Color resistance transference means colored plastic products and other state of solid, liquid, gas and other substances long-term contact or work in a specific environment, possible and the material physical or chemical effect, show the pigment from plastic internal migration to the products of free surface, or migrate to the adjacent plastic or solvents.

Pigments in the pigment of transference and plastic material of the molecular chain of the tightness of the rigid and related. When in the plastic plasticizer dosage increased, the molecular distance increased, more loose structure, thereby reducing the interaction of the polymer chains, so that the pigment migration rate increased. Especially when soft PVC color, choose paint more attention should be paid to.
