Briefly described, embodiments of this disclosure include light directed imaging layers, light directed image recording media, and methods of preparation of each. One exemplary embodiment of the light directed imaging layer, among others, includes a matrix; a developer substantially dissolved in the matrix; a color former that is substantially insoluble in the matrix at ambient conditions and is substantially uniformly distributed in the matrix; and a pigment antenna uniformly distributed in the matrix, wherein the pigment antenna has the characteristic of absorbing an imaging radiation, and wherein the pigment antenna has a diameter less than the wavelength of the imaging radiation.

A radiation image-able coating includes a first phase including a radiation curable polymer matrix and an activator disposed in the radiation curable polymer matrix, a second phase insolubly distributed in the first phase, the second phase including a color-former, and a hybrid antenna dye package distributed in at least one of the first and second phase, wherein the hybrid antenna dye package includes at least a first antenna dye having a high extinction coefficient and a second antenna dye having a low extinction coefficient.
摘要:
For each of a number of regions of a label surface of a substrate that are to be optically written to form a human-readable image, a corresponding power level at which an optical beam is to impinge the region to optically write a desired mark to the region as part of the image is determined. The optical beam impinges the region by being switched on and off from a higher power level to a lower power level to achieve the corresponding power level on average. At least one of the following are adjusted: a number of times the optical beam is switched on and off, a length of time the optical beam remains on each time it is switched on, and a duty cycle of the optical beam while the optical beam is positioned over the region.
