Title:
WATER-REPELLENT FILM, FILM HAVING PATTERN WITH WATER-REPELLENT AND HYDROPHILIC REGIONS, AND PROCESS FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2010/137542
Kind Code:
A1
Abstract:
A process for producing an ultrahigh water-repellent film comprising a polymer having a fine surface structure (rugged structure), in particular, a process for producing an ultrahigh water-repellent film on the basis of the phase separation of a polymer caused by polymerization induced by irradiation with energy rays, and an ultrahigh water-repellent film formed by the process.
The process for producing an ultrahigh water-repellent film comprises the step of producing a film-forming composition (X) by mixing a polymerizable compound (A) that is capable of polymerizing upon irradiation with energy rays with a compound (B) that is incompatible with a polymer of the polymerizable compound (A) and the steps of forming a layer of the film-forming composition (X), polymerizing the polymerizable compound (A), and then removing the compound (B), the compound (B) being a compound which is liquid or solid, has a molecular weight of 500 or lower, and a saturated vapor pressure at 25ºC of 400 Pa or lower.
