[0211] Manufacture of hydroxyl-containing fluoropolymers

[0212] After fully replacing a stainless steel autoclave with an internal volume of 1.5 L with an electromagnetic stirrer with nitrogen, 500 g of ethyl acetate, 75.4 g of perfluoro(propyl vinyl ether), 34 g of ethyl vinyl ether, 41.6 g of ethyl acetate were added. Hydroxyethyl vinyl ether, 50 g of "AdekaReasoap" (manufactured by Asahi Denka Industry Co., Ltd.) as a nonionic reactive emulsifier, 7.5 g of "VPS-1001" as an azo group-containing polydimethylsiloxane (manufactured by Wako Pure Chemical Industries, Ltd.) and 1.25 g of lauroyl peroxide were cooled to -50°C with dry ice-methanol, and then the oxygen in the system was removed with nitrogen.

[0213] Next, 99.1 g of hexafluoropropylene was added, and the temperature was started. When the temperature inside the autoclave reaches 60°C, the pressure is shown as 5.3×10 5 Pa. It was then stirred at 70 °C for 20 hours, and the reaction was continued until the pressu...

[0219] 5.6 g of the hydroxyl group-containing fluoropolymer obtained in Production Example 1, 1.7 g of methoxylated methylmelamine "Saimel 303" (manufactured by Mitsui Techtec Co., Ltd.) as a thermosetting compound, and 0.63 g of a "Kitaristo 4050" (manufactured by Mitsui Techtec Co., Ltd., aromatic sulfonic acid compound, active ingredient concentration 32%) and 1.3 g of hydrophobic colloidal silica with a number-average particle size of 11 nm were dissolved in 211 g of solvent acetone to obtain a liquid Curable resin composition 1. The solid content concentration in the liquid curable resin composition 1 was 4.0% by mass.

Abstract

Disclosed is a liquid curable resin composition containing (A) a fluorine-containing polymer having a hydroxyl group and/or a fluorine-containing polymer having an ethylenically unsaturated group, (B) a curable compound, (C) a curing catalyst, (D) silicon dioxide particles having a number-average particle diameter of not more than 100 nm and (E) a solvent having an sp value of more than 8.5 and less than 12.8. When this liquid curable resin composition is applied to a base and the solvent is removed therefrom, the coating is separated into two layers, namely a layer wherein silicon dioxide exists at high density and a layer wherein substantially no silicon dioxide exists. By curing this coating, there can be obtained a cured film which has excellent adhesion to the base, high abrasion resistance and good antireflection effects.

Description

technical field [0001] The present invention relates to a liquid curable resin composition, in particular to a liquid curable resin composition capable of forming a cured film having high transparency, a low refractive index and good scratch resistance, a cured film composed of the same, and A laminate containing such a cured film. Background technique [0002] Now, with the spread of multimedia, various progress can be seen in various display devices (display devices). Moreover, in various display devices, especially in portable devices for outdoor use, the improvement of the visibility is becoming increasingly important. Even in large-scale display devices, users require easier recognition, so this requirement is natural. become the subject of research. [0003] Conventionally, as a means for improving the visibility of a display device, the display device is covered with an antireflection film made of a low refractive index material, and as a method of forming the antir...
