Patent number: 5601878Abstract: The invention relates to a process for the production of two-coat finishes, in which a pigmented basecoat is first applied, the resulting basecoat film is coated with a powder clearcoat, and basecoat and clearcoat are subsequently baked together. In accordance with the invention, the powder clearcoat employed is a powder coating which contains an epoxide group-containing polyacrylate resin as binder and a mixture of (A) a polyanhydride and (B) a carboxyl group-containing polyester resin as crosslinking agent. The polyester resin can be prepared by reacting a diol (b1), a compound (b2) which contains per molecule at least three functional groups selected from hydroxyl, primary amino, secondary amino, carboxyl and acid anhydride groups, and (b3) a dicarboxylic acid in a molar ratio of (b1): (b2): (b3)=0.0 to 3.0: 1.0: 1.5 to 9.0 to give a polyester resin having an acid value of 40 to 300.Type: GrantFiled: January 26, 1995Date of Patent: February 11, 1997Assignee: BASF Lacke + Farben.

Patent number: 5532053Abstract: The present invention relates to a laminate film useful as a material from which to manufacture surgical and other protective garments. The laminate film comprises at least one layer formed from a first polyetherester copolymer produced from the condensation reaction of dimethyl-1,4-cyclo hexane dicarboxylate and 1,4-cyclo hexane dimethanol and poly(tetramethylene ether glycol) and a second layer comprising a material selected from the group consisting of an ethylene-vinyl acetate copolymer, an ethylene methacrylate copolymer, a second polyetherester copolymer, an anhydride modified polyolefin copolymer, and a polyether block amide copolymer. The total amount of the first polyetherester copolymer present in the laminate is greater than or equal to 35 wt. % of the total weight of the laminate film to provide strength to the laminate film. The laminate film may be bonded to one or more layers of polyesters, polyolefins, polyamides, and non-woven fabrics.Type: GrantFiled: March 1, 1994Date of Patent: July 2, 1996Assignee: W. R. Grace & Co.-Conn.Inventor: Walter B. Mueller
