Low refractive layer and anti-reflective film comprising the same

The present invention relates to a low refractive layer and an anti-reflective film comprising the same. The low refractive layer can exhibit excellent optical properties such as a low reflectance and a high light transmittance, and excellent mechanical properties such as high wear resistance and scratch resistance at the same time, without adversely affecting the color of the polymer resin forming the low refractive layer. In particular, due to the excellent alkali resistance, the low refractive layer can maintain excellent physical properties even after alkali treatment. Therefore, when introducing a low refractive layer to the display device, it is expected that the production process can be simplified and further the production rate and the productivity can significantly increase.

Rolling Bearing, Rotating Machine Element, and Solid-Film Formation Method

A method is provided that forms a solid film on a bearing component of a rolling bearing. A solution containing a fluorine compound and a lubricant having no functional group is allowed to adhere to the bearing component as a first liquid film (adhesion step). The adhering first liquid film is hardened to form the solid film on the bearing component. The rolling bearing including the bearing component with the solid film formed thereon is rotated. The rolling bearing is washed in a washer fluid containing the same lubricant as that used in the adhesion step, and the washer fluid is allowed to adhere to the bearing component as a second liquid film. Then, the adhering second liquid film is dried.
