Patent number: 5976402Abstract: Compositions containing p-dinitrosobenzene deposited onto a support of a chemically inert material which is solid at room temperature are provided. The composition is preferably formed by depositing p-dinitrosobenzene from a solution or by sublimation or in the course of its synthesis in the presence of one or more supports. Hydrophilic or hydrophobic silica, hydrophobicized zeolites, carbon blacks and layer silicates are examples of supports. The composition is useful in the production of adhesives, more particularly for bonding elastomers, e.g. in the polymerization or crosslinking of elastomers, and even more particularly in the bonding of rubber to metal.Type: GrantFiled: October 3, 1995Date of Patent: November 2, 1999Assignee: Henkel Kommanditgesellschaft auf Aktien (KGaA)Inventors: Burkhard Muller, Brigitte Calaminus, Wolf-Dieter Beiersdorf, Werner Gruber, Hans-Josef Hoffmann, Rainer Wefringhaus, Peter Kuhm, Norbert Hubner, Christian Block

Patent number: 5877253Abstract: A method of preparing an inorganic pigment dispersion useful in the preparation of latex paints is provided. The method comprises dispersing an inorganic pigment in an aqueous medium further comprised of a dispersing polymer, said aqueous medium being essentially free of volatile organic solvents. The dispersing polymer is derived from monomers consisting essentially of an ethylenically unsaturated aromatic monomer having an unsubstituted ethylenic group, an ethylenically unsaturated aromatic monomer having an alkyl-substituted ethylenic group, and an ethylenically unsaturated acid monomer. The amount of the ethylenically unsaturated acid monomer is sufficient to permit the dispersing polymer to associate with an inorganic pigment in an aqueous medium in a manner which disperses the inorganic pigment in the aqueous medium to form a stable aqueous dispersion of said inorganic pigment.Type: GrantFiled: June 26, 1996Date of Patent: March 2, 1999Assignee: Henkel CorporationInventors: Bruce L. Matta, Samuel A. Firman, George A. Smith, Reuben H. Grinstein

Patent number: 5623041Abstract: Provided are polymers having the formula: ##STR1## wherein R.sup.1 is an aromatic group having from 6 to 10 carbon atoms, R.sup.3 is a fatty alkyl group having from 12 to 22 carbon atoms, and R.sup.5 is a hardening alkyl group having from 1 to 4 carbon atoms, R.sup.2, R.sup.4, and R.sup.6 are each independently hydrogen or methyl, and y, is chosen in relation to x and z such that a film of said polymer has improved alkali resistance. Also provided is a method of coating a substrate comprising (i) contacting a surface of a substrate with an aqueous dispersion composition comprising a polymer as defined above, and (ii) drying said surface to form a film of said polymer in contact with said surface. In preferred methods, said polymer in aqueous dispersion is supplied to said surface by a hydrophilic cylindrical transfer roll. These polymers are particularly useful as the binder for an ink composition, or an overprint varnish, having good alkali resistance.Type: GrantFiled: March 17, 1995Date of Patent: April 22, 1997Assignee: Henkel CorporationInventor: Steven P. Boucher

Patent number: 5565567Abstract: Polymerizable compounds based on N-acylamido-piperazines are provided. Such compounds have the formula: ##STR1## wherein: R.sup.1, R.sup.2, and R.sup.3 are each independently selected from the group consisting of hydrogen and lower alkyl,B is a linking group selected from the group consisting of carbonyl, sulfonyl, amide, and carboxyl;n is ore or zero;R.sup.4 is a radical selected from the group consisting of a higher aliphatic group (i.e. at least four carbon atoms, preferably from about 6 to about 50 carbon atoms), a substituted higher aliphatic group, an alicyclic group, a heterocyclic group, a non-benzenoid aromatic group, and a substituted aromatic group. These compounds can be incorporated into a polymerizable composition. The compound is preferably present in said composition in a major amount on a mole percent basis of the polymerizable monomers. These polymerizable compositions are useful as coatings, particularly in formulations containing a photoinitiator susceptible to ultra-violet radiation.Type: GrantFiled: May 19, 1994Date of Patent: October 15, 1996Assignee: Henkel Corporation.Inventor: Paul E. Share

Patent number: 5563214Abstract: Aqueous compositions comprised of a major amount of water and a minor amount of a polymerizable compound based on N-acryloyl-piperazine are provided. Such compounds have the formula: ##STR1## wherein: R.sup.1, R.sup.2, and R.sup.3 are each independently selected from the group consisting of hydrogen and lower alkyl,B is a linking group selected from the group consisting of carbonyl, sulfonyl, amide, and carboxyl;n is one or zero;R.sup.4 is a radical selected from the group consisting of a higher aliphatic group (i.e. at least four carbon atoms, preferably from about 6 to about 50 carbon atoms), a substituted higher aliphatic group, an alicyclic group, a heterocyclic group, a non-benzenoid aromatic group, and a substituted aromatic group. These compounds can be used as an emulsifier in emulsion polymerization.Type: GrantFiled: August 9, 1994Date of Patent: October 8, 1996Assignee: Henkel CorporationInventors: Paul E. Share, Wallace H. Pippin

Patent number: 5464494Abstract: Film-forming reactive systems for the surface-to-surface bonding and/or coating of substrates, more particularly for heat-sealable coatings are provided. The system is based on an aqueous dispersion of at least two epoxy-curable resins (I) and an epoxy compound as the curing component (II). The epoxy-curable resins are a polyurethane polymer containing epoxy-reactive functional groups present as the curable resin (Ia) and an aqueous dispersion of an acrylate and/or methacrylate homopolymer or copolymer containing carboxyl and/or methylol groups present as an additional curable resin (Ib). Also provided is a method for the production of laminates which employs the reactive system to bond substrates.Type: GrantFiled: May 10, 1994Date of Patent: November 7, 1995Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Gerd Bolte, Guenter Henke, Ulrike Brueninghaus
