When Courtelle is pretreated with oxidising agents, e. g. hydrogen peroxide, sodium hypochlorite, peracetic acid and permono–sulphuric acid, subsequent thermal discoloration takes place more rapidly. Hydrofluoroboric acid pretreatment retards discoloration, but the effect is not fast to washing, although fastness to cold water is obtainable by using a combination of ammonia and hydrofluoroboric acid.
