| 20100182666 | SHEETING WITH COMPOSITE IMAGE THAT FLOATS - Techniques are described for forming microlens sheeting having composite images that appear to float with respect to the plane of the sheeting. As one example, a method comprises forming one or more images within a sheeting having a surface of microlenses, wherein at least one of the images is a partially complete image, and wherein each of the images is associated with a different one of the microlenses, wherein the microlenses have refractive surfaces that transmit light to positions within the sheeting to produce a plurality of composite images from the images formed within the sheeting so that each of the composite images appears to float with respect to the plane of the sheeting, and wherein forming the one or more images comprises forming the one or more images such that each of the composite images is associated with a different viewing angle range. | 07-22-2010 |
| 20110063392 | GENERATION OF COLOR IMAGES - Methods for generating a color image are provided which include a multi-layer construction in which at least one of the layers is a thermally activatable layer that includes a thermally activatable composition. The thermally activatable composition includes a non-linear light to heat converter composition and a color forming compound. Upon activation with a light source an image forms. | 03-17-2011 |
| 20110249332 | MULTILAYER OPTICAL FILMS HAVING SIDE-BY-SIDE MIRROR/POLARIZER ZONES - A reflective film includes interior layers that selectively reflect light by constructive or destructive interference, the layers extending from a first to a second zone of the film. In the first zone, the layers operate substantially as a reflective polarizer; in the second zone they operate substantially as a mirror. The layers may thus provide a first reflective characteristic in the first zone wherein normally incident light of one polarization state is substantially reflected and normally incident light of an orthogonal polarization state is substantially transmitted, and a second reflective characteristic in the second zone wherein normally incident light of any polarization state is substantially reflected. The film may have a first thickness in the first zone that is substantially the same as a second thickness in the second zone. Alternatively, the second thickness may be substantially less than the first thickness. Related methods, articles, and systems are also disclosed. | 10-13-2011 |
| 20110249334 | INTERNALLY PATTERNED MULTILAYER OPTICAL FILMS WITH MULTIPLE BIREFRINGENT LAYERS - A reflective film includes interior layers that selectively reflect light by constructive or destructive interference, the layers extending from a first to a second zone of the film. The interior layers include a first set of layers composed of a first material and a second set of layers composed of a different second material. The first and second sets of layers are both birefringent in the first zone, but at least some of the layers have reduced birefringence in the second zone. The reduced birefringence produces a second reflective characteristic in the second zone that differs from a first reflective characteristic in the first zone, this difference not being substantially attributable to any thickness difference between the first and second zones. The film may also incorporate absorbing agents to assist in the manufacture or processing of the film. Related methods and articles are also disclosed. | 10-13-2011 |
| 20110255163 | INTERNALLY PATTERNED MULTILAYER OPTICAL FILMS USING SPATIALLY SELECTIVE BIREFRINGENCE REDUCTION - A reflective film includes interior layers arranged to selectively reflect light by constructive or destructive interference, the layers extending from a first zone to a second zone of the film. The film has a first thickness and the interior layers provide a first reflective characteristic in the first zone; the film has a second thickness and the interior layers provide a second reflective characteristic in the second zone. The difference between the first and second reflective characteristics is not substantially attributable to any difference between the first and second thicknesses, which difference may be zero. Rather, the difference in the reflective characteristics is substantially attributable to reduced birefringence of at least some of the interior layers in one zone relative to the other zone. The film may also incorporate absorbing agents to assist in the manufacture or processing of the film. Related methods and articles are also disclosed. | 10-20-2011 |
| 20110255167 | MULTILAYER OPTICAL FILMS SUITABLE FOR BI-LEVEL INTERNAL PATTERNING - A reflective film includes a first optical stack that provides a first reflective characteristic and a second optical stack that provides a second reflective characteristic. The optical stacks also have first and second absorptive characteristics that are suitable to absorptively heat the respective stacks upon exposure to light including a write wavelength while maintaining the structural integrity of the stacks. The absorptive heating can change the first and second reflective characteristics to third and fourth reflective characteristics, respectively. A blocking layer that at least partially blocks light of the write wavelength may also be provided between the optical stacks to permit absorptive heating of any selected one of the optical stacks. The reflective characteristics of the optical stacks can thus be independently modified in any desired patterns by appropriate delivery of light beams that include the write wavelength. | 10-20-2011 |
| 20110269865 | THREE-DIMENSIONAL ARTICLES USING NONLINEAR THERMAL POLYMERIZATION - A method for building three-dimensional articles using a thermal polymerization process in provided. The articles are built by using a composition that includes a thermally polymerizable composition, a thermal initiator, and a nonlinear light-to-heat conversion material such as a reverse saturable dye. The article is built by the sequential exposure of adjacent voxels with a laser beam. Microlens arrays can be used to expose more than one voxel at a time. | 11-03-2011 |
