FIELD: household chemical goods. ^ SUBSTANCE: invention provides composition for applying self-oxidizing architectural coating, which is suitable for handling by inexperienced users having no personal respiratory protection devices at ambient temperatures and natural day light. Composition contains self-oxidizing polymeric binder and promoter system to promote self-oxidation of the binder, which promoter contains from 0 to 0.01 wt % cobalt ions and metal ions other than cobalt ions promoting surface self-oxidation in amount 0.001 to 0.04 wt % and those promoting bulk self-oxidation in amount 0.5 to 2 wt %, and also at least one photoinitiator in amount 0.3 to 2 wt %, all based on the weight of binder. This composition is applied onto surface to obtain dried architectural coating irradiated by low-energy radiation in the form of light with wavelength between 350 and 650 nm. Composition removes need of utilizing larger than trace amounts of cobalt ions, which are considered to be carcinogenic, and ensures achievement of suitably high self-oxidation rates. No cobalt utilization is preffered. Utilization of low concentrations of other metal ions leads to reduction in composition color variation, often al levels lower than those achieved when utilizing common cobalt promoters. ^ EFFECT: avoided need of high-energy irradiation |
