A composition comprising an inorganic persalt and an oxygen-releasing compound represented by the formula:
- ##STR3## Wherein R.sub.1 is selected from the group consisting of hydrogen and straight or branched chained alkyl groups having from the group consisting of 1 to 6 carbon atoms, R.sub.2 is selected from straight or branched chain alkyl groups having from about 1 to about 12carbon atoms and R.sub.3 is selected from the group consisting of straight or branched chain alkyl groups having from about 1 to about 3 carbon atoms.
A method of bleaching articles which comprises contacting said articles with a composition comprising an inorganic persalt and an oxygen-releasing compound represented by the formula:
- ##STR4## wherein R.sub.1 is selected from the group consisting of hydrogen and straight or branched chain alkyl groups having from 1 to about 6carbon atoms, R.sub.2 is selected from the group consisting of straight or branched chain alkyl groups having from about 1 to about 12 carbon atoms and R.sub.3 is selected from the group consisting of straight or branched chain alkyl groups having from about 1 to about 3 carbon atoms.
