Problems solved by technology

However, when the pigment concentration is increased, the content of the dispersion resin and alkali-soluble resin in the curable composition will inevitably decrease, so the dispersibility, dispersion stability and developability will deteriorate, and the problem of pattern formation will become difficult.

Embodiment

[0442] Hereinafter, although an Example demonstrates this invention in more detail, this invention is not limited to this.

[0443] It should be noted that, in the examples, the acid value and the amine value use the potential difference method (solvent tetrahydrofuran / water=100 / 10 (volume ratio), titration solution 0.01N sodium hydroxide aqueous solution (acid value) 0.01N hydrochloric acid ( Amine value)) to decide. However, in Example 18 and Example 29, instead of the 0.01N aqueous sodium hydroxide solution, the titration was performed with a 0.01N sodium methoxide dioxane solution system.

Synthetic example 1

[0444] (Synthesis example 1) Synthesis of polyester (i-1)

[0445] 6.4 g of n-octanoic acid, 200 g of ε-caprolactone, and 5 g of tetrabutoxytitanium (IV) were mixed, heated at 160° C. for 8 hours, and then cooled to room temperature to obtain polyester (i-1).

[0446] The diagram is shown below.

[0447] [chem 36]

[0448]

Synthetic example 2～10

[0450] Polyesters (i-2) to (i-10) were obtained in the same manner as in Synthesis Example 1 except that the amount of preparation was described in Table 1. The number-average molecular weight and weight-average molecular weight of the resins obtained in these synthesis examples were measured by the GPC method already described. The results are shown in Table 1 below. In addition, the number of lactone repeating units calculated from the raw material charging ratio is also shown in Table 1 below.

Abstract

Disclosed is a resin having (i) a main chain portion containing a nitrogen atom, (ii) a group ''X'' having a functional group with a pKa of not more than 14 and bonded to a nitrogen atom in the main chain, and (iii) an oligomer chain or polymer chain ''Y'' having a number average molecular weight of 500-1,000,000, which forms a side chain.

Description

technical field [0001] The present invention relates to a novel resin useful as a pigment dispersant, its production method, and a pigment dispersion liquid containing the resin, which are preferably used in the production of liquid crystal display elements (LCD) and solid-state imaging elements (CCD, CMOS, etc.) A colored curable composition for a color filter to be used, a color filter having a colored region formed from the colored curable composition, and a method for producing the same. Background technique [0002] Color filters are essential components of liquid crystal displays and solid-state imaging devices. A color filter is produced using a curable composition containing a colorant (pigment or dye). When the colorant is a pigment, it is necessary to add a dispersant in order to ensure dispersibility and dispersion stability. In particular, polymer dispersants have been developed as dispersants excellent in dispersibility and dispersion stability (see, for examp...
