Zusammenfassung:	A curable composition and method for making hollow shell molds, such as those employed to make hearing aids. The curable composition includes a (meth)acryl functionalized curable component, a cure system, a pigment composition, and a dispersion stabilizing additive. The pigment composition includes at least one pigment disbursed within the curable composition. The dispersion additive maintains the pigment in a disbursed form prior to cure. The dispersion additive includes an alkali metal cation and a reaction product.
