Method for the formation of a heat mode image

Abstract

A new method is disclosed for the formation of a heat mode image comprising exposing to a heat pattern a donor element comprising a reactant (A) while in contact with an acceptor element comprising a reactant (B), the said reactant (A) being transferred by said exposure from said donor element to said acceptor element to form an image therein by reaction of said reactant (A) with said reactant (B), (2) separating said donor and said acceptor element from each other, and (3) optionally giving said acceptor element a post-treatment consisting of a supply of extra energy, characterized in that the said acceptor element comprises spacing particles also containing a said reactant (B), and/or the said donor element comprises spacing particles also containing a said reactant (A), or a said reactant (B), or a density providing compound, preferably carbon black, or combinations thereof. In the preferred embodiment reactant (A) is a reducing agent and reactant (B) is an organic silver salt, preferably silver behenate. In this case a heat post-treatment on the separated acceptor is performed. The heat pattern is preferably generated by laser exposure.
