Abstract

The present invention addresses the problem of providing a super-liquid-repellent coating film which has improved wear resistance. Provided as a means for solving the problem is a coating film havinga surface which has a fluorine atom content of 1-60 wt%, an average surface roughness Ra of 0.5-20, a surface area ratio of 1.7-5, a contact angle with water of 150 DEG or greater, and a contact anglewith n-hexadecane of 80 DEG or greater and, after a PET film is rubbed thereagainst 100 times under a load of 100 g, has a contact angle with water of 150 DEG or greater.

Description

technical field [0001] The present invention relates to a film, especially a super-water-repellent film capable of imparting super-water-repellent properties and super-oil-repellent properties (hereinafter, collectively referred to as "super-liquid-repellent properties") to the surface, and also relates to a film capable of forming the super-water-repellent film curable film-forming composition. Background technique [0002] Various superhydrophilic coatings have been proposed. [0003] For example, a method of imparting super-liquid repellency by chemically bonding a fluoroalkylsilane compound to a surface to be treated on which a cured coating film containing silica fine particles or the like is formed has been proposed (Patent Document 1). [0004] A method of forming a film by hydrolyzing an alkoxysilane in a state where an alkoxysilane, a perfluoroalkylsilane, and silica fine particles are mixed has also been proposed (Patent Document 2). [0005] In addition, a film ...
