Publication number: 20030135004Abstract: A composition, comprising, in an appropriate medium, at least one polymer with a highly specific ordered structure is disclosed. These compositions find a specific application in the field of make-up and are capable of being applied to keratinous fibres, in particular to the nails, eyelashes, eyebrows and hair. In particular, these compositions can make it possible to obtain a film which exhibits good resistance to chipping, to impacts, to rubbing movements, to scratches and/or to pressing actions.Type: ApplicationFiled: January 17, 2003Publication date: July 17, 2003Applicant: L'OrealInventor: Nathalie Mougin

Patent number: 6586533Abstract: Articles are formed from a thermosetting composition based on polybutadiene or polyisoprene resins which are subjected to a high temperature cure step of greater than 250° C. The thermosetting compositions may include fillers such as particulate ceramic fillers and may also include woven webs for improved dimensional stability and decreased brittleness. The formation process of this invention is particularly well suited for making electrical circuit substrates for microwave and digital circuits, typically in the form of the thermosetting composition being laminated on one or both opposed surfaces to metal conductive foil (e.g., copper).Type: GrantFiled: May 4, 1994Date of Patent: July 1, 2003Assignee: World Properties, Inc.Inventors: Vincent R. Landi, J. Mark Mersereau, Walter A. Robbins, Michael E. St. Lawrence

Patent number: 6582791Abstract: A vinyl graphic marking film or label coated with a pressure sensitive acrylic adhesive designed to achieve high or permanent adhesion to polymeric low energy surfaces is disclosed. In addition to good adhesion to low energy surfaces, the graphic marking film or label may have microperforated or micro-rough edges which initiate tearing when removal is attempted. The article maintains flexibility and film strength for easy fabrication in graphic marking film or label manufacture.Type: GrantFiled: January 23, 2001Date of Patent: June 24, 2003Assignee: 3M Innovative Properties CompanyInventors: Richard L. Peloquin, Albert I. Everaerts, Kenneth D. Wilson, Stephen J. Galick
