    摘要： A method and a medium for laser imaging is herein disclosed. The medium incorporates one or more types of microstructures having a predetermined heat or radiation modifiable optical characteristic such as color, scattering, diffusion, diffraction, interference and iridescence. Associated intimately with the microstructures is a radiation antenna that acts to absorb radiation from a radiation source. The radiation antenna and source are attuned to one another to efficiently transfer energy therebetween and subsequently to the microstructures; this transfer of energy results in the modification of an optical characteristic of the microstructures to form an image on the medium. The medium has one or more layers that may include both the radiation antenna and the microstructures. Alternatively, the microstructures and radiation antenna may be included in separate layers. Coatings that incorporate one or more layers that include distinct microstructures and radiation antennae are also contemplated.

    摘要： Substrates, coatings and methods for marking substrates using the coatings. The substrate contains a coating of encapsulated marking materials. Capsules of the encapsulated marking materials are designed to preferentially absorb a predetermined wavelength of light or range of wavelengths of light. The capsules contain color chemistry capable of activation by the predetermined wavelength of light or range of wavelengths of light for the generation of a color response. By utilizing capsules of differing color chemistries, such substrates are capable of multi-color image generation.

    摘要： Compositions and methods for production of color images which are developable at desired wavelengths are disclosed and described. The color forming composition can include a color former which is a spiro dye. The color forming composition can include a radiation antenna admixed with or in thermal contact with the color former. The color forming composition can also be optimized for development using electromagnetic radiation having a selected development wavelength. The color forming compositions are useful in forming images on a wide variety of substrates such as optical disks.

    摘要： A method and apparatus are provided for visually marking a recording medium by inducing a phase change in a light-sensitive surface by heat absorption from laser radiation. The method includes applying the laser radiation to a desired portion of the light-sensitive surface according to a first power profile for a first period sufficient to substantially obtain a color change at the desired portion, and applying the laser radiation to the desired portion of the light-sensitive surface according to a second power profile for a second period sufficient to complete the color change at the desired portion.
