ABSTRACT:
Imaging layers, image recording media, and methods of preparation of each, are provided. One exemplary embodiment of the imaging layer, among others, includes a matrix, a radiation absorbing compound dissolved in the matrix, at least two activators substantially dissolved in the matrix, and a color former. The activators can include a primary activator having a higher acidity than a secondary activator. In addition, the primary activator has a lower solubility in the matrix than the secondary activator. The color former is substantially insoluble in the matrix at ambient conditions and is substantially uniformly distributed in the matrix.
