Abstract: A three-dimensional printing kit can include a polymeric build material including from about (80) wt% to (100) wt% polymer particles having an average particle size from about (10) µm to about (150) µm, and can also include a fusing agent including an aqueous liquid vehicle and from about (2) wt% to about (20) wt% of a mixture of organic dye radiation absorbers. The mixture of organic dye radiation absorbers can include a charged yellow water-soluble organic dye and a cyan water-soluble organic dye. The mixture of the organic dye radiation absorbers can be from about (1) wt% to about (40) wt% soluble in water.
