Procedure

The APC (1 ml) was added to a freshly prepared dispersion of microcapsules A4 or E10 (each 0.012 mmol with respect to the total amount of fragrance to be released). The sample was then diluted by adding demineralized tap water (9 ml). Reference samples, containing either 2-phenylethyl 2-oxo-2-phenylacetate or decyl 2-oxo-2-phenylacetate as the corresponding non-encapsulated pro-fragrance of formula (I) from the prior art (WO 99/60990, obtained as described in Example 1) or unmodified 2-phenylacetaldehyde or decanal (each 0.012 mmol) were prepared in the same way. The samples were then deposited as a film onto a porous ceramic plate (ca. 5×10 cm) by carefully pipetting sample (0.75 ml) onto the surface of the substrate. The samples were then covered with a crystallizing dish (2 l) and exposed to ambient indoor daylight at room temperature.
