A process for preparing pressure-sensitively adhesive polyacrylates by free-radical addition polymerization, characterized in that mercapto-functionalized photoinitiators of the general formula (I) and/or (II). H-S-R (I) R-S-S-R' (II) are added to the monomer mixture or to the reaction mixture, R and R' being chosen independently of one another from the following groups: a) benzophenone, acetophenone, benzil, benzoin, hydroxyalkylphenone, phenylcyclohexyl ketone, anthraquinone, thioxanthone, triazine, or fluorenone radicals, it being possible for each of these radicals to be substituted by one or more halogen atoms and/or one or more alkoxy groups and/or one or more amino groups or hydroxyl groups, b) radicals which comprise one or more of the substituted or unsubstituted radicals specified under a).
