The present invention addresses the problem of providing a super-liquid-repellent coating film that has improved abrasion resistance. Provided as a means for solving the problem is a coating film that has a fluorine atom content of 1 to 60 wt %, the coating film having a surface that has an average surface roughness Ra of 0.5 to 20, a surface area ratio of 1.7 to 5, a contact angle with water of 150&#xb0; or more, a contact angle with n-hexadecane of 80&#xb0; or more, and a surface that has a contact angle with water of 150&#xb0; or more after being rubbed 100 times with a PET film under a load of 100 g.

Super-liquid-repellent coating film and curable composition for forming super-liquid-repellent coating film

A surface-treating agent including at least one perfluoro(poly)ether group containing silane compound of the formula (1): wherein Rf, PFPE, Z, Q, R, R, X, Y, e, f, g, h and n are as defined herein. Also disclosed is a process for preparing the compound of formula (1).

Surface treating agent including perfluoro(poly)ether-group-containing silane compound

The present invention provides a novel antifouling article comprising a base material, a diamond-like carbon layer and an antifouling coating layer which is formed on the diamond-like carbon layer from a surface treating agent comprising a perfluoropolyether group-containing compound and having high acid resistant and alkaline resistant.

Antifouling article

Provided is an aqueous emulsion composition which has excellent chemical stability (stability with respect to impurities) and excellent mechanical stability. Disclosed is an aqueous emulsion composition which contains: (A) a polymer that contains a fluoroalkyl group; and (B) a surfactant that contains (B1) an amidoamine surfactant having an amide group and an amino group, and (B2) a nonionic surfactant. It is preferable that the surfactant does not contain a monool having an unsaturated triple bond or an alkylene oxide addition product of a polyol.

Aqueous emulsion composition

A composition including a compound containing a carbon-carbon double bond obtained by reacting (A) a polyisocyanate which is a trimer of diisocyanate, with (B) a compound having an active hydrogen, wherein component (B) includes (B1) a perfluoropolyether having an active hydrogen, and (B2) a monomer having an active hydrogen and at least two groups having a carbon-carbon double bond.

Surface treatment composition

Disclosed is a water and oil resistant agent comprising a fluorine-containing copolymer obtained by copolymerizing a (meth)acrylate monomer having a polyfluoroalkyl group having 1 to 6 carbon atoms, the agent being able to afford a superior water and oil resistance to a paper. The invention also discloses a composition comprising the water and oil resistant agent, a process for treating a paper thereby and a treated paper thereby.
