ABSTRACT:
Provided are a resin composition improved in utilization of active compound by controlling the bleeding of the active compound low in vaporizability and a molded product obtained from the resin composition. The resin composition comprises 100 parts by weight of a resin, 0.01-200 parts by weight of an active compound and 0.1-100 parts by weight of a vaporizable plasticizer having a vapor pressure of 0.001 mmHg or higher at 20.degree. C., and the vapor pressure (P1) of the vaporizable plasticizer at 20.degree. C. and the vapor pressure (P2) of the active compound at 20.degree. C. satisfy the formula: P1/P2.gtoreq.2.
