Abstract
Fragrances having a fresh character are usually very volatile and therefore not very economical in typical applications such as washing or cleaning processes for example. For that reason they have to be used in relatively large amounts in order to bring about appropriate effects. The present invention describes photolabile pro-fragrances of formula (I) that allow for a greatly improved persistence of the fragrance impression, in particular one having a fresh character, in typical applications. Said pro-fragrances attach very readily to target substrates, such as textiles for example. A more economical use of the fragrances in question can be ensured in this way.
