The present invention relates to the technical field of composite materials comprising a thermosetting polymer matrix in which thermoplastic polymer and/or elastomer particles are dispersed. More precisely, the invention relates to a novel type of polymeric material obtained by using a particular ionic liquid as cross-linking agent for an epoxy resin mixed with a thermoplastic polymer and/or an elastomer. The invention also relates to a process for manufacturing said composite material and uses thereof, notably in the aeronautical, aerospace, automotive, maritime, wind power, electronics, or sports and leisure sectors.

A three-dimensional printing kit can include a build material with from about 80 wt % to 100 wt % polymeric particles having a D50 particle size from about 10 ?m to about 150 ?m, and a fusing agent including from about 0.5 wt % to about 20 wt % avobenzone particles dispersed in an aqueous liquid vehicle based on a total weight of the fusing agent.
