<P>PROBLEM TO BE SOLVED: To provide an antibacterial and antifungal agent having sufficient antibacterial and antifungal properties, excellent water-proofing property, resistance against thermal discoloring and resistance against BHT (Butylated HydroxyToluene)/NOx gas discoloring. <P>SOLUTION: The antibacterial and antifungal agent contains a cationic polymer represented by general formula (1) and having a weight average molecular weight of 1,000 or more. In general formula (1), R<SP POS="POST">1</SP>represents a hydrogen atom, an alkyl group, a hydroxyalkyl group or an alkenyl group; R<SP POS="POST">2</SP>represents an oxyalkylene group represented by general formula (2); R<SP POS="POST">3</SP>represents an alkylene group; R<SP POS="POST">4</SP>represents a hydrogen atom, an alkyl group, a hydroxyalkyl group or an alkenyl group; Y represents an oxygen atom or a sulfur atom; n represents a positive integer; and X<SP POS="POST">m-</SP>represents an m-valent anion. In general formula (2), R<SP POS="POST">5</SP>represents an alkylene group; and a and b each represent an integer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
