Definitions

• the present invention relates to a novel fluorine-containing silicone copolymer useful as a surface treatment agent and a surface modifier for imparting antifouling properties to be used in the fields of glass, fibers, metals, resins, films, optical materials, paints and the like. About.
• Coating liquids used in the fields of resins, optical materials, paints, etc. suppress defects such as streaks, repellency, unevenness, irregularities, and non-wetting that occur during the coating process on the surface of the member.
• Various substances are added for the purpose of imparting smoothness to the film surface.
• a compound containing a perfluoroalkenyl group is also used as an additive in this application, and in particular, a nonionic surfactant having a perfluoroalkenyl group is known to be useful in terms of imparting surface smoothness.
• a nonionic surfactant having a perfluoroalkenyl group is known to be useful in terms of imparting surface smoothness.
• Thin displays, PC monitors, mobile phones, portable game consoles, car navigation systems, etc. are used in various environments, especially on the screens of devices that have become touch panels, such as fingerprints, magic inks, cosmetics, etc. Easy to get dirty.
• a method for improving the water and oil repellency of the screen surface has been proposed.
• a method of introducing a fluorine compound or a silicon compound is proposed.
• the method of introducing is known and widely used (for example, Patent Document 2).
• fluorine compounds can provide surface smoothness and fingerprint wiping properties
• Silicon compounds can improve surface slipping, magic ink wiping properties, and scratch resistance.
• the fingerprint wiping property was poor.
• the fluorine compound and the silicon compound have extremely poor compatibility and are liable to cause phase separation.
• There are problems such as a region in which the fluorine compound is aggregated on the surface by the phase separation and a region in which the fluorine compound is aggregated (white turbidity), resulting in a decrease in surface visibility. Therefore, a sufficient amount of fluorine compound for imparting antifouling properties could not be mixed with the silicon compound.
• Patent Document 3 many techniques for introducing a compound partially having a fluorine group added into a silicone compound have been proposed (for example, Patent Document 3). Since this technique is a technique of introducing fluorine or the like into various types of silicon compounds, there is an advantage that the degree of freedom in design is high, but since it is a special compound, it cannot be easily obtained. In addition, since such a compound does not chemically bond with the curing component in the coating liquid, it will escape from the cured resin film over time or with an external stimulus, and the water / oil repellent effect will be lost. Furthermore, there is a problem that it exhibits a plasticizer action in the film and lowers the film strength.

• a glass plate 100 mm ⁇ 100 mm ⁇ 2 mm, used after degreasing acetone
• a spin coater Mikasa 1H07
• Example 14 Without adding a fluorine-containing silicone copolymer, 20 parts by mass of a phenolic resin is added to propylene glycol monomethyl ether acetate, and a spin coater (1H07 made by Mikasa) is used on a glass plate (100 mm ⁇ 100 mm ⁇ 2 mm, used after degreasing acetone). The coating process was performed. Then, it was dried at 100 ° C. for 90 seconds. The surface condition was confirmed, and the contact angles of water and hexadecane were measured using a DropMaster 700 manufactured by Kyowa Interface Science Co., Ltd. The measurement results are shown in Table 3.
