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.
Claims23
An imaging layer comprising:
- a matrix;
- a radiation absorbing compound dissolved in the matrix;
- at least two activators substantially dissolved in the matrix, wherein a primary activator has a higher acidity than a secondary activator, and wherein the primary activator has a lower solubility in the matrix than the secondary activator;
- and
- a color former that is substantially insoluble in the matrix at ambient conditions and is substantially uniformly distributed in the matrix.
An image recording medium comprising:
- a substrate having a two-phase layer disposed thereon, wherein the two-phase layer includes:
- a matrix,
- a radiation absorbing compound dissolved in the matrix,
- at least two activators substantially dissolved in the matrix, wherein a primary activator is a highly acidic phenol compound and a secondary activator is a low acidic phenol compound, and
- a color former that is substantially insoluble in the matrix at ambient conditions and is substantially uniformly distributed in the matrix.
A method for preparing an imaging material, the method comprising:
- providing a matrix, a radiation absorbing compound, a color former, and at least one activator, wherein the activator includes a primary activator and a secondary activator, wherein the primary activator has a lower solubility in the matrix than the secondary activator;
- dissolving the radiation absorbing compound, the primary activator, and the secondary activator, substantially in the matrix;
- and
- distributing the color former substantially uniformly in the matrix, wherein the color former is substantially insoluble in the matrix at ambient conditions.
An imaging means, the means comprising:
- means for absorbing energy;
- means for forming color;
- at least one activator, wherein the activator includes a primary activator that is a highly acidic phenol compound and a secondary activator that is a low acidic phenol compound;
- and
- means for binding the means for absorbing energy and the primary and secondary activators, wherein the means for absorbing energy and the primary and secondary activators are substantially dissolved in the means for binding, wherein the means for forming color is substantially insoluble in the means for binding at ambient conditions, and wherein the means for forming color is substantially uniformly distributed in the means for binding.
