An antifoggant composition, comprising: a copolymer (A); a blocked polyisocyanate curing agent (B); a colloidal silica (C); a surfactant (D); and water (E), wherein the copolymer (A) is a (meth)acrylate copolymer obtained from a monomer mixture containing an N,N-dialkyl (meth)acrylamide monomer (a-1) represented by General Formula (1): [chemical expression included] (wherein R1 is a hydrogen atom or a methyl group, and R2 and R3 are independently a linear or branched alkyl group having 1 to 8 carbon atoms); an ε-caprolactone-added hydroxyalkyl (meth)acrylate monomer (a-2) represented by General Formula (2): [chemical expression included] (wherein R4 is a hydrogen atom or a methyl group, and n is an integer of 1 to 10); and a (meth)acrylate monomer (a-3) having a hydrocarbon group represented by General Formula (3): [chemical expression included] (wherein R5 is a hydrogen atom or a methyl group, and R6 is a linear, branched, or cyclic hydrocarbon group having 1 to 22 carbon atoms), and an amount of the blocked polyisocyanate curing agent (B) is 35 to 300 parts by mass, an amount of the colloidal silica (C) is 80 parts by mass or more and 600 parts by mass or less, and an amount of the water (E) is 650 parts by mass or more relative to 100 parts by mass of the copolymer (A). Claim: 2. The antifoggant composition according to claim 1, wherein an amount of the monomer (a-1) is 20 to 90 parts by mass, an amount of the monomer (a-2) is 5 to 50 parts by mass, and an amount of the monomer (a-3) is 1 to 40 parts by mass in 100 parts by mass of a total of the monomer (a-1), the monomer (a-2), and the monomer (a-3). Claim: 3. The antifoggant composition according to claim 1 or 2, wherein an amount of the surfactant (D) is 1 to 35 parts by mass relative to 100 parts by mass of the copolymer (A). Claim: 4. The antifoggant composition according to any one of claims 1 to 3, wherein the monomer mixture further contains a (meth)acrylate monomer (a-4) having a hydroxyl group represented by General Formula (4): [chemical expression included] (wherein R7 is a hydrogen atom or a methyl group, and R8 is a linear or branched alkylene group having 1 to 8 carbon atoms) and/or a (meth)acrylamide monomer (a-5) having a hydroxyl group represented by General Formula (5): [chemical expression included] (wherein R9 is a hydrogen atom or a methyl group, and R10 is a linear or branched alkylene group having 1 to 8 carbon atoms.). Claim: 5. The antifoggant composition according to claim 4, wherein an amount of the monomer (a-4) and/or the monomer (a-5) is 30 parts by mass or less relative to 100 parts by mass of a total of the monomer (a-1), the monomer (a-2), and the monomer (a-3). Claim: 6. The antifoggant composition according to any one of claims 1 to 5, wherein the blocked polyisocyanate curing agent (B) is a (meth)acrylate polymer and/or copolymer having a blocked isocyanate group. Claim: 7. The antifoggant composition according to any one of claims 1 to 6, wherein the blocked polyisocyanate curing agent (B) is a (meth)acrylate copolymer obtained from a monomer mixture containing an N,N-dialkyl (meth)acrylamide monomer (b-1) represented by General Formula (6): [chemical expression included] (wherein R11 is a hydrogen atom or a methyl group, and R12 and R13 are independently a linear or branched alkyl group having 1 to 8 carbon atoms); a (meth)acrylate monomer (b-2) having a blocked isocyanate group represented by General Formula (7): [chemical expression included] (wherein R14 is a hydrogen atom or a methyl group, and R15 is a residue derived from a blocking agent); and a (meth)acrylate monomer (b-3) having a hydrocarbon group represented by General Formula (8): [chemical expression included] (wherein R16 is a hydrogen atom or a methyl group, and R17 is a linear, branched, or cyclic hydrocarbon group having 1 to 22 carbon atoms.). Claim: 8. The antifoggant composition according to claim 7, wherein an amount of the monomer (b-1) is 20 to 90 parts by mass, an amount of the monomer (b-2) is 5 to 50 parts by mass, and an amount of the monomer (b-3) is 1 to 40 parts by mass in 100 parts by mass of a total of the monomer (b-1), the monomer (b-2), and the monomer (b-3).
