Imaging layers 14, image recording media 10, and methods of preparation of each, are provided. One exemplary embodiment of the imaging layer 14, among others, includes a matrix 16, a radiation absorbing compound dissolved in the matrix 16, at least two activators substantially dissolved in the matrix 16, 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 16 than the secondary activator. The color former is substantially insoluble inthe matrix 16 at ambient conditions and is substantially uniformly distributed in the matrix 16. |
