Embodiment

[0173] Hereinafter, the present invention will be described in more detail using examples, but the present invention is not limited by the following examples within the range not exceeding the gist. In addition, unless otherwise specified, "part" and "%" are mass standards.

[0174] As the resin (A) in the present invention, synthesis examples of compounds represented by compound structures P-1 to P-5 are shown below.

Synthetic example 1

[0176] 203.9 parts of 1-methoxy-2-propanol (MFG, manufactured by Daicel Chemical Industry Co., Ltd.) was added to the reaction vessel in advance, and the temperature was raised to 70° C. under a nitrogen atmosphere, and 12.5 parts of styrene was instilled over 2 hours, shrinking 76.8 parts of glycerin methacrylate, 66.1 parts of dicyclopentenyl methacrylate, 46.5 parts of methacrylic acid, and 9.5 parts of an azo polymerization initiator (manufactured by Wako Pure Chemical Industries, Ltd., V-65). After dripping, it was allowed to react for 4 hours to obtain a solution (28.6% solution) of the resin represented by Compound Structure P-1.

[0177] The weight average molecular weight Mw of the resin represented by the compound structure P-1 was determined by gel permeation chromatography and found to be 31,500.

Synthetic example 2

[0179] In Synthesis Example 1, except that 2-adamantyl methacrylate was used instead of biscyclopentenyl methacrylate, the resin represented by compound structure P-2 was obtained in the same manner as in Synthesis Example 1. solution (28.0% solution).

[0180] The weight average molecular weight Mw of the resin represented by the compound structure P-2 was 28,700.

Abstract

The invention provides a solidification composite, at least comprising: resin containing radical having branch chain and / or alicyclic structure, radical having acidic group and radical having epoxy group; polymerizability compound; tiators for photopolymerization; and surface activity tiators for photopolymerization. The invention can obtain solidification composite with height deforming recoverability and liquid crystal display displaying unevenly.

Description

technical field [0001] The present invention relates to a curable composition, a cured film, a method for producing an optical spacer, a substrate for a liquid crystal display device, and a liquid crystal display device. Background technique [0002] Liquid crystal display devices are widely used as display devices that display images of high image quality. In a liquid crystal display device, generally, a liquid crystal layer capable of displaying images in a predetermined orientation is disposed between a pair of substrates. Maintaining the distance between the substrates uniformly, that is, the thickness of the liquid crystal layer is one of the factors that determine image quality, so a spacer is provided to keep the thickness of the liquid crystal layer constant. The thickness between the substrates is generally referred to as "cell thickness", and the cell thickness usually indicates the thickness of the liquid crystal layer, in other words, the distance between two el...
