Problems solved by technology

The film obtained from the resist composition containing a liquid repellent agent proposed in the aforementioned Patent Document 2 can form such a partition wall, but there are cases where the liquid repellency of the upper surface is insufficient when printing a finer pattern, or The ink affinity of the opening may be insufficient due to the movement of components derived from the fluorine-based surfactant to the side of the partition, and higher performance (expression of higher liquid repellency, effect with a smaller amount of addition) is required liquid repellent

preparation example Construction

[0355] Examples of the method for preparing the pigment dispersion include a method of passing through a colorant kneading and dispersing step and a fine dispersion step, a method of only passing through a fine dispersion step, and the like. In the kneading and dispersing step, the coloring agent, part of the alkali-soluble resin, and the dispersant as needed are mixed and kneaded. The equipment used for kneading can be exemplified: two-roll mill, three-roll mill, ball mill, trommel, disperser, kneader, co-kneader, homogenizer, mixer, single-screw or twin-screw The colorant can be dispersed by using an extruder or the like to disperse while applying a strong shearing force using these kneaders. In addition, it is preferable that the particle size of the coloring agent be made finer by a salt milling method or the like before the above-mentioned kneading.

[0418] Example 1: Production of fluorine-containing active energy ray-curable resin (I-i)

[0419] Add the perfluoropolyether compound (hereinafter abbreviated as "compound (1)" shown in the following formula with a hydroxyl group at both ends to a glass flask equipped with a stirring device, a thermometer, a condenser tube and a dropping device. The hydroxyl equivalent It is 740g / eq. Representing the repeated number of a is 5, b is 7.) 50 parts, 62.5 parts of epichlorohydrin and 20 parts of ethanol. Next, stirring was started under a nitrogen stream, and 8.3 parts of a 49% sodium hydroxide aqueous solution was added dropwise over 2 hours while maintaining the temperature in the flask at 50°C. After completion of the dropwise addition, the temperature was raised to 60°C, stirred for 3 hours, and then returned to room temperature.

[0425] In the glass flask equipped with stirring device, thermometer, condensing tube and dropping device, add the compound (3) shown in the same chemical formula as the aforementioned compound (1), where a is 5 and b is 7 and the hydroxyl equivalent weight is 754g / eq. ) 50 parts, maleic anhydride 6.5 parts. Next, stirring was started under nitrogen flow, the temperature in the flask was raised to 160° C., and stirring was carried out for 1 hour. Then, 0.01 part of dibutyltin dilaurate was added as an esterification catalyst, the temperature in the flask was raised to 170°C, and the mixture was stirred for 5 hours. Then, it was returned to room temperature, thereby obtaining a compound having a poly(perfluoroalkylene ether) chain represented by the following formula (a5-1) and having carboxyl groups at both ends thereof (hereinafter abbreviated as "compound (a5- 1) ".) 56.5 parts.

Abstract

Provided are: a fluorine-containing active energy ray-curable resin which has a resin structure that enables easy adjustment of the fluorine atom content, and which has excellent surface segregation properties, while exhibiting sufficient leveling properties, water repellent oil repellent properties, liquid repellent properties and the like even if the amount of use thereof is small; a liquid repellent agent; a resin composition which contains this fluorine-containing active energy ray-curable resin; and a cured film. Specifically used is a fluorine-containing active energy ray-curable resin which comprises, in each molecule, a residue of an alkylene chain (A), wherein hydroxyl groups are at both ends and at least one hydrogen atom is substituted by a fluorine atom, and a residue of a divalent phenolic hydroxyl group-containing compound (B) other than the component (A) and / or a residue of a divalent carboxylic acid (C), and which has a structural unit wherein the above-described components are bonded by means of a linking group represented by formula (1) (wherein X represents a hydrogen atom, an organic group (x1) having a polymerizable group or an organic group (x2) having an acidgroup). This fluorine-containing active energy ray-curable resin is also configured such that at least one linking group contained in each molecule, said linking group being represented by the above-described structural formula (1), is a monovalent organic group (x1) having a polymerizable group.

Description

technical field [0001] The present invention relates to a fluorine-containing active energy ray curable resin that can be suitably used as a surface modifier for surface smoothness, water and oil repellency, etc. of a cured film, or as a liquid repellent agent, and a resin composition containing the same and its Cured film. Background technique [0002] So far, fluorine-based surfactants or fluorine-based surface modifiers have been widely used in various coatings due to their excellent leveling, wettability, penetrating properties, anti-blocking properties, sliding properties, water and oil repellency, and antifouling properties. Cloth materials, surface modifiers, etc. [0003] A coating formed of an active energy ray-curable composition containing the fluorine-based surfactant or fluorine-based surface modifier (hereinafter collectively referred to as "fluorine-based surfactant") is applied, and the The cured film obtained by its curing exhibits excellent surface proper...
