Problems solved by technology

[0007] However, for a resin composition containing a polymer derived from maleimide, since the maleimide-based polymer contains nitrogen atoms, there is a problem that the polymer is colored yellow to yellowish-brown during heating and the cured film may be cured. The problem of insufficient transparency

preparation example Construction

[0279]

[0280] The method for preparing the curable resin composition is not particularly limited, and a known method may be used. For example, a method of mixing and dispersing the above-mentioned components using various mixers and dispersers is mentioned. The mixing / dispersing step is not particularly limited, and may be performed by a known method. In addition, other generally performed steps may be further included. In addition, when the said curable resin composition contains a coloring material, it is preferable to prepare through the dispersion|distribution treatment process of a coloring material.

[0281] As the dispersion treatment process of the above-mentioned coloring material, for example, the following method can be enumerated: first, weighing each predetermined amount of coloring material (preferably an organic pigment), a dispersant, and a solvent, and using a disperser to disperse the coloring material particles to obtain a liquid Pigment dispersion (als...

Embodiment

[0324] The following examples are given to illustrate the present invention in more detail, but the present invention is not limited to these examples. In addition, unless otherwise stated, "part" means "mass part", and "%" means "mass %".

[0325] In this example, measurement conditions of various physical properties and the like are as follows.

[0326]

[0327] Utilize HLC-8220GPC (manufactured by Tosoh Corporation), use tetrahydrofuran as eluent, use TSK-gelSuperHZM-M (manufactured by Tosoh Corporation) as column, measure by gel permeation chromatography, and calculate by standard polystyrene conversion weight average molecular weight.

[0328]

[0329] Accurately weigh about 1 g of the copolymer solution in an aluminum cup, add about 2 g of acetone to dissolve it, and let it stand at room temperature for about 2 hours to allow it to dry naturally. Then, after drying in vacuum at 140 degreeC for 1.5 hours with the vacuum dryer (made by EYELA company), it cooled natur...

Abstract

The present invention provides a polymer that can sufficiently suppress yellowing during heating and can be applied to high coloration; and a curable resin composition containing the polymer. The present invention is a polymer characterized in that it has 10 to 60% by mass of a monomer unit represented by the following general formula (I) and 5 to 80% by mass of -COO * R 4 (R 4 is a monovalent organic group, and O * The bonded carbon atom is a tertiary carbon atom) based vinyl-based monomer unit.

Description

technical field [0001] The present invention relates to a new polymer. More specifically, it relates to a polymer excellent in heat-resistant colorability, a curable resin composition containing the polymer, a color filter having a cured product of the curable resin composition, and a display device. Background technique [0002] Polymers curable by heat or active energy rays are used in various applications depending on the properties of the polymers. Examples of such applications include various optical components such as color filters, inks, printing plates, printed circuit boards, semiconductor elements, and photoresists used in liquid crystal display devices and solid-state imaging devices. For electrical / electronic equipment, etc., studies have been made on copolymers suitable for these applications. [0003] In the above-mentioned applications, the color filter is a main part constituting a liquid crystal display device or a solid-state imaging element, etc., and us...
