Abstract
Soap composition having improved imaging properties. The composition comprises (1) at least one metal cation which produces an image when reacted with by a dye precursor which is a derivative of dithiooxamide, (2) at least one rosin soap, and (3) at least one metallic soap. The presence of the metallic soap results in a higher level of metal cation available for image formation, thus improving speed of image formation and image quality.
