Patent number: 6576717Abstract: Disclosed is a water-dispersible acrylic-modified polyester resin containing sulfonate groups prepared by addition copolymerization of ethylenically unsaturated vinyl monomers and a polyester. The polyester is prepared from a polycondensation reaction with dicarboxylic acids, glycols, ethylenically unsaturated monomer, and a minor amount of a sulfomonomer. The acrylic-modified polyester is prepared by first producing the polyester under polycondensation conditions followed by the addition polymerization of the ethylenically unsaturated vinyl monomers. The acrylic-modified polyesters can be formed into a coating composition that has zero or very little organic solvent and is very useful to produce crosslinked cured enamels having excellent gloss, hardness, impact resistance, and water resistance such as those used in automotive finishes, appliance, and coil coatings.Type: GrantFiled: April 24, 1995Date of Patent: June 10, 2003Assignee: Eastman Chemical CompanyInventor: Thauming Kuo

Patent number: 6385882Abstract: A two-dimensional display having a three-dimensional visual appearance has printed on a substantially flat or planar surface a predetermined message or information. Superposed over the message is a lenticular lens. Adjacent to the message are a series of spaced apart lines which may either be coplanar or non-coplanar relative to the message. The spaced apart lines are arranged so that they are in a non-registration relationship with the spacing of individual lenticules forming the lenticular lens. The display produces an appearance of having the lines float or move as a viewer's focal angle or perspective of the display changes. A method for making such a display is also provided.Type: GrantFiled: November 20, 2000Date of Patent: May 14, 2002Assignee: Eastman Chemical CompanyInventors: Kenneth Conley, Candace Michele Tanner
