[0166] The types of compounds shown in Table 1 were mixed in the mass ratio shown in Table 1 to prepare a thiol curable composition. In Table 1, the ratio of the number of functional groups represents (number of mercapto groups in compound (A)) / (number of carbon-carbon unsaturated bonds in diallyl maleate and / or diallyl fumarate).

[0168] A mold release PET film and a 0.2 mm silicone spacer were sequentially placed on a glass plate, filled with a thiol-ene curable composition, and a mold release PET film and a glass plate were sequentially placed thereon and fixed with a jig. Next, irradiate 1J / cm from both sides using a conveyor belt type UV irradiation machine ECS-4011GX (high pressure mercury lamp) manufactured by Aigraphy Co., Ltd. 2 UV light to obtain a test piece with a thickness of 0.2 mm. The obtained test piece is cut into a rectangle with a width of 4mm and a length of 50mm, and under the environment of 23°C, the tensile test is carried out under the con...

Abstract

Provided is a thiol-ene curable composition which achieves both sufficient elongation properties and elasticity, and ensures the preservation stability of a formulation. This thiol-ene curable composition is characterized by comprising at least one among a compound (A) having an isocyanuric skeleton and at least two mercapto groups in one molecule, and a compound (B) including diallyl maleate anddiallyl fumarate. The compound (A) is at least one selected from 1,3,5-tris(3-mercapto butyryloxy ethyl-1,3,5-triazine-2,4,6(1H, 3H, 5H)-trione, tris[(3-mercapto propionyloxy)-ethyl]-isocyanurate, andtris(mercapto propyl)isocyanurate.

Description

technical field [0001] The present invention relates to a thiol-ene curable composition and a cured product thereof capable of obtaining a cured product having high elongation properties and elasticity, and having a good storage stability of the complex. Background technique [0002] The reaction of a thiol compound with a carbon-carbon double bond compound is known as a thiol-ene reaction, and a review is reported academically in Non-Patent Document 1. [0003] When the carbon-carbon double bonded compound is a (meth)acrylic compound, the carbon-carbon double bonded compound and the thiol compound react at a functional group molar ratio of about 1 to 1 to form a thioether bond, so it becomes a homogeneously functional compound. sexual solidification. In addition, it is known that it is not easily hindered by oxygen, so it is excellent in productivity and attention is drawn to high elongation characteristics and transparency. [0004] Patent Document 1 discloses a thermall...
