Photosensitive microcapsules

A photosensitive microcapsule comprising

• a. a core material comprising a benefit agent;
• and
• b. a shell comprising a photosensitive polymer;
• wherein the photosensitive polymer comprises a photosensitive moiety comprising a structure selected from the group consisting of
• and combinations thereof;
• wherein R5 is selected from alkyl, substituted alkyl, alkoxy, substituted alkoxy, carboxy, carboxyl, substituted carboxyl, aryl, substituted aryl, or a carbon atom of a polymer backbone;
• wherein R6 and R9 comprise a 1,3 dione moiety;
• wherein the photosensitive moiety is incorporated in a monomer that is polymerized to form the photosensitive polymer, wherein the monomer is selected from the group consisting of:
