TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The process of covering the transparent base material by the transparent substance is carried out by low-pressure plasma processing in mixed atmosphere of oxygen gas and gas of fluorocarbon group-containing compound, such that a fluorine-containing organic thin film is chemically bonded on the surface of base material containing film substance having linear fluorine-containing functional group, in which hydrogen atom(s) is substituted by fluorine atom or fluorocarbon group. The fluorine-containing functional group is chosen from hydrocarbon group, hydrocarbon group having ester group and hydrocarbon group having ether group, preferably Si((-CH3(CH2)n)3)-O- or group of formulae (I)-(IV). The fluorine-containing organic thin film is monolayer of film substance chemically bonded on the surface of base material, and contains polysiloxane molecule derived from alkoxysilane and/or alkoxy polysiloxane. The organic thin film is fixed to surface of base material through film containing polysiloxane molecule. The polysiloxane molecule is obtained by performing condensation reaction of alkoxy polysiloxane of formula: (AO)3Si(OSi(OA)2)lOSi(OA)3 and/or alkoxysilane of formula: SiHx(OA)4-x. The base material has surface roughness of 10-400 nm. The process liquid containing film compound having hydrocarbon group is contacted with the surface of base material, during manufacture of water-oil repellent transparent material. The film compound is silicon-containing compound of formula: Z-SiXpY3-p, preferably CH3(CH2)nSi(OA)3, (CH3(CH2)n)2Si(OA)2, (CH3(CH2)n)3Si(OA), CH3(CH2)m-COO-(CH2)nSi(OA)3 or CH3(CH2)m-O-(CH2)nSi(OA)3.m,n=0-24, where m greater than or equal to n;x,l,p=0, 1 or 2;A=alkyl;Z=substituent containing 25C or less alkyl, aryl, vinyl or silicone group;X=H or substituent containing alkyl, aryl, vinyl or silicone group;andY'=halo or alkoxy.    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The substance having fluorine-containing functional group is fluorine-containing organic polymer having fluorine-containing functional group.
