Patent number: 7655296Abstract: The present invention is directed an oriented, foamed article having an ink-receptive surface, and a method of making the article. The invention provides a printable substrate comprising at least one high melt-strength, oriented polypropylene foam layer having an ink-receptive surface. The high melt-strength polypropylene having a melt strength of 25 to 60 cN at 190° C. The ink-receptive surface may comprise and oxidizing treatment, such as corona or flame-treatment of the foam surface, or may comprise an ink-receptive coating, such as a primer coating, on the foam surface. The oriented foam article is particularly useful in the preparation of printed security documents such as currency, stock and bond certificates, birth and death certificates, land titles and abstracts and the like.Type: GrantFiled: July 27, 2006Date of Patent: February 2, 2010Assignee: 3M Innovative Properties CompanyInventors: Christopher K. Haas, Robert D. Taylor, William B. Black, James M. Jonza, Terrence E. Cooprider

Patent number: 7094463Abstract: The present invention is directed to a process for producing a polypropylene foam by mixing a high melt strength polypropylene and a blowing agent to form a melt mixture, reducing the temperature of the melt mixture at the exit of the apparatus to an exit temperature that is no more than 30° C. above the melt temperature of the neat polypropylene while maintaining the melt mixture at a pressure sufficient to prevent foaming; passing the mixture through said exit shaping orifice and exposing the mixture to atmospheric pressure, whereby the blowing agent expands causing cell formation resulting in foam formation, and orienting said foam. The foam is useful as tape backings, thermal and acoustical insulation and as a diffuse reflector for use in optical applications such as computer displays.Type: GrantFiled: December 30, 2002Date of Patent: August 22, 2006Assignee: 3M Innovative Properties CompanyInventors: Christopher K. Haas, Mark D. Gehlsen, Sara B. Mortenson, Joan M. Strobel, Ravi K. Sura, David L. Vall

Patent number: 6890649Abstract: The present invention relates to aliphatic polyester microfibers, films having a microfibrillated surface, and methods of making the same. Microfibers of the invention can be prepared by imparting fluid energy, typically in the form of high-pressure water jets, to a highly oriented, highly crystalline, aliphatic polyester film to liberate microfibers therefrom. Microfibrillated films of the invention find use as tape backings, filters for particulate contaminants, such as face masks and water or air filters, fibrous mats, such as those used for removal of oil from water and those used as wipes, and thermal and acoustical insulation. Microfibers of the invention, when removed from the film matrix may be used in the preparation of woven or nonwoven articles and used as wipes for the removal of debris or dust from a surface. The microfibers and microfibrillated articles of the invention may be biodegradable, rendering them useful for geotextiles.Type: GrantFiled: August 25, 2003Date of Patent: May 10, 2005Assignee: 3M Innovative Properties CompanyInventors: Terry R. Hobbs, Philip P. Soo, Mario A. Perez, Christopher K. Haas, Robert S. Kody

Publication number: 20040258902Abstract: The invention is directed in part to an article that includes a polymer foam having a surface with surface microstructures, the surface microstructures have at least one extent or dimension of about 10 microns or more, preferably 50 microns or more. A maximum extent (unless it is a continuous rib-like structure) the microstructure is about 300 microns or less, preferably 200 microns or less, and generally a maximum height of 1000 microns or less, preferably 750 microns or less and a minimum height of 200 microns or more, preferably 300 microns or more. The foamed article may be provided in a variety of shapes, including a rod, a cylinder, a sheet, etc. In a preferred embodiment where the foam is provided in the form of a sheet, the foam has a pair of major surfaces, one or both of which can be provided with surface microstructures.Type: ApplicationFiled: June 18, 2003Publication date: December 23, 2004Applicant: 3M Innovative Properties CompanyInventors: Jayshree Seth, Christopher K. Haas, Ravi K. Sura, Katherine A.S. Graham, Janet A. Venne
