Abstract

A hydrophilic member includes: a substrate; a first layer and a hydrophilic layer in this order, wherein the first layer contains a polymer and is joined with the substrate and the hydrophilic layer by a chemical bond; and the hydrophilic layer contains a hydrophilic polymer and a metal element selected from Si, Ti, Zr and Al and has a crosslinking structure.

Claims

1. A hydrophilic member comprising:

a substrate;

a first layer and a hydrophilic layer in this order,

wherein the first layer comprises a polymer and is joined with the substrate and the hydrophilic layer by a chemical bond; and

the hydrophilic layer comprises a hydrophilic polymer and a metal element selected from Si, Ti, Zr and Al and has a crosslinking structure.

2. The hydrophilic member according to claim 1, wherein 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.

3. The hydrophilic member according to claim 1, wherein 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.

4. The hydrophilic member according to claim 1, wherein the hydrophilic polymer comprises a compound having a structure represented by the following formula (I) or (II):

5. The hydrophilic member according to claim 4, wherein the reactive group represented by X is a carboxyl group or a salt thereof, a carboxylic acid anhydride group, an amino group, a hydroxyl group, an epoxy group, a methylol group, a mercapto group, an isocyanate group, a block isocyanate group, an alkoxysilyl group, an alkoxy titanate group, an alkoxy aluminate group, an alkoxy zirconate group, an ethylenically unsaturated double bond, an ester linkage or a tetrazole group.

6. The hydrophilic member according to claim 1, wherein the hydrophilic polymer (A) comprises a compound having a structure represented by the following formula (IV-a) or (IV-b):

7. A composition for forming a first layer of a hydrophilic member including a substrate, a first layer and a hydrophilic layer in this order, wherein the first layer comprises a polymer and is joined with the substrate and the hydrophilic layer by a chemical bond.
