The absorbent article according to claim 1, comprising a second auxiliary adhesive disposed between the second substrate and the layer of second superabsorbent polymer particles. 11. The absorbent article according to claim 1, wherein the first superabsorbent polymer particles and the second superabsorbent polymer particles are made of different materials. 12. The absorbent article according to claim 11, wherein the first superabsorbent polymer particles have a lower Urine Permeability Measurement than the second superabsorbent polymer particles. 13. The absorbent article according to claim 1, wherein the mixed layer comprises a homogeneous mix of first superabsorbent polymer particles and cellulosic fibers, and wherein the mixed layer comprises from 10% to 70% of the first superabsorbent polymer particles by total weight of the mixed layer. 14. The absorbent article according to claim 1, wherein the basis weight of the mixed layer is uniform across the area of deposition of the first absorbent layer. 15. The absorbent article according to claim 1, wherein at least one of the layer of second superabsorbent absorbent polymer particles and the mixed layer are deposited in a non-rectangular deposition pattern on their respective substrate. 16. The absorbent article according to claim 1, wherein the deposition area of the layer of the second superabsorbent polymer particles is smaller than the deposition area of the mixed layer. 17. The absorbent article according to claim 1, comprising an acquisition layer or acquisition system between the topsheet and the absorbent core. 18. The absorbent article according to claim 17, wherein the acquisition layer or system comprises at least one layer comprising cross-linked cellulose fibers.
