The present invention relates to an anti-fingerprint agent containing a specific fluorine compound. The surface of your fingertips is covered with fat that is deposited when you touch your face or other skin that has sebaceous glands.
When you touch the surface of lacquerware, your fingerprints will stick to it through the fat content. Precision parts such as cameras are protected against dirt, but during the assembly process, manual fingerprints are deposited on them, requiring an extra cleaning process to remove the fingerprints. Further, the stains that adhere to the window glass of automobiles and residences, the glass cases of show windows, etc. are often caused by fingerprints. The present inventor investigated a method to prevent fingerprints from sticking even when fingers touch precision parts made of various materials, other objects that do not like dirt, or transparent objects such as glass, and found that the fluorine compound of the present invention I have come to discover that I can successfully achieve that goal. That is, the present invention relates to an anti-fingerprint agent characterized by containing a compound containing a polyfluoroalkyl group or a polyfluoroether group having 4 to 21 carbon atoms. Compounds containing a polyfluoroalkyl group or a polyfluoroether group (hereinafter simply referred to as R f group) having 4 to 21 carbon atoms include compounds represented by the following general formula () (hereinafter referred to as compounds). , or an unsaturated ester homopolymer containing an R f group or a copolymer of unsaturated esters containing different R f groups (hereinafter referred to as a compound),
Alternatively, a copolymer (hereinafter referred to as a compound) of an unsaturated ester containing an R f group and another copolymerizable compound is suitable. [R f A(X) o ] n Z … () In the above general formula (), R f has 4 carbon atoms

The compound that can be copolymerized with the CH 2 unsaturated ester can be selected from a wide range as long as it does not impede the effects of the present invention. For example, ethylene, vinyl acetate, vinyl chloride, vinyl fluoride, vinylidene halide, styrene, α-methylstyrene, P-methylstyrene, acrylic acid and its alkyl esters, methacrylic acid and its alkyl esters, poly(oxyalkylene) acrylate , poly(oxyalkylene) methacrylate, acrylamide, methacrylamide, diacetone acrylamide, methylolated diacetone acrylamide, N
-methylol acrylamide, vinyl alkyl ether, halogenated alkyl vinyl ether, vinyl alkyl ketone, butadiene, isobrene,
One or more polymerizable compounds that do not contain perfluoroalkyl groups, such as chlorobrene, glycidyl acrylate, benzyl methacrylate, benzyl acrylate, cyclohexyl acrylate, maleic anhydride, aziridinyl acrylate or methacrylate, and N-vinylcarbazole, It is possible to copolymerize it as a constituent unit of a copolymer. The copolymerization ratio of these copolymerization components to the unsaturated ester containing a polyfluoroalkyl group or a polyfluoroether group is generally 1 to 50% by weight, particularly 1 to 20% by weight. In addition, in order to obtain the compounds of the present invention, the raw material polymerizable compound is dissolved in a suitable organic solvent, and a polymerization initiation source (such as a peroxide, an azo compound, or ionizing radiation that is soluble in the organic solvent used) is added. ), a solution polymerization method is usually adopted. Suitable solvents for solution polymerization are toluene,
Ethyl acetate, isopropyl alcohol, 1,1,
These include 2-trichloro-1,2,2-trifluoroethane, tetrachlorodifluoroethane, methylchloroform, and the like. In the present invention, each of the above compounds may be used alone or as a mixture of two or more. In the case of a mixture of three kinds of compounds, it is preferable that the compound be the main component for reasons such as fingerprint adhesion prevention performance and ease of obtaining raw materials. The fluorine content in the fingerprint adhesion prevention agent of the present invention has an effect on the adhesion prevention performance, and it is appropriate that the fluorine content be at least 30% by weight or more, preferably 50% by weight or more. The fingerprint adhesion prevention agent of the present invention is dispersed in water,
Alternatively, the treatment can be carried out by spraying or brushing a dispersion or solution in an organic solvent onto the object to be treated, or by immersing the object in such a dispersion or solution. Examples of organic solvents include ketones such as acetone and methyl ethyl ketone, esters such as methyl acetate, ethyl acetate, and isoamyl acetate, ethers such as diethyl ether and dioxane, methyl chloroform, trichloroethylene, tetrachloroethylene, tetrachlorodifluoroethane, 1,1, 2-trichloro-1,2,
One or a mixture of two or more halogenated hydrocarbons such as 2-trifluoroethane and metaxylene hexafluoride may be employed. If a propellant such as dichlorodifluoromethane, monofluorotrichloroethane, or dichlorotetrafluoroethane is added to such a solvent and the mixture is filled into a suitable container, spray treatment can be performed, and the product dries immediately after treatment, exhibiting adhesion prevention properties. . The amount of the anti-fingerprint agent of the present invention in the solvent or water is usually 0.01 to 10% by weight, preferably 0.1 to 2% by weight. When applying the anti-fingerprint agent of the present invention to an object that requires transparency, such as a window glass, a television screen, or a mirror, it is preferable to select a compound with excellent film-forming properties. The compound has better film-forming properties than the chemical compound, and there is less concern that it will impede transparency. The articles that can be treated with the anti-fingerprint agent of the present invention are not limited at all, and include, for example, glass, paper,
Examples include wood, leather, plastic, metal, ceramics, lacquerware, etc. It is particularly useful for articles that have smooth surfaces to which fingerprints tend to adhere, or for articles that require manual labor during assembly and that do not want to be smudged by fingerprints. Examples of the present invention will be further described below. Example The following fluorine compounds (1) to (5) were each dissolved in 1,1,2-trifluoro-1,2,2-trichloroethane to prepare a 1% by weight solution. A cleaned glass plate was immersed in this solution, pulled out, and dried at room temperature to form a thin film of the fluorine compound. Touch the thus-treated glass plate surface with your finger and visually observe the state of fingerprint adhesion. The results are shown in Table 1.
