G03F 7/20
G03F 7/42

US Classification:

4302701, 430926, 430138, 430256, 430258, 430259, 430262, 430263, 430329, 430332, 430336, 430337, 430340, 430343, 430346, 430356, 430358, 430359, 430363, 430367, 430372, 430428, 430541, 430339, 430374, 430962, 430338, 522 63, 522 65, 522 68

Abstract:

Imaging compositions and methods of using the compositions are disclosed. The imaging compositions are sensitive to low levels of energy such that upon application of the low levels of energy the compositions change color or shade. The compositions may be applied to a work piece to mark it and removed from the work piece by peeling.
