Patent ID: 8227085

Claim:
An anti-fogging article comprising a substrate and a water-absorptive crosslinked resin layer formed on the surface of the substrate, wherein the water-absorptive crosslinked resin is a crosslinked resin with a saturated water absorption of at least 45 mg/cm 3 , and which water-absorptive crosslinked resin is a resin obtainable by reacting a polyglycidyl ether compound, a curing agent and a coupling agent, wherein the polyglycidyl ether compound is at least one member selected from the group consisting of glycerol polyglycidyl ether, diglycerol polyglycidyl ether, polyglycerol polyglycidyl ethers and sorbitol polyglycidyl ether, and wherein the curing agent is curing agent (A) or curing agent (B), when the curing agent is curing agent (A), which is a compound having at least two reactive groups capable of reacting with an epoxy group in the polyglycidyl ether compound, the polyglycidyl ether compound is present in an amount of from 40 to 80 mass % based on the total of the polyglycidyl ether compound, the curing agent and the coupling agent, and when the curing agent is curing agent (B), which is a compound to accelerate formation of the crosslinked resin by catalyzing a crosslinking reaction of the polyglycidyl ether compound, the polyglycidyl ether compound is present in an amount of from 60 to 95 mass % based on the total of the polyglycidyl ether compound, the curing agent and the coupling agent, wherein the water-absorptive crosslinked resin layer has a thickness of from 5 to 30 μm, and wherein the substrate comprises glass.
