Abstract: Dye transfer inhibiting systems are disclosed, comprising an enzyme exhibiting peroxidase activity, a hydrogen peroxide source, an additional oxidizable substrate, and an accelerator preferably having the formula ##STR1## Detergent compositions free of linear alkylbenzenesulfonate containing the dye transfer inhibition system and typical detergent ingredients are also disclosed. More effective and efficient dye transfer inhibition of fugitive dyes is achieved by using the dye transfer inhibition system as a detergent additive or in a detergent composition matrix free of linear alkylbenzenesulfonate.

Abstract: An electroless plating bath composition is produced by mixing stannous oxide, at least one member selected from the group consisting of lead oxide and lead perchlorate, perchloric acid, and thiourea. The composition thus obtained is ideal for electroless plating of a substrate of copper, particularly a substrate provided with a resist film.
