    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 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： 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.

    摘要： The ink of the invention comprises a vehicle and a colorant. The colorant is a pigment that has been treated to reduce nozzle outs in the inkjet printers. The performance of these pigments is improved by forcing the pigment through an acute pressure valve process wherein the pigment is homogenized to a size of about 0.1 .mu.m.

    摘要： Systems and method for optically recording data. One system comprises a disc comprising a substrate and a markable coating on said substrate, the markable coating having a thickness less than 1 μm and comprising: a matrix; and a color-forming agent included in the matrix and comprising a leuco dye and developer; wherein the leuco dye is selected to change from high reflectance of radiation with wavelengths between 400 and 500 nm to low reflectance of radiation with wavelengths between 400 and 500 nm when activated by the application of energy above a threshold level; and a marking light source positioned so as to illuminate the disc in a desired manner.
