Crosslinking agent (b) has a Tg of from 40 to 70° C./105 to 158° F. and is a solid at 23.9° C./75° F. when at 100% by weight solids. Crosslinking agent (b) is melt mixed into acrylic polymer (a) to provide a first dispersion and said first dispersion is emulsified in water to provide an aqueous dispersion. In a preferred embodiment, the aqueous electrodepositable primers comprise at least 50% by weight water and an acrylic polymer (a) having one or more salted sites per molecule.Type: GrantFiled: November 16, 2001Date of Patent: January 1, 2008Assignee: BASF CorporationInventors: Charles L. Tazzia, Robert D. Schiller, William H. Alford, Grant E. Cooley

Patent number: 7294670Abstract: An aqueous urethane resin dispersion for bonding can be used in wet lamination and dry lamination and can be reactivated easily at a low temperature of about 50 to 70° C. after drying, and is also superior in coatability, adhesive strength, and heat resistance. The aqueous dispersion of a polyurethane resin is superior in contact adhesiveness immediately after lamination and also has good permeability and good coatability not only on bases having smooth surfaces such as plastics and metals, but also on porous bases such as fibers, papers, and buffed leathers; an aqueous adhesive using the aqueous dispersion; and an article to which it is applied. The aqueous polyurethane resin dispersion has at least one of a sulfonate group and a carboxylate group, wherein an average particle diameter of the polyurethane resin is 0.05 to 0.30 ?m and a surface tension of the aqueous dispersion (A) is 40 mN/m or less.Type: GrantFiled: September 20, 2002Date of Patent: November 13, 2007Assignee: Dainippon Ink and Chemicals, Inc.Inventors: Kazuo Kuba, Mitsuru Kitada
