The invention discloses a PC/ABS material composition for relieving the yellow discoloration, which is prepared from the following ingredients in percentage by weight: 10 to 60 parts of acrylonitrile-butadiene-styrene graft copolymers, 30 to 85 parts of polycarbonate, 0 to 10 parts of acrylics graft rubber, 0.25 to 0.88 parts of coloring agents, 0 to 1 part of antioxidizers and 0 to 1 part of light stabilizers. Yellow dyes without light illumination resistance performance exist in a dye system, and the dyes can not influence the whole coloring process of plastics in the plastic coloring process, but in the light illumination process, the dyes gradually fade, the PC/ABS materials carry out yellow discoloration in the light illumination process, so the two mutually inconsistent processes have the mutual counteraction effect, and the color aberration of the whole PC/ABS composition is reduced after the light illumination. At the same time, the mechanical property of the composition material is not obviously reduced.
