent hue (molar extinction coefficient and color value) and vividness, and is excellent in light resistance, heat resistance, and pattern formation (developability). Composition, sharp color pattern (especially rectangular with good cross-sectional shape), high resolution, good hue, light resistance and heat resistance, and development residue in uncured areas can be prevented An object of the present invention is to provide a color filter manufacturing method capable of producing the color filter with high productivity (high cost performance), and to achieve the object.

  In the present invention, various dye compound derivatives having a good hue and high fastness to light and heat have been examined in detail. The dye having a specific structure particularly has fastness such as heat resistance and light resistance. Based on this knowledge, a colored curable composition, a color filter, and a method for producing the same were provided, and the above object was achieved.
