The film which shows the refractive index of 1.28-1.41 and the water contact angle of 90-115 degree on a base material, and was formed in close contact with the surface of the said base material is provided.n n n Silicon compound (A) represented by Si (OR) 4 , CF 3 (CF 2 ) n CH 2 CH 2 silicon compound (B) represented by Si (OR 1 ) 3 , and H 2 NCONH (CH) m Si A reaction mixture containing a silicon compound (C) represented by (OR 2 ) 3 , an alcohol (D) represented by R 3 CH 2 OH and an oxalic acid (E) in a specific ratio is formed, and the reaction mixture is a ratio of water. Polysiloxane solution is produced by heating at 40-180 degreeC in presence, the coating liquid containing this solution is apply | coated to the surface of a base material, and the coating film is formed in close contact with the surface of the said base material by thermosetting at 40-450 degreeC, 1.28 The film which shows the refractive index of -1.41 and the water contact angle of 90-115 degree, the formation method of this film, and the manufacturing method of this coating liquid. |
