Abstract
The present invention is directed to an improved copper plating bath for depositing a copper layer onto a printing cylinder, the copper plating bath comprising: (a) a source of copper ions; (b) a source of methane sulphonate ions; (c) a source of chloride ions; (d) an organosulphur compound having the formula R—S—R'—SOXor X—OS—R′—S—R—S—R′—SO—X, wherein R is alkyl, hydroxyalkyl or alkyl ether, R′ is a C–Calkyl group, and Xis a cation; and (e) a polyether compound and method of using the same. The copper plating bath produces a plating deposit that has a stable hardness and is free from self-annealing during high speed plating.
