The effect of antiozonants on the reaction between dyes and ozone has been investigated. The antiozonant effect was found to increase the greater the agent's reactivity with ozone. The antiozonant also reacted with radicals produced by the homolytic cleavage of the substrate‐ozone adducts. The effect of the added antiozonant generally increased in the order 2, 6‐di‐t‐butylphenol < α‐tocopheral, dibutylthiourea < N‐isopropyl‐N′‐phenyl‐p‐phenylendiamine ≅ nickel dibutyl‐dithiocarbamate.
