A developer sheet having reduced tack useful in forming reproductions having a controllable gloss finish or in forming transparencies is provided. The developer sheet has a support with a layer on the surface of the support of a finely divided thermoplastic developer material and a non-reactive, non-scattering pigment. The developer material is capable of reacting with a color precursor to produce a visible image while the pigment reduces tack. Both the developer material and the pigment are capable of forming an essentially transparent film upon the application of heat and/or pressure.
