摘要：
A self-contained sheet for forming an image comprising a support, a first layer of microcapsules containing a color precursor of the electron donating type in a carrier liquid on the surface of the support, a layer of microspheres overlying the microcapsule layer, and a developer material present in at least one of the microcapsule layer or microsphere layer, wherein the developer material can react with the color precursor to form a visible image when the color precursor is released from the microcapsules.
