The invention discloses processes for thermal transfer patterning of a nanoparticle layer and a corresponding proximate portion of a carrier layer, and optionally additional transfer layers, together onto a thermal imaging receiver. The invention is useful for dry fabrication of electronic devices. Additional embodiments of the invention include multilayer thermal imaging donors comprising in layered sequence: a base film, a carrier layer and a nanoparticle layer. The carrier layer can be a dielectric or conducting layer. When the carrier layer is a dielectric layer, the base film includes a light attenuating agent in the form of a dye or pigment.
摘要:
Methods of forming a pattern of filled dielectric material on a substrate by thermal transfer processes are disclosed comprising exposing to heat a thermally imageable donor element comprising a substrate and a transfer layer of dielectric material. The exposure pattern is the image of the desired pattern to be formed on the substrate, such that portions of the layer of dielectric material are transferred onto the substrate where the electronic device is being formed. The filled dielectric material can be patterned onto a gate electrode of a thin film transistor. The pattern dielectric material may also form an insulating layer for interconnects. Donor elements for use in the process are also disclosed. Methods for forming thin film transistors and donor elements for use in the thermal transfer processes are also disclosed.

摘要:
A polymeric dispersant for pigments based on an acrylic graft copolymer wherein the graft copolymer has a weight average molecular weight of about 5,000-100,000 and comprises a hydrophobic polymeric backbone and discrete anionic and nonionic hydrophilic side chains attached to the backbone. These graft copolymers are useful as dispersants in aqueous systems, and are particularly useful in formulating exterior water borne coatings for automobiles and trucks.

摘要:
A pigment dispersion useful for forming coating compositions containing dispersed pigment, a carrier solvent and an aminated macromonomer dispersant (binder) is disclosed. The aminated macromonomer dispersant is preferably prepared by the reaction of terminally unsaturated macromonomers synthesized by cobalt-catalyzed chain transfer free radical polymerizations of methacrylic monomers with monomeric or oligomeric amines.
摘要:
Dispersions containing a liquid vehicle (which can be aqueous, semi-aqueous or non-aqueous), organic or inorganic particles (or mixtures) that are insoluble in the liquid vehicle and a polymeric dispersant, preferably a structured polymeric dispersant, having one or more segments soluble in the liquid vehicle and one or more segments insoluble in the liquid vehicle, have improved stability when the insoluble segment(s) contains cross-linking groups which are cross-linked to itself or a cross-linking compound such as a polyfunctional monomer, oligomer or polymer to form an encapsulation network that entraps the particles which are particularly useful for paints or inks in coating and printing applications.
