Problems solved by technology

However, in this case, if a large amount of lactone effective for developability is added, the molecular weight becomes too large, so there are problems such as solvent solubility and developability deterioration.
Therefore, a sufficient amount of lactone cannot be introduced into the linear random copolymer, and a good developability improvement effect cannot be obtained.
In addition, the above-mentioned linear random polymer containing lactone has a small effect of inhibiting the aggregation of pigments, and it is necessary to use another dispersant in combination to achieve dispersibility. As a result, there is a problem that a large amount of linear random polymer containing lactone cannot be added.

preparation example Construction

[0350] In preparation of the alkali-soluble resin, for example, a method by a known radical polymerization method can be employed. Various polymerization conditions such as temperature, pressure, the type and amount of the radical initiator, the type of solvent, etc. when preparing the alkali-soluble resin by the radical polymerization method can be easily set by those skilled in the art. Conditions can be determined experimentally.

[0351] As the linear organic high molecular polymer, a polymer having a carboxylic acid in a side chain is preferable. For example, in the publications of JP-A No. 59-44615, No. 54-34327, No. 58-12577, No. 54-25957, No. 59-53836, and No. 59-71048 Methacrylic acid copolymers, acrylic acid copolymers, itaconic acid copolymers, crotonic acid copolymers, maleic acid copolymers, partially esterified maleic acid copolymers, etc., as described in Acidic cellulose derivatives, polymers obtained by addition of polymers having hydroxyl groups and acid an...

Description

technical field [0001] The present invention relates to a pigment dispersion composition that can be used when constituting image materials such as color filters and color proofs, photocurable materials such as inks and paints, and pigment dispersion compositions suitable for forming liquid crystal display devices, solid-state imaging devices, etc. A photocurable composition for a color filter, a color filter using the curable composition, a method for producing the same, a liquid crystal display element, and a solid-state imaging element. Background technique [0002] In recent years, the use of color filters not only in displays for liquid crystal display elements (LCDs) but also in televisions (TVs) tends to expand. With the expansion of this use, high color characteristics are required in terms of chromaticity, contrast, and the like. In addition, in applications of solid-state imaging devices (image sensors) similarly, high color characteristics such as reduction of co...
