Composition containing two or more components comprises at least a (meth)acrylate; diketo group (I); at least a metal- salt or -complex, where the metal is a transition metal and at least a peroxide, perester or a hydrogen peroxide; where the first component comprises the metal salt or complex and the second component comprises the peroxide, perester or hydrogen peroxide. Composition containing two or more components comprises at least a (meth)acrylate; diketo group (I) of formula (R 1>-(C(=O)-CH(R 3>)-C(=O)-R 2>) n); at least a metal- salt or -complex, where the metal is a transition metal and at least a peroxide, perester or a hydrogen peroxide; where the first component comprises the metal salt or complex and the second component comprises the peroxide, perester or hydrogen peroxide. n : 1-20, preferably 1-6; R 1>organic compound with n valency; either R 2>, R 3>optionally substituted (cyclo)alkyl, aryl or aralkyl; or R 2>R 3>a ring optionally with heteroatoms or OR 4>; and either R 4>optionally substituted (cyclo)alkyl, aryl or aralkyl; or R 4>R 3>a ring optionally with heteroatom. Independent claims are included for: (1) cured composition obtained by curing the composition in air; (2) a coated article obtained by mixing the composition, coating the composition on a substrate (S1) and hardening the mixture in air; and (3) agglutinated article and sealed article obtained by mixing the composition, coating the mixture on S1, contacting the surface of the S1 with another substrate (S2) and hardening the obtained composition. |
