Title:
Repellent water /is a Oil film.
Document Type and Number:
Japanese Patent JP6115763
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a transparent film onto which excellent water-repellency/oil-repellency and droplet sliding/falling aptitudes have been conferred.SOLUTION: The provided water-repellent/oil-repellent film is a water-repellent/oil-repellent film obtained by forming an organic-inorganic hybrid layer as the outermost layer of a transparent film wherein the organic-inorganic hybrid layer consists of a film having a specified thickness and obtained by mixing, cohydrolyzing, and polycondensing an organosilane expressed by the formula (1) and a tetraalkoxysilane expressed by the formula (2) at a molar ratio of 1 : 0.1-100, wherein the difference, on the surface of the organic-inorganic hybrid layer prevailing as the outermost layer of the transparent film, of the forward contact angle and backward contact angle in relation to a liquid having a surface tension of 18-73 dyn/cm (hysteresis) is of a value lesser than that of a surface which has been surface-treated with the organosilane alone: formula (1): CnH2n+1-Si(OR1)3 [where n=1 to 18; R1=Me or Et]; formula (2): Si(OR2)4 [where R2=Me, Et, Pro, or Bu].
