A coating film to prevent a conspicuous fingerprint has a water contact angle of no less than 60&#xb0; so that most of water contained in fingerprints on the coating film evaporates without forming a layer adsorbed on the coating film. Further, the coating film has lipophilicity and has a diiodomethane contact angle of no more than 45&#xb0; so that the coating film exhibits enhanced affinity to fingerprints, which primarily contain oily components.

Composition for coating film to prevent conspicuous fingerprints, coating film to prevent conspicuous fingerprints using the composition, and article having the coating film

Disclosed herein is an anti-fingerprint coating composition, a coating composition for forming thin films that prevents fingerprints adhered to displays or touch panels from being remarkably visible and exhibits superior durability and slip properties, and a method for preparing the same. The anti-fingerprint coating composition is prepared by mixing a silane compound having an alkyl group with distilled water or acid.

A coating structure and a method for forming the same where, by forming an aluminum oxide layer and a silicon dioxide layer between a product to be coated and a coating layer, durability, reliability and anti-corrosion of the coating layer can be improved and furthermore, product yield can also be improved. The coating structure formed on the surface of a product includes an aluminum oxide (AlO) layer formed on the surface of the product, a silicon dioxide (SiO) layer formed on the surface of the aluminum oxide (AlO) layer, and a coating composition layer formed on the silicon dioxide (SiO) layer.

Coating structure and method for forming the same

Provided is an ink composition including a colorant; a solvent; a surfactant; and an oxygen absorber of a hetero ring compound and a hydroxylamine-based compound. The oxygen absorber lowers a concentration of oxygen dissolved in the ink composition and maintains a low level even when the ink composition is in a high-temperature condition. Thus, gas is substantially not generated and bubbles are not formed. The ink composition can be stably ejected during high-speed printing.
