ABSTRACT:
The present invention provides a developer sheet useful in forming reproductions having a controllable gloss finish and reduced photolytic yellowing. The developer sheet comprises a support having a layer of a finely divided, thermoplastic, phenolic developer material and an anti-yellowing agent on the surface thereof. The phenolic developer material is capable of reacting with a color former to produce a visible image and is capable of coalescing into a thin film which imparts gloss to the image upon the application of heat.
