양호한 발수 발유 특성을 갖고, 또한 내마모성을 한층 더 향상시킨 발수 발유 코팅 조성물 및 이것으로부터 얻어지는 투명 피막을 제공하는 것을 목적으로 한다. 본 발명은 퍼플루오로알킬기 또는 퍼플루오로폴리에테르기를 자유단측에 갖는 불소 함유기와, 가수분해성기가 규소 원자에 결합되어 있는 제1 유기 규소 화합물(A)과, 가수분해성 실란 올리고머, 혹은 불화탄소 함유기와 가수분해성기가 규소 원자에 결합된 화합물이며, 온도 100℃에서의 증기압이 1기압 이하인 제2 유기 규소 화합물(B)을 포함하는 발수 발유 코팅 조성물이다. The present invention aims to provide a water-repellant and oil-repellant coating composition which has good water-repellant and oil-repellant characteristics and further improves abrasion resistance, and a transparent film produced therefrom. The present invention is a water-repellant and oil-repellant coating composition comprising a first organic silicon compound (A) in which a fluorine-containing group having a perfluoroalkyl group or a perfluoropolyether group on the free end side thereof and a hydrolyzable group are bonded to a silicon atom thereof, and a second organic silicon compound (B) that is a hydrolyzable silane oligomer or a compound in which a carbon fluoride-containing group and a hydrolyzable group are bonded to a silicon atom thereof and that has a vapor pressure at 100° C. of 1 atm or less.
