Appeal No. 96-1142 Application 07/939,180 case, the examiner has not carried this burden. For the above reasons, we conclude that the examiner has not carried his burden of establishing a prima facie case of obviousness over Chao of the process recited in any of appellants’ claims. Accordingly, the rejection of claims 7-11 over Chao is reversed. Rejection over Henning in view of Hombach Henning discloses mixtures of aqueous polymer dispersions which include (A) at least one aqueous dispersion having a film forming temperature below 70EC, with hydrophile groups, preferably a dispersion of polyurethanes having hydrophile groups, and (B) at least one aqueous dispersion of a polymer which does not form a film below 70EC and which has a melting point greater than 70EC, wherein the weight ratio of dispersions (A) to (B) is from 97:3 to 50:50, based on the solids content of the dispersions (pages 2, 3 and 10). The mixtures are disclosed as being useful for forming coatings, especially coatings on flexible substrates such as textile substrates or leather 9Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 NextLast modified: November 3, 2007
