Abstract

A novel latent image receiving sheet is disclosed comprising a substrate bearing microcapsules having walls of thermosetting resin. The walls of the microcapsules have an elongation less than 1 %, and the image receiving sheet or microcapsules are resistant to heat.
Surprisingly, the latent image receiving sheet capsules nonetheless rupture upon application to the record material of a point source energy input or pulse comprising a .DELTA.T of at least 115°C per one millisecond.
