PROBLEM TO BE SOLVED: To provide a paste-like polymerizable composition that is prepared by mixing two or three pastes and polymerized and that does not undergo gelation and has polymerization cure time kept stable in case where the pastes have been stored for a long period of time before subjected to polymerization. SOLUTION: The paste-like polymerizable composition comprises a first paste comprising (a) a (meth)acrylate having at least one unsaturated double bond, (b) a filler and (c) a pyrimidine trion derivative, a second paste comprising (a) a (meth)acrylate having at least one unsaturated double bond, (b) a filler, (d) an organic halogen compound and (e) an organic metal compound or a third paste comprising (a) a (meth)acrylate having at least one unsaturated double bond, (b) a filler and (d) an organic halogen compound, and a fourth paste comprising (a) a (meth)acrylate having at least one unsaturated double bond, (b) a filler and (e) an organic metal compound.
