The invention discloses a scratch-resistant high-gloss spraying-free polypropylene composition with aesthetic effect. The composition comprises the following components by weight percent: 40-94wt% of polypropylene, 0-15wt% of polyethylene, 0-20wt% of elastomer, 0-30wt% of filler, 1-6wt% of a scratch resistant agent system, 2-6wt% of effect pigment, 0.1-2wt% of brightener, and 0-4wt% of a compatilizer. Due to the synergistic effect of the scratch resistant agent system and the effect pigment, the spraying-free product is endowed with more excellent scratch resistance, thus having broader application prospect; in addition, the fluidity of the polypropylene composition is also affected, so that in injection molding or extruding, the change of the space position of the metal pigment of certain appearance shape along with melt flow is limited, the orientation of the metal pigment along with melt flow is reduced or even avoided, the defect of heterochromia of traditional spraying-free product ...
