Patent number: 6635704Abstract: An organic particulate-filled adhesive is provided comprising ionomeric particulate dispersed in a polymer matrix containing water-soluble polymer or water-dispersible polymer. The adhesive preferably contains a plasticizer. If desired, in some formulations, the adhesive can contain additives, such as opacifying agents, skin cleansers, skin moisturizers, vitamins, and herbal extracts. The adhesive can have pressure sensitive adhesive properties, although such properties are not necessary. The adhesive can be formulated so as to be useful as a repulpable adhesive and as a cosmetic adhesive.Type: GrantFiled: November 29, 2001Date of Patent: October 21, 2003Assignee: 3M Innovative Properties CompanyInventors: Michael R. Engel, Chung I. Young, Michael Govek, Michael D. Delmore, Michael R. Stumpf, Chi-Ming Tseng, Michael L. Ruegsegger

Patent number: 6589650Abstract: A cover slip material and a method of making and using the same are provided. The material comprises (a) a light transmissible polymeric backing having first and second surfaces; (b) a tack free bonding layer disposed on the first surface of the backing, the bonding layer comprising polymers selected from the group consisting of acrylate, methacrylate, and combinations thereof; and (c) a protective coating disposed on the second surface of the backing. Upon exposure to an environmentally friendly activating solvent such as terpene, d-limonene, esters of coconut oil and aliphatic hydrocarbon blends, the bonding layer acquires tacky properties causing the cover slip to adhere to a specimen previously mounted on a microscope slide.Type: GrantFiled: August 7, 2000Date of Patent: July 8, 2003Assignee: 3M Innovative Properties CompanyInventors: Michael Govek, Babu N. Gaddam, Cynthia M. Hogerton, Audrey S. Huang, Maureen A. Kavanagh, Junkang Liu, Michael L. Ruegsegger

Patent number: 6107366Abstract: The present invention provides thermoplastic ophthalmic lens blocking compositions that have many advantages over traditional metal alloy materials. Preferred compositions comprise a blend of a homopolymer or copolymer of epsilon-caprolactone with a modifier selected from the group consisting of carboxylic; straight chain monohydric alcohols; branched chain monohydric alcohols; polyethylene glycols; and polyethylene glycol ethers. The composition may also comprise one or more fillers or heat absorbing materials. In one embodiment, the composition is used to fill the cavity between a preformed lens block and a lens. In another embodiment the composition is used to form a lens block. Methods of holding a lens blank are taught. Tapes that provide a receptive surface against which the composition may be adhered are disclosed.Type: GrantFiled: April 7, 1998Date of Patent: August 22, 2000Assignee: 3M Innovative Properties CompanyInventors: Sharon R. Benjamin, Michael Govek, John H. Ko, Joel D. Oxman, Carole Sedlock, F. Andrew Ubel, Todd R. Williams

Patent number: 6036313Abstract: The present invention provides thermoplastic ophthalmic lens blocking compositions that have many advantages over traditional metal alloy materials. Preferred compositions comprise a homopolymer or copolymer of epsilon-caprolactone, have a number average molecular weight between 3,000 and 100,000, and a polydispersity less than 10. The composition may also comprise one or more modifiers, fillers or heat absorbing materials. In one embodiment, the composition is used to fill the cavity between a preformed lens block and a lens. In another embodiment the composition is used to form a lens block. Methods of holding a lens blank are taught. Tapes that provide a receptive surface against which the composition may be adhered are disclosed.Type: GrantFiled: May 6, 1998Date of Patent: March 14, 2000Assignee: 3M Innovative Properties CompanyInventors: Sharon R.

Patent number: 5885700Abstract: The present invention provides thermoplastic ophthalmic lens blocking compositions that have many advantages over traditional metal alloy materials. Preferred compositions comprise a blend of (i) a hydrocarbon resin, preferably an aromatic hydrocarbon resin; (ii) a side chain crystallizable hydrocarbon polymer or copolymer; and (iii) optionally an modifier or mixture of modifiers, preferably straight chain alcohols. The composition may also comprise one or more modifiers, fillers or heat absorbing materials. In one embodiment, the composition is used to fill the cavity between a preformed lens block and a lens. In another embodiment the composition is used to form a lens block. Methods of holding a lens blank are taught. Tapes that provide a receptive surface against which the composition may be adhered are disclosed.Type: GrantFiled: March 17, 1997Date of Patent: March 23, 1999Assignee: Minnesota Mining and Manufacturing CompanyInventors: James A.

Patent number: 5827390Abstract: The present invention provides methods of holding ophthalmic lens blanks using thermoplastic lens blocking compositions. Preferred compositions either comprise a homopolymer or copolymer of epsilon-caprolactone, have a number average molecular weight between 3,000 and 100,000, or have a polydispersity less than 10. The composition may also comprise one or more modifiers, fillers or heat absorbing materials. In one method, the composition is injected into the cavity between a preformed lens block and a lens. In another method, the surface of a lens block comprising the thermoplastic lens blocking composition is heated and formed against the lens blank. Tapes that provide a receptive surface against which the composition may be adhered are disclosed.Type: GrantFiled: September 13, 1996Date of Patent: October 27, 1998Assignee: Minnesota Mining and Manufacturing CompanyInventors: Sharon R. Benjamin, Michael Govek, Patrick D. Hyde, John H. Ko, Philip G. Martin, Joel D. Oxman, William L. Parish, Jr., Carole Sedlock, Richard L. Severance, F. Andrew Ubel, Todd R. Williams
