탄소수 6 이하의 퍼플루오로알킬기를 갖는 화합물을 수계 매체에 용해 또는 분산시킨 수성액을 포함하는 발액제 조성물을 수지 성형체의 표면에 균일하게 도포할 수 있어, 우수한 발액성을 갖는 발액성 성형체가 얻어지는 발액성 성형체의 제조 방법의 제공. 탄소수 4 ∼ 6 의 퍼플루오로알킬기를 갖는 단량체에 기초하는 구성 단위를 갖는 함불소 공중합체와, 물과, 탄소수 1 ∼ 4 의 알코올을 포함하는 발액제 조성물을, 수지 성형체에 도포하고, 발액성 성형체를 제조하는 방법으로서, 상기 알코올의 함유량이, 상기 발액제 조성물 100 질량％ 에 대하여 70 ∼ 99.9 질량％ 이고, 상기 수지 성형체에 대한 상기 발액제 조성물의 도포량이, 불소 원자량으로 하여 0.001 ∼ 0.2 g/㎡ 인 것을 특징으로 하는 발액성 성형체의 제조 방법. To provide a method for producing a liquid repellent molded product, whereby it is possible to uniformly apply, on the surface of a resin molded product, a liquid repellent composition containing an aqueous liquid having a compound having a perfluoroalkyl group with at most 6 carbon atoms dissolved or dispersed in an aqueous medium, and to obtain a liquid repellent molded product having excellent liquid repellency. The method for producing a liquid repellent molded product, comprises applying a liquid repellent composition comprising a fluorinated copolymer having structural units based on a monomer having a C 4-6 perfluoroalkyl group, water and a C 1-4 alcohol, to a resin molded product, and is characterized in that the content of the alcohol is from 70 to 99.9 mass% based on 100 mass% of the liquid repellent composition, and the application amount of the liquid repellent composition to the resin molded product is from 0.001 to 0.2 g/m 2 as the amount of fluorine atoms.
