| 20110155812 | HIGH CONDUCTIVE WATER-BASED SILVER INK - Disclosed is a conductive composition which can be used to form an aqueous conductive ink with increased conductivity. A film of the dry ink having a thickness of 5 microns or less has a surface roughness of less than 1.5 times the surface roughness of a cellulosic-based substrate which it coats. The aqueous conductive composition contains conductive particles, preferably silver, an anionic wetting agent and a styrene-acrylic copolymer. The composition is highly conductive and requires reduced drying energy. In addition, it may be applied to low cost substrates by high speed printing processes. | 06-30-2011 |
| 20100015412 | WATER BASED PRINTING INKS FOR NONWOVEN SUBSTRATES - Disclosed is a waterborne composition comprising of a water-based polyurethane, water, and colorant which can be used as a printing ink for non-woven articles. | 01-21-2010 |
| 20090326105 | HIGH TRANSPARENCY PIGMENTS - The present invention provides a method for preparing conditioned pigments that have smaller diameter and increased color strength, masstone and travel by milling pigment with a dispersant comprising polyurethane. Further, the invention provides the conditioned pigments prepared by the method of the invention and their applications to paints, coatings, inks, plastics, optical devices, color filters and so forth. | 12-31-2009 |
| 20090142526 | POLYMERIC DISPERSANTS - Dispersants for pigments as well as dispersions containing them, and compositions such as inks and coatings containing them are described. The dispersants are the reaction product of at least one dianhydride with at least two different reactants, each of which can be an amine, alcohol, or thiol, and at least one of which is polymeric. | 06-04-2009 |
| 20090142502 | DISPERSIONS OF NANO-SIZED MATERIALS - Nano-sized particles of inorganic material, e.g. zinc oxide, cerium oxide or titanium oxide, can be dispersed to form a stable dispersion in a liquid medium, by using as the dispersant a compound of formula (I): in which: R | 06-04-2009 |
| 20080295712 | Improved Coldset web Offset Printing - In a coldset web offset printing process, a substrate, e.g. newsprint, is printed with the desired matter and is then coated on both sides essentially simultaneously with a clear varnish to a film weight no more than 2 gsm dry weight on each side. | 12-04-2008 |
| 20080287686 | Process for Preparing Onium Salts - An 'onium salt, e.g. a quaternary ammonium salt, of an anionic dye maybe prepared by mixing an aqueous solution of a salt of the dye with a solution of a water-insoluble 'onium salt in an organic solvent, and separating a solution of the 'onium salt of the anionic dye in the organic solvent from the residual aqueous solution. | 11-20-2008 |
| 20080286486 | Carbonate Containing Energy-Curable Compositions - Polyfunctional cyclic carbonates provide a useful additional monomer for energy-initiated cationic copolymerisation with such other monomers and oligomers as epoxides and oxetanes. | 11-20-2008 |
| 20080255275 | Printing Inks for Nonwoven Substrates - A flexographic and/or rotogravure printing ink used on non-woven substrates contains polyurethane resin, solvent, and colorant. | 10-16-2008 |
| 20080248287 | Gas Barrier Coating Having High Thermal Resistance - A coating composition comprising a silylated polyvinyl alcohol and colloidal silica in an aqueous vehicle, where the solids content of the composition is not greater than 7.5% w/w, the silyl monomer content of the silylated polyvinyl alcohol is not greater than 3.0% (based on the monomers forming the silylated polyvinyl alcohol), the silylated polyvinyl alcohol comprises at least 50% w/w of the solids content of the composition, and the average particle size of the colloidal silica is from 5 to 80 nm, may be coated on a substrate with a layer of an inorganic compound to form a gas barrier lamella. | 10-09-2008 |
| 20080221234 | Acrylated Polyamide-Containing Printing Inks - The problem of misting in printing inks may be cured by using as the oligomer in an energy-curable printing ink a radiation-curable acrylate-modified aminoamide resin which is the Michael addition product of a polyol ester having at least two (meth)acrylate ester groups with an aminoamide thermoplastic polymer, the aminoamide thermoplastic polymer being the reaction product of a polyamine with an acid component which comprises a polymerised unsaturated fatty acid and a C2-C22 fatty acid, from 1 to 25% of the acid functionality forming the aminoamide polymer being said C2-C22 fatty acid, the resin being liquid at 25° C. | 09-11-2008 |
