Additive manufacturing compositions and methods may include a resin stabilized pigment. The pigment may be easily combined with at least one component of a co-reactive system, such as a co-reactive prepolymer formulation, via solid mixing without the need for grinding or additional solvents. The prepolymer formulation may be pigmented, printed, and cured under ambient conditions, and one or more pigments may be incorporated into the composition to change the color of the composition during printing and/or to selectively change the color of the printed article among several colors.

There is described a method for the production of a functional polyester having functional group X. The method comprises the step of melt blending a composition comprising (i) a high number average molecular weight (Mn) polyester having a Mn of ≥6,000 Da; and (ii) a functional compound comprising functional group Y which may be the same as functional group X or be different to functional group X but be operable to form functional group X in the functional polyester. The composition is melt blended such that the high Mn polyester and the functional compound react to produce the functional polyester. The high Mn polyester has a Mn that is higher than the Mn of the functional compound. The present invention extends to functional polyesters produced by the method; aqueous, solventborne and powder coating compositions containing the functional polyester, and articles coated with the said coating compositions.
