PCT No. PCT/EP96/00443 Sec. 371 Date Aug. 5, 1997 Sec. 102(e) Date Aug. 5, 1997 PCT Filed Jan. 31, 1996 PCT Pub. No. WO96/24385 PCT Pub. Date Aug. 15, 1996The disclosure relates to a process for the treatment of a surface with a hygiene agent which can include the steps of: a) providing at the surface a non-photochemical catalyst (such as a transition metal compound) which catalyses the formation of the hygiene agent from one or more precursors, whereby the catalyst becomes deposited at the surface, and, b) subsequently treating the surface with a treatment agent (such as a solution of hydrogen peroxide) having the or each hygiene agent precursor, such that the hygiene agent is generated at the surface. The disclosure also provides a process which includes the step of treating the surface which has a non-photochemical catalyst bound thereto with a treatment agent having at least one hygiene agent precursor which forms said hygiene agent in the presence of the catalyst and, a process for the manufacture of an article which includes the step of incorporating therein, at the time of manufacture, a non-photochemical catalyst capable of transforming at least one hygiene agent precursor into a hygiene agent. |
