Abstract
Accelerator solution suitable for forming a redox system with peroxides, comprising (i) a compound of a first transition metal selected from manganese and copper, (ii) a compound of a second transition metal; the weight ratio of first transition metal:second transition metal being in the range 3:1 to 200:1, (iii) a nitrogen-containing base, and (iv) a hydroxy-functional solvent, with the proviso that the accelerator solution does not contain ascorbic acid.
