PROBLEM TO BE SOLVED: To provide a method for long-term preservation of radically polymerizable resin composition that can prevent the occurrence of the gel-time drifting phenomenon during the storage and can maintain the curing performance. SOLUTION: In this method for long-term preservation of a radically polymerizable resin composition, a cobalt compound and N,N'-dimethylacetoacetamide are added to a radically polymerizable resin composition including a radically polymerizable resin and a curing agent. At this time, the amount of the N,N'-dimethylacetoacetamide is kept at 0.01 to 0.18 pt.wt. per 100 pts.wt. of the radically polymerizable resin. COPYRIGHT: (C)2007,JPO&INPIT
