Provided is a colorant dispersion liquid that enables the formation of a coating film having an excellent heat tolerance and high brightness while adjusting the film color to a desired tone. The colorant dispersion liquid comprises a colorant (A), a dispersant (B) an a solvent (C), wherein the colorant (A) contains at least a colorant (A-1) in which a cation represented by general formula (I) forms a salt together with a monovalent anion represented by general formula (II). [In general formulae (I) and (II), the meaning of each symbol is as defined in the description.]

The present invention addresses the problem of providing a coating composition and an electro-conductive film, capable of improving touch panel performance, such as operational stability over time andtouch detection sensitivity of a liquid crystal display panel having a reduced thickness. This problem is solved by a coating composition comprising chain-like electro-conductive inorganic particles,a binder, a high-boiling-point solvent, and a low-boiling-point solvent, wherein: the contained amount of the chain-like electro-conductive inorganic particles with respect to the total amount of thechain-like electro-conductive inorganic particles and the binder is 30-90 mass%; the binder is an alkoxyl silane having a weight-average molecular weight of 1,000-20,000; and said coating compositionis intended to be used in a liquid crystal display panel that has a TFT array substrate, touch detection electrodes, a liquid crystal layer, and a color filter substrate in order to form an electro-conductive film on a base material surface of said color filter substrate on the opposite side of the liquid crystal layer.

Disclosed is a dye-sensitized solar cell which comprises an electrolyte layer in a solid state, while having improved durability and improved photoelectric conversion efficiency. Specifically disclosed is a dye-sensitized solar cell (1) which is configured of a conductive base (10), a porous semiconductor layer (20) that is formed on the conductive base (10) and loaded with a sensitizing dye on the pore surfaces, a counter electrode (40) that is arranged so as to face the porous semiconductor layer (20), and an electrolyte layer (30) that is formed between the conductive base (10) and the counter electrode (40) and contains potassium iodide and a thermoplastic cellulose resin.

Provided is a colored photosensitive resin composition having good stability over aging. The colored photosensitive resin composition contains: a coloring agent (A); a binder polymer (B); a photopolymerizable compound (C); a photopolymerization initiator (D); and a solvent (E). The solvent (E) contains propyleneglycolmonomethylether acetate and 4-hydroxy-4-methyl-2-pentanone. The colored photosensitive resin composition is preferably used for formation of a color filter.

The present invention discloses a polyester dispersant, which is a hydroxyl group in a vinyl polymer (a) having two hydroxyl groups in one end region, and the above-mentioned vinyl polymer used according to circumstances, and a preparation method thereof. The hydroxyl group in the polyol compound (c) other than the substance (a) reacts with the acid anhydride group in the tetracarboxylic anhydride (b) and the acid anhydride group in the tricarboxylic anhydride (d) used as the case may be, and the above-mentioned ethylene The radical polymer (a) is produced by radically polymerizing an ethylenically unsaturated monomer in the presence of a compound (a1) having two hydroxyl groups and one thiol group in its molecule. The polyester dispersant of the present invention can provide a dispersion with excellent dispersibility, fluidity, and storage stability at a low dosage, and is further suitable for use in offset printing inks, gravure inks, resist inks for color filters, and inkjet inks , coatings, colored resin compositions, etc.
