NOVELTY - A liquid-repellent compound (I) is new.    USE - New liquid-repellent compound is used for polymer for curable composition for forming cured film for manufacture of article (all claimed). Uses include but are not limited to interlayer insulation film for flexible device and multilayer interconnection for high-density package, gate insulating film of memory transistor and organic thin-film transistor, capacitor insulating film, insulating film of organic electroluminescent element and rewiring, cover coat of flexible copper clad board, solder resist film, liquid crystal aligning film and protective film for color filter, semiconductor element, touchscreen and solar cell.    ADVANTAGE - The article having excellent liquid repellency and insulation effect, is efficiently manufactured by the curable composition using the polymer derived from liquid-repellent compound.    DETAILED DESCRIPTION - A liquid-repellent compound of formula (I) is new.    Cf=fluoromethyl, 2-20C fluoroalkyl optionally having ether bond, thioether bond, ester bond, thioester bond, amide bond or urethane bond, fluoroalkenyl or fluoroalkynyl;    -Q-Cf=-C(O)-X-Cf or -CR1=N-X-Cf;    X=divalent organic group containing at least 1 group chosen from group containing -O-, -S-, -C(O)- or -CR2=N-;    Z=CH2=CR3-C(O)-O-R4-;    R1,R2=H, methyl, 2-20C alkyl, alkenyl or alkynyl optionally having ether bond, thioether bond, ester bond, thioester bond, amide bond or urethane bond, 6-30C aryl, 7-30C aralkyl or 2-20C heterocyclyl;    R3=H or methyl;    R4=single bond, -R5-, -R5O-, -R5C(O)O-, -R5OC(O)-, -R5O-C6H4C(O)-, -R5NHC(O)OR6- or -R5S-;and    R5,R6=methylene, 2-20C alkylene, alkenylene or alkynylene optionally having ether bond, thioether bond, ester bond, thioester bond, amide bond or urethane bond, 6-30C arylene, 7-30C aralkylene or 2-20C divalent organic group having heterocyclic ring.    INDEPENDENT CLAIMS are included for the following:    (1) polymer, which has unit (u1) based on the compound (I);    (2) curable composition, which contains polymer;    (3) article, which has a cured film obtained by curing the curable composition, on a surface of a base material; and    (4) manufacture of article, which involves coating the curable composition on the surface of the base material, removing a solvent (E), forming a dry film, irradiating light on the heating of the obtained dry film, obtaining cured film, partially irradiating ultraviolet ray to the surface of the cured film and obtaining article having pattern of lyophilic region and liquid-repellent region on the surface of the cured film, or alternatively partially irradiating ultraviolet ray to the surface of the dry film, forming pattern of lyophilic region and liquid-repellent region in the surface of the dry film, heating or irradiating light and curing the dry film in which the pattern is formed and obtaining article having pattern of lyophilic region and liquid-repellent region on the surface of the cured film.
