    Abstract: A composition of matter useful as a hotmelt adhesive is provided. The composition is comprised of a polyamide based on dimerized fatty acid and having an amine value higher by at least two units than the acid value of said polyamide and a filler comprised of a carbonate. The filler is preferably comprised of fine particles of calcium carbonate. The adhesive is particularly useful for bonding metals, e.g. to plastics and the bonding of cables with multilayer sheaths, e.g. in optical cables and power cables.

    Abstract: An aqueous dispersion containing a polyamide and non-polyamide polymer is prepared by dissolving the polyamide in an organic solvent with a surfactant to form a polyamide solution. Water is then added to the polyamide solution to form an aqueous dispersion. The non-polyamide polymer can be added before or after the addition of water. The polyamide/non-polyamide dispersion can be used to produce an ink with better adhesion to plastic substrates and reduced blocking problems.
