Mold-preventing air filter filtration medium and mold-preventing air filter

A mold-preventing air filter filtration medium,

• wherein the filtration medium is loaded with a water-retaining macromolecule polymer, a mold-preventing agent and a binder resin, and
• wherein the water-retaining macromolecule polymer is a copolymer of a phosphorylcholine-like group containing monomer and a hydrophilic monomer having at least one trialkylamino base,
• wherein the water-retaining macromolecule polymer and the mold-preventing agent are combined in a solid weight ratio of 1:10-500, and
• wherein the phosphorylcholine-like group containing monomer is represented by the following formula (1)
• wherein X represents a divalent organic residue,
• wherein Y represents an alkyleneoxy group having 1-6 carbon atoms,
• wherein Z represents a hydrogen atom or R5-O—(C═O)—
• wherein R5 represents an alkyl group having 1-10 carbon atoms or a hydroxyalkyl group having 1-10 carbon atoms,
• wherein R1 represents a hydrogen atom or a methyl group,
• wherein R2, R3, and R4 are the same or different, and represent a hydrogen atom or an alkyl or hydroxyalkyl group having 1-6 carbon atoms,
• wherein m represents 0 or 1, and
• wherein n is an integer of 1-4.
