Bleaching composition for dry cleaning containing transition metal bleach catalyst

A bleaching composition comprising:

• a) from 0.05 microM to 50 mM of a complex comprising an organic substance which forms the complex with a transition metal, the complex having the general formula (A1):
• [MaLkXn]Ym (A1)
• in which:
• M represents a metal selected from Mn(II)-(III)-(IV)-(V), Cu(I)-(II)-(III), Fe(I)-(II)-(III)-(IV), Co(I)-(II)-(III), Ni(I)-(II)-(III), Cr(II)-(III)-(IV)-(V)-(VI)-(VII), Ti(II)-(III)-(IV), V(II)-(III)-(IV)-(V), Mo(II)-(III)-(IV)-(V)-(VI), W(IV)-(V)-(VI), Pd(II), Ru(II)-(III)-(IV)-(V) and Ag(I)-(II);
• L represents a ligand, or its protonated or deprotonated analogue;
• X represents a coordinating species selected from any mono, bi or tri charged anions and any neutral molecules able to coordinate the metal in a mono, bi or tridentate manner;
• Y represents any non-coordinated counter ion;
• a represents an integer from 1 to 10;
• k represents an integer from 1 to 10;
