Background art

[0002] A fluorine-containing compound having a fluorine-containing alkyl group as a hydrophobic group has a high ability to reduce surface tension. Therefore, when it is added as a surfactant to a coating composition, it has excellent permeability and wettability. And exerts effects such as leveling. As the fluorine-containing compound, various structures have been proposed so far.

As fluorine-containing compounds having hydrophilicity, fluorine-containing compounds in which hydrophilic groups are made ionic are known. However, the fluorine-containing compound does not have solubility in an organic solvent.

[0004] As another fluorine-containing compound having hydrophilicity, a fluorine-containing compound having an oxyalkylene group is known (Patent Document 1). Although the fluorine-containing compound is improved in hydrophilicity, the ability to reduce surface tension is poor.

[0055] Additives other than the compound (I) and the like may be added to the rosin.

Additives include hydrocarbon surfactants, silicone surfactants, fluorosurfactants; plasticizers such as DOP (dioctyl phthalate) and DMP (dimethyl phthalate); Stabilizers such as tiltin laurate, norlium sarcophagus; Antioxidants such as BHA (Butylhydroxyl-sol); Agents: various antistatic agents, flame retardants, colorants, lubricants, antibacterial agents, and the like.

According to the method for modifying the surface of a resin of the present invention, the compatibility between the compound (I) and the resin can be used for various types of resins, such as antistatic properties, antifogging properties, antifogging properties, water repellency, lubricity, etc. Can be provided. The same function can also be imparted by applying the surfactant solution of the present invention to the surface of the resin.

[0056] The compound (I) of the present invention described above has a structure derived from an alkylene oxide adduct obtained by adding an alkylene oxide to glycerin or polyglycerin, and therefore, compared with a conventional fluorine-containing compound, Excellent solubility in water. Furthermore, since it has a fluorine-containing alkyl group having 1 to 12 carbon atoms, that is, a fluorine-containing group in which all carbon atoms are connected by a single bond, it has an excellent ability to reduce surface tension compared to conventional fluorine-containing compounds. In contrast, the compound described in Patent Document 1 is not saturated with a fluorine-containing group (C F —, C F —) at the terminal.

6 11 9 17 Since it has a hydrating group and is branched, the ability to reduce surface tension is not sufficient.
