manufacture example 1

[0322] (1) Synthesis of organic compounds having polymerizable unsaturated groups

[0323] Into a mixed solution of 221 parts of mercaptopropyltrimethoxysilane and 1 part of dibutyltin dilaurate in a container equipped with a stirrer, isophorone diacetate was dropped at 50° C. for 1 hour in dry air. After 222 parts of isocyanate, it stirred at 70 degreeC for 3 hours.

[0324] Next, NK ester A-TMM-3LM-N (consisting of 60% by mass of pentaerythritol triacrylate and 40% by mass of pentaerythritol tetraacrylate. Only the pentaerythritol triacrylate which has a hydroxyl group participated in the reaction.) After 549 parts, it stirred at 60 degreeC for 10 hours, and obtained the reaction liquid.

[0325] When the amount of residual isocyanate of the organic compound having a polymerizable unsaturated group, which is a product in the reaction liquid, was measured by FT-IR, it was 0.1% by mass or less, and it was confirmed that each reaction proceeded substantially quantitatively. I...

[0327] (2) Synthesis of urethane acrylate

[0328] In a container with a stirrer, NK Ester A- After 93 parts of TMM-3LM-N (only the pentaerythritol triacrylate having a hydroxyl group participated in the reaction), it was stirred at 60° C. for 6 hours to form a reaction liquid.

[0329] When the product in the reaction liquid, ie, the amount of remaining isocyanate was measured by FT-IR in the same manner as in Production Example 1, it was found to be 0.1% by mass or less, and it was confirmed that the reaction proceeded substantially quantitatively. In addition, it was confirmed that a urethane bond and an acryloyl group (polymerizable unsaturated group) were contained in the molecule.

[0330] By the above operations, in addition to obtaining 75 parts of urethane hexaacrylate compounds, a composition (A-2) in which 37 parts of pentaerythritol tetraacrylates that did not participate in the reaction were mixed was obtained.

[0332] [Preparation of a composition for a hard coat layer containing silica particles]

[0333] 2.32 parts of the polymerizable unsaturated group-containing composition (A-1) produced in Production Example 1, silica particle sol (methyl ethyl ketone silica sol, manufactured by Nissan Chemical Industry Co., Ltd. MEK- ST, number average particle diameter 0.022μm, silica concentration 30%) 91.3 parts (27 parts as silica particles), ion-exchanged water 0.12 parts and 0.01 parts of p-hydroxyphenyl monomethyl ether, at 60 After stirring at °C for 4 hours, 1.36 parts of methyl orthoformate was added, followed by heating and stirring at the same temperature for 1 hour to obtain reactive particles (dispersion liquid (A-3)). After weighing 2 g of this dispersion liquid (A-3) in an aluminum dish, it was dried on a 175° C. hot plate for 1 hour, and the solid content was determined by weighing, and it was 30.7%. In addition, after weighing 2g of the dispersion liquid (A-3) in a magnetic ...

Abstract

Disclosed is a curable liquid resin composition comprising: (A) a fluorine-containing polymer; (B) a thermosetting compound; (C) a curing catalyst; (D) metal oxides particles having a number average particle diameter of not more than 100 nm; (E-1) one or more solvents having a high solubility for the fluorine-containing polymer (A) (hereinafter referred to as a highly volatile solvent (E-1)); (E-2) one or more solvents which has high dispersion stability for the metal oxide particles (D) and is compatible with the highly volatile solvent (E-1) (hereinafter referred to as a less volatile solvent (E-2)); and (F) an active energy ray-curable compound. The curable liquid resin composition is characterized in that the relative evaporation rate of the highly volatile solvent (E-1) is higher than that of the less volatile solvent (E-2). Also disclosed is a cured film made from such a curable liquid resin composition.

Description

technical field [0001] The present invention relates to a liquid curable resin composition and a method for producing a laminate using the same, and more particularly to a liquid curable resin composition capable of forming two or more layers from one coating film and a laminate using the same manufacturing method. Background technique [0002] Now, along with the development of multimedia, various advances are manifested in various display devices. In addition, in various display devices, especially display devices that can be used outdoors mainly for portable use, the improvement of the visibility is becoming more and more important, and demanders demand that even in large-scale display devices and the matter remains a technical subject. [0003] Conventionally, as a method of improving the visibility of a display device, a method of covering a substrate of a display device with an antireflection film made of a low-refractive index material has been used. Plating is a m...
