ABSTRACT:
A resin composition includes a dicyclopentenyl-group containing unsaturated polyester resin, a phenothiazine derivative (a) and an anion producing compound (b). On the other hand, resin composition includes a thermosetting resin, a phenothiazine derivative (a), an anion producing compound (b) and a phosphorous ester (c). A manufacturing method of resin composition includes the step of obtaining a dicyclopentenyl-group-containing unsaturated polyester by polycondensing unsaturated polyester material including a compound having a dicyclopentenyl group, and the step of mixing a cross-linking monomer with the obtained dicyclopentenyl-group-containing unsaturated polyester, wherein the phenothiazine (a) and the anion producing compound (b) are added in at least one of those steps. This provides the resin composition which produces no gel during storage and has very little gel time drift and viscosity drift, and moreover which produces a cured product of good hue, water resistance and surface drying characteristics, and further provides the manufacturing method of such resin composition.
