PURPOSE:To reduce change in curability and the physical properties of cured articles caused by an ambient atmosphere during curing and to improve the storage stability of curing products, by blending a polymer having SH groups with two specified dithiocarbamic acid metal chelate compds. as curing catalysts in combination. CONSTITUTION:100pts.wt. polymer having SH groups is blended with 0.001-10 pts.wt. at least one compd. (A) selected from among the following compds. and 0.001-10pts.wt. at least one compd. (B) selected from among the following compds. A: dithiocarbamic acid metal chelate compds. of formula I or II (wherein R<1>, R<2> are each H, a 1-18C hydrocarbon group; R<3> is a 1-18C hydrocarbon group; x is 1, 2, 3, 4; M<1> is a metal selected from among Groups VIIb and VIII metals of the periodic table). B: dithiocarbamic acid metal chelate compds. of formula III or IV (wherein R<4>, R<5> are each H, a 1-18C hydrocarbon group; R<6> is a 1-18C hydrocarbon group; y is 1, 2, 3, 4; M<2> is a metal selected from among Groups Ia, Ib, IIa, IIb, IIIa, IVa, VIa and VIb of the periodic table).
