  We study the elasto-plastic behavior of dense attractive emulsions under
mechanical perturbation. The attraction is introduced through non-specific
depletion interactions between the droplets and is controlled by changing the
concentration of surfactant micelles in the continuous phase. We find that such
attractive forces are not sufficient to induce any measurable modification on
the scalings between the local packing fraction and the deformation of the
droplets. However, when the emulsions are flown through 2D microfluidic
constrictions, we uncover a measurable effect of attraction on their
elasto-plastic response. Indeed, we measure higher levels of deformation inside
the constriction for attractive droplets. In addition, we show that these
measurements correlate with droplet rearrangements that are spatially delayed
in the constriction for higher attraction forces.
