Title:
ANTI-FOG COATING
Document Type and Number:
WIPO Patent Application WO/2022/176510
Kind Code:
A1
Abstract:
The anti-fog coating according to one embodiment of the present invention includes a resin component (A) having structural units based on a (meth)acrylamide monomer represented by CH2=CH-CO-NR1R2 and structural units based on at least one hydrophobic monomer selected from the group consisting of (meth)acrylate monomers having a hydrocarbon group and styrene monomers and an amorphous silica (B) having an average primary particle size of 60 nm or less. The proportion of structural units based on the (meth)acrylamide monomer is 30-75 mass% relative to the total structural units constituting the resin component (A), and the proportion of the amorphous silica (B) is 74-87 mass% relative to the total of the resin component (A) and the amorphous silica (B). R1 and R2 each independently are a hydrogen atom or an alkyl group, or R1 and R2 bond to form a nitrogen-containing heterocyclic group together with N.
