    Abstract: A laser-marking medium comprises at least a base layer and a masking layer formed on one side of a support element in the stated order. The base layer has laser light absorptivity, and the masking layer contains metal powder and a white pigment. A laser beam applied to the laser-marking medium is absorbed by the base layer having laser light absorptivity, and the base layer heats and breaks, whereby the masking layer in the laser applied region is removed, and a lightness difference is generated between a laser beam non-applied region of the masking layer and the laser beam applied region with the masking layer removed so as to make marks in the laser beam applied region distinctly visible.

The particles are composed of silicon or germanium and are optionally produced at sizes such that the particles exhibit quantum size effects. The particles are produced from an organometallic (tetra-organosilicon or tetra-organogermanium) precursors which is dissolved in a solvent that transmits a wavelength of light that photolyzes the precursor. The reaction is carried out under an inert atmosphere. A passivating agent is added to arrest particle growth and impart solubility to the particle. Optionally, a dopant is incorporated into the particle in the course of production so as to modify the electronic properties of the semiconductor particle.

  • Patent number: 5843329
    Abstract: Magnetic paint or ink additives are formulated from ferromagnetic particles, preferably iron powder, having a mixed particle range of from about 0.01.mu. to about 297.mu., and preferably to about 250M and more, preferably from about 0.01.mu. to about 37 to 44.mu.; 6 to 20.mu. particles are used in one latex-based embodiment. Preferred additives are formulated by blending the particles with a surfactant, a surfactant mixture, or a surfactant and alcohol mixture in amounts sufficient to suspend the particles; a polyvinyl acetate polyer is used in one embodiment. The additives may be blended with any oil-, latex-, or lacquer-based paint, ink, or coating to form a magnetic paint or coating having a viscosity substantially similar to the paint or ink containing no particles and/or additive. Surfaces such as paper, cloth, wood, wallboard, sheet rock, foam, foam board, plywood, plastic, fiberboard, and the like so coated may be cut with conventional woodworking tools, scissors or knives.

  • Patent number: 5840418
    Abstract: A clad member is made up of a plate-like clad base material having on its surface a recessed portion, and solidified portions of a metallic material which is different in kind from the clad base material. The solidified portions are disposed in the recessed portion at a distance from each other and are bonded with the clad base material through melting. The clad member is manufactured by forming an elongated recessed portion on a surface of a plate-like clad base material. The recessed portion is filled with a comminuted metallic material which is different in kind from the clad base material. A laser beam is irradiated onto a plurality of regions which are separated from each other in a longitudinal direction of the recessed portion such that partly melted portions of the comminuted metallic material are generated to thereby bond the comminuted metallic material with the clad base material. The melted portions are solidified. The remaining non-molten portions of the comminuted metallic material are removed.

  • Patent number: 5837354
    Abstract: A flexible metallized product having a base material made of a soft resin material comprising polypropylene mixed with diene or polypropylene mixed with rubber, a base coat layer formed on the surface of the base material, a metal thin film layer formed on the surface of the base coat layer and a top coat layer covering the metal thin film layer. The metal thin film layer is made of a corrosion resistant metal such as chromium. The metal thin film layer has a thickness of at least 150 .ANG. and no greater than 800 .ANG. by means of a vacuum vapor deposition or sputtering. The metal thin film layer is constituted by a plurality of metal particles. The metal particles are disposed such that adjacent metal particles are in contact with one another to form a grain boundary therebetween.

  • Patent number: 5707697
    Abstract: An automotive quality paint coat is laminated to the exterior surface of a molded plastic car body member or panel. In one embodiment, the paint coat includes an exterior clear coat above a color coat. During processing, the clear coat and color coat are each coated on a temporary flexible casting sheet and dried. A high gloss surface is transferred to the clear coat from the casting sheet. The paint coat is then transferred from the casting sheet to a thin, semi-flexible thermoformable plastic backing sheet by dry paint transfer-laminating techniques. The resulting laminate is thermoformed into a complex three-dimensional shape of the car body member or panel. The preformed laminate is then bonded to an underlying plastic substrate material, by injection-cladding techniques, for example, to form the finished article. The paint coat has sufficient elongation to retain exterior automotive appearance and durability properties during thermoforming without deglossing.
