TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: In the hydrophilic member, a side of the first layer on which the substrate is provided is hydrophobic, and a side of the first layer on which the hydrophilic layer is provided is hydrophilic. The chemical bond is at least one of a urethane linkage, a urea linkage, an amide linkage, an ester linkage, an ether linkage, a carbon-carbon linkage, an N-C linkage, an S-C linkage and a siloxane linkage. The hydrophilic polymer comprises alkyl compound of formula (X-A-(CH(R1)-C(R2)(L1)(Y1))-) (I), alkyl compound of formula (-CH(R3)-C(R4)(L2)(B1)-)(-CH(R5)-C(R6)(L3)(X)-) (II), alkyl compound of formula (-(C(R1)(R3)-C(R2)(L1)-X)x-) (IVa) or alkyl silane compound of formula (-(C(R4)(R6)-C((R5)(L2)-SiR73-m(OR8))m)y-).R1-R6 = H or 1-8C hydrocarbon;X = reactive group, preferably carboxyl or its salt, carboxylic acid anhydride, amino, OH, epoxy, methylol, mercapto, isocyanate, block isocyanate, alkoxysilyl, alkoxy titanate, alkoxy aluminate, alkoxy zirconate, ethylenically unsaturated double bond, ester linkage or tetrazole ;A, L1-L3 = single bond or connecting group;Y1 = -NHCOR7, -CONH2, -CON(R7)2, -COR7, -OH, -CO2M, -SO3M, -PO3M, -OPO3M or -N(R7)3Z1;R7 = 1-18C alkyl, 1-18C aryl or 1-18C aralkyl;M = H, alkali metal, alkaline earth metal or onium;Z1 = halogen ion; andB1 = alkyl group of formula (-CH(R1)-C(R2)(L1)(Y1)-).In formula (IVa-IVb)R1-R8 = H or 1-8C hydrocarbon;L1 = single bond or polyvalent organic connecting group;L2 = single bond or polyvalent organic connecting group having at least one structure comprising -CONH-, -NHCONH-, -OCONH-, -SO2NH or SO3-;X = -OH, -ORa, -CORa, -CO2Re, -CON(Ra)(Rb), -N(Ra)(Rb), -NHCORd, -NHCO2Ra, -OCON(Ra) (Rb), -NHCON(Ra)(Rb), -SO3Re, -OSO3Re, -SO2Rd, -NHSO2Rd, -SO2N(Ra)(Rb), -N(Ra) (Rb)(Rc)-N(Ra)(Rb)(Rc)(Rg)-PO3(Re)(Rf), -OPO3(Re)(Rf) or -PO3(Rd)(Re);Ra-Rc = H 1-8C alkyl (optionally saturated);Rd = 1-8C alkyl (optionally saturated);Re, Rf = H, 1-8C alkyl (optionally saturated), alkali metal, alkaline earth metal or onium;Rg = 1-8C alkyl (optionally saturated), halo, inorganic anion or organic anion; eitherx, y = 100-0; orx+y = 100; andm = 1-3. EXAMPLE - Polyethylene terephthalate substrate (thickness: 50 mu m), a surface of which had been hydrophilized by a glow treatment, was prepared. First layer coating solution (comprising Epikote 1009 (RTM: Epoxy-4,4'-isopropylidenediphenol) (100 g), Takenate D110N (RTM: Ethyl acetate solution (75%)) (100 g), and methyl ethyl ketone (1200)) was spin coated and dried in an oven at 100 degrees C for 2 minutes to form a first layer at a dry coverage of 0.5 g/m2. The first layer had a water droplet contact angle of 80 degrees . Subsequently, a hydrophilic layer coating solution (comprising aqueous solution of colloidal silica (100 g), sol-gel preparation (tetramethoxysilane (8 g) and silane coupling group-terminated hydrophilic polymer were mixed in ethyl alcohol (200 g), acetyl acetone (10 g), tetraethyl orthotitanate (10 g) and purified water (100 g))) was spin coated on the first layer and dried in an oven at 100 degrees C for 10 minutes to form a hydrophilic layer at a dry coverage of 2 g/m2 to obtain hydrophilic member.
