Synthetic resins or natural rubbers -- part of the class 520 series November recently filed with US Patent Office 11/09

20090292038 - Flame retardant photoimagable coverlay compositions and methods relating thereto: The present invention is directed to phosphorus containing (or “halogen free”) flame retardant photoimagable compositions useful as a coverlay material in a flexible electronic circuitry package. These compositions are generally photosensitive and comprise phosphorus containing acrylates and phosphorus-containing photo-initiators mixed with a polymer binder. The compositions of the present invention... Agent: Keading Konrad S E I Du Pont De Nemours And Company

20090292039 - Oxime ester compound and photopolymerization initiator containing the same: Disclosed is an oxime ester compound represented by the following general formula (I). (In the formula, R1, R2 and R3 independently represent R11, OR11, COR11, SR11, CONR12R13 or CN; R11, R12 and R13 Independently represent a hydrogen atom, an alkyl group having 1-20 carbon atoms, an aryl group having 6-30... Agent: Young & Thompson

20090292040 - Clear and colorless three-dimensional articles made via stereolithography and method of making said articles: The invention is a radiation curable liquid resin that can be used to make a clear and colorless, three-dimensional article by a stereolithography process. The clear and colorless three-dimensional articles have a clarity and transmittance of greater than about 67% as measured by UV-Visible spectrophotometer in the 400-500 nm range;...

20090286899 - Platinum catalysts supported on nanosize titanium dioxide, their use in hydrosilylation and compositions comprising such catalysts: Nanosize titanium dioxide having supported thereon metallic platinum are efficient hydrosilylation catalysts whose hydrosilylation activity may be increased by irradiation. The catalysts are prepared by depositing soluble platinum compounds on a titanium dioxide sol or titanium dioxide pigments followed by drying, calcining, and reduction to platinum metal. The catalysts are... Agent: Brooks Kushman P.C.

20090286900 - Modified natural rubber, method for producing modified natural rubber, rubber composition, and tire: The present invention provides a modified natural rubber obtained by adding a compound to at least one natural rubber raw material selected from the group consisting of a solid natural rubber, a natural rubber latex, and a natural rubber derivative and then irradiating the mixture of the natural rubber raw... Agent: Birch Stewart Kolasch & Birch

20090275673 - Benzocyclobutene based polymer formulations and methods for processing such formulations in oxidative environments: The use of hindered phenol containing anti-oxidants enable arylcyclobutene-based formulations to be cured in oxygen containing environments such as air without unacceptable degradation in key properties of dielectric constant, water uptake, or transmittance.... Agent: The Dow Chemical Company

20090275674 - Uv/eb curable biobased coating for flooring application: A radiation curable biobased coating, such as a UV/EB curable biobased coating, for flooring applications includes a biobased component comprising renewable and/or biobased materials. The biobased component is selected from the group consisting of a biobased resin, a biobased polyol acrylate, or a biobased polyol. The biobased component is blended...
