摘要:
A metallic toner fluid composition that contains (A) electrostatically charged, colloidal elemental metal particles dispersed in an electrically nonconductive organic carrier liquid having a dielectric constant less than about 3.5 and a volume resistivity greater than about 10.sup.12 ohm-cm, (B) a soluble surfactant in an amount sufficient to charge and stabilize the colloidal metal dispersion, and (C) an effective amount of organosol particles and/or a soluble polymer that is not a soluble surfactant (B). Also disclosed is a substrate coated with elemental metallic toner fluid particles. The coated substrate can act as a donor substrate for thermal mass transfer of images to a secondary receiving substrate by performing either or both of the following steps, in any order:(a) transferring the elemental metal coating from the primary substrate to the secondary receiving substrate;(b) contacting the elemental metal coated primary or secondary substrate with an electroless metal plating solution.

The present disclosure provides methods for forming asymmetric membranes. More specifically, methods are provided for applying a polymerizable species to a porous substrate for forming a coated porous substrate. The coated porous substrate is exposed to an ultraviolet radiation source having a peak emission wavelength less than 340 nm to polymerize the polymerizable species forming a polymerized material retained within the porous substrate so that the concentration of polymerized material is greater at the first major surface than at the second major surface.

摘要:
A transparent anti-reflective structured film (10) comprising a structured film substrate (12) having a structured face (14), with anti-reflective structures, for example, in the form of prismatic riblets (16) defining a structured surface. The structured face is anti-reflective to light, with at least a substantial portion of the structured surface comprising a glass-like surface. At least the anti-reflective structures comprise a cross-linked silicone elastomeric material and the glass-like surface comprises an Si02 stoichiometry. A solar light energy absorbing device is disclosed, comprising the transparent anti-reflective structured film disposed so as to be between a source of light energy and a light energy receiving face of a light absorber, when light energy is being absorbed by the light absorber.

摘要:
In one aspect the invention provides an energy efficient polymerization method comprising irradiating a polymerizable composition and a photoinitiator with a source of essentially monochromatic radiation where the photoinitiator and the wavelength of the radiation source are selected such that the extinction coefficient of the photoinitiator at the peak wavelength of the source is greater than about 1000 M−1 cm−1 and such that the photoinitiator absorbs at least two percent of the actinic radiation incident on the coating. In another aspect the invention provides energy efficient methods of polymerizing polymerizable compositions and crosslinking crosslinkable compositions by irradiating the respective compositions with a low power source of essentially monochromatic radiation. The low power energy sources have an input power of less than about 10 W/cm. Articles made from the above methods, including polymer films having release coatings, adhesive coatings, hard coatings and the like thereon, also are provided.
