Abstract
Disclosed are a gradient resin, a preparation method therefor and the use thereof. The gradient resin of the present application is formed by fusing different layers with color transition changes, wherein the color transition change between the two adjacent layers is in the range of 0.1% to 20%. The gradient resin is composed of, by mass percentage, 98%-99.99% of a resin powder and 0.01%-2% of a pigment.
