Abstract: 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.

Abstract: Transparent iron oxide pigment dispersions which produce waterborne coating compositions having excellent transparency and reduced haze are provided. The dispersions contain dispersed pigment, an aqueous carrier, and a mixture of water-dispersible acrylic copolymer dispersants, the mixture containing at least one acrylic copolymer dispersant having acid functional groups, at least one acrylic copolymer dispersant having phosphate functional groups, and optionally at least one acrylic copolymer dispersant having alkyl amino groups and preferably benzyl groups in the pigment anachoring segment. Such pigment dispersions are useful in forming automotive waterborne paints, particularly “metallic” automotive paints.

Abstract: This invention provides for an aqueous metallic flake containing coating composition having improved glamour. The coating composition includes a neutralized phosphated segmented copolymer dispersed in an aqueous carrier. The phosphorous moiety in the segmented copolymer passivates the metallic flakes, such as aluminum flakes, used to produce the glamour. As a result, generation of hydrogen gas is substantially reduced. The segmented copolymer is provided with hydrophobic and nonionic hydrophilic segments. Applicants have discovered that by including a nonionic hydrophilic segment in the segmented copolymer, glamour of the resultant coating composition can be improved.

Abstract: 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.
