An ink jet ink including a pigment and an ABC triblock polymer, wherein the above-described ABC triblock polymer is formed from an A block having an aryl group, a B block having a unit represented by the following general formula (1), and a C block having a unit represented by the following general formula (2). 

Ink jet ink, ink cartridge, and ink jet recording method

An ink jet liquid composition which is used with an ink containing a pigment and which contains an ABC triblock polymer formed from an A block having an aryl group, a B block having a unit represented by the general formula (1), and a C block having a unit represented by the general formula (2), wherein an acid value of the polymer is 20 mgKOH/g or more and less than 150 mgKOH/g, the ratio of the number average molecular weight of the polymer to the acid value is 50 or more and 200 or less, the proportion of the A block in the polymer is 20.0 percent by mass or more and 80.0 percent by mass or less and is 5.0 times or more and 15.0 times or less the proportion of units derived from all acidic monomers contained in the polymer.

A color filter including: a transparent substrate; a light shielding part formed on the transparent substrate and contains at least a light shielding material and a resin; and a colored layer formed in the opening part of the light shielding part on the transparent substrate to cover a part of the light shielding part. The light shielding part has: the width of the thick film region, 85% of more of the maximum film thickness of the light shielding part and disposed in the central part of the light shielding part, in a range of 30% to 60% of the light shielding part line width; and the width of each of the thin film regions, 50% or less of the maximum film thickness of the light shielding part and disposed on the both side parts of the light shielding part, in a range of 10% to 20% of the light shielding part line width.

Method for producing a color filter

A black resin composition for a display device, which can achieve a high optical density even when its light-blocking agent content is relatively low and can achieve a high optical density even when it is formed into a thin film, and a member for display device which can reduce unevenness of display caused by a level difference in a pixel part resulting from the film thickness of the black resin composition. The black resin composition for a display device has a black titanium oxynitride represented by composition formula: TiNOSiO(wherein x and y each are a real number of larger thanbut less than, and n is a real number within the range ofless than or equal to n less than or equal to), containing a nitrogen atom represented by N in an amount ofwt % or more but less thanwt %, and having a specific surface area oftom/g and a crystalline size as measured with an X-ray diffractometer oftonm, and a curable binder system. Also, a member for display device having a light-blocking layer formed using the said black resin composition for display device.
