摘要:
A method of forming a metallic material on a receptor that includes the steps of: placing a donor element proximate a receptor, wherein the donor element includes a donor substrate and a thermal transfer layer, wherein the thermal transfer layer includes a catalytic material, and wherein the thermal transfer layer of the donor element is placed proximate the surface of the receptor; thermally transferring at least a portion of the thermal transfer layer from the donor element to the receptor; and electrolessly depositing a metallic material on the receptor by growth of the metallic material on the catalytic material.

摘要:
Radiation curable thermal transfer elements including a substrate and a light-to-heat conversion layer overlaying the substrate, and processes to make the thermal transfer elements. The light-to-heat conversion layer is derived from a radiation curable material capable of being cured by exposure to radiation at a curing wavelength and an imaging radiation absorber material not substantially increasing radiation absorbance at the curing wavelength. The radiation curable transfer elements can be used in processes for making organic microelectronic devices.

Polymeric fibers and methods of making the polymeric fibers are described. The polymeric fibers are crosslinked hydrogels or dried hydrogels that are prepared from a precursor composition that contains polymerizable material having an average number of ethylenically unsaturated groups per monomer molecule greater than 1.0. The polymeric fibers can contain an optional active agent.
摘要:
A method for forming a color shifting film on a support, the film comprising a reflective stack disposed adjacent to the support and an image is disclosed. The reflective stack comprises an at least partially transparent spacer layer comprising a substituted acrylamide polymer disposed between a partially reflective first layer and a reflective second layer. The acrylamide layer has a thickness sufficient to produce an interference color.

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.
摘要:
A method of preparing an adhesive composition that includes exposing a free-radically polymerizable pre-adhesive composition to a monochromatic radiation source having a peak intensity at a wavelength falling within the range of about 250 nanometers to about 600 nanometers to polymerize the pre-adhesive composition and form the adhesive composition.
摘要:
A method of making a colloidal metal dispersion that is useful as a toner fluid. The method involves reducing a palladium and/or platinum metal of a metallo-organic palladium and/or platinum metal salt in a dispersing medium that contains a soluble surfactant and a carrier liquid. The palladium and/or platinum metal of the metallo-organic metal salt is reduced in the dispersing medium to form elemental metal particles. The soluble surfactant is present in the dispersing medium in an amount sufficient to charge and stabilize the elemental metal particles as a colloidal metal dispersion.
