Abstract
Imaging layers, optical disks, and methods of preparation of each, are disclosed.
Claims15
An optical disk comprising:
- a substrate having a first side and a second side, wherein the first side stores digital data, wherein the second side includes an imaging layer, wherein the imaging layer includes:
- a matrix including a monoacrylate and a diacrylate, wherein the monoacrylate is about 13 to 45 wt % of the imaging layer, wherein the diacrylates is about 2 to 33 wt % of the imaging layer;
- a radiation-absorbing compound, wherein the radiation-absorbing compound has a solubility of at least 2% by weight in the matrix;
- an activator;
- and
- a color former.
3 more elements
A method for preparing an optical disk including an imaging layer, the method comprising:
- providing a matrix including a monoacrylate and a diacrylate, wherein the monoacrylate are about 13 to 45 wt % of the imaging layer, wherein the diacrylates are about 2 to 17 wt % of the imaging layer;
- mixing the radiation-absorbing compound, the activator, and the color former, in the matrix to form a matrix mixture, wherein the radiation-absorbing compound has a solubility of at least 2% by weight in the matrix;
- and
- disposing the matrix mixture onto a substrate to form the imaging layer.
