Classification: CPC C  A | IPC A  C

Claim 25:
26. A method for making an antimicrobial coating material, comprising mixing
(i) polymer particles with their surfaces covered with positive charges, wherein the polymer particles comprise a copolymer containing structural units derived from a cationic polymerization initiator and a monomer containing a carbon-carbon double bond, with
(ii) a resin, and
(iii) a solvent to produce an antimicrobial coating material,
wherein the cationic polymerization initiator is a compound having a chemical structure of general formula (I):, , wherein,
Y represents a single bond;
Z represents a single bond;
R72, R73, R75, R76, R77, and R78 are each independently selected from the group consisting of hydrogen atom and C1-6 alkyl;
R81, R82, R83, and R84 are each independently a C1-4 alkyl group;
R71 and R74 are each independently a C1-3 alkyl group; and
Xf− is a counter anion.
