Embodiment

[0027] Embodiments of the present invention will be described below.

[0028] Mixing ratio I

[0029] Organic compound: organic nitrogen compound = 10:30

[0030] 7.5% of an antifouling additive was added based on the amount of solid content of the mixed solution.

[0031] Mixing ratio I I

[0032] Organic compound: organic nitrogen compound = 10:40

[0033] 10.5% of the antifouling additive was added based on the solid content of the mixed solution.

[0034] Mixing ratio III

[0035] Organic compound: organic nitrogen compound = 20:40

[0036] 16.5% of antifouling additive was added based on the solid content of the mixed solution.

[0037] As for the mixed solution actually used, the organic compound was KZ6154, and the organic nitrogen compound was Beam-set 575 CB. The antifouling additive is Optool DAC.

[0038] The organic nitrogen compound and the antifouling additive are propylene glycol monomethyl ether except the organic compound having a ketone group.

Abstract

The invention provides a coating liquid capable of reducing fingerprint adhesion and manufacturing method thereof, based on solution total amount by solid content, the organic compound containing ketone group and the organic nitrogen compound are mixed according to 10-40%. 0.1%-20.0% of antifoulant additive is added into the mixture liquid based on the amount of the solid content of the mixture liquid.

Description

technical field [0001] The present invention relates to a coating liquid for reducing adhesion of fingerprints to glass, metal, etc., a method for producing the coating liquid, and an article coated with the coating liquid. Background technique [0002] The composition of fingerprints is composed of water-like substances such as sweat and oily substances. In general, fingerprint soil is thought to be a combination of watery and oily substances. [0003] On the other hand, sweat contains water, inorganic components such as sodium chloride and potassium chloride, organic components such as lactic acid and amino acids, free fatty acids, etc. Therefore, it is necessary to coat the surface of the product with components having the following functions at the same time. [0004] (a) Water repellency to block aqueous soil and make it easy to remove. [0005] (b) Oil repellency to block aqueous soil and make it easy to remove. [0006] Japanese Patent No. 3389605 describes a wate...
