That is, 2,2,6,6-tetramethyl-4-piperidyl methacrylate has a piperidine ring, and the nitrogen atom on the piperidine ring is a secondary amine, so it is a basic compound. Therefore, when a dispersion in which a polymer obtained by polymerizing a monomer component containing this compound is dispersed in an aqueous dispersion medium is exposed to acidic conditions, the nitrogen atom on the piperidine ring in the polymer reacts with the acid to form a salt. The dispersion is prone to aggregation due to coagulation caused by the salt thus formed.
