| 20080207811 | PIGMENT BASED INKS FOR HIGH SPEED DURABLE INKJET PRINTING - An ink composition comprising (a) water, (b) pigment particles dispersed with a dispersant or self dispersing without the need for a dispersant, (c) at least one humectant, and (d) at least one polyurethane additive which is distinct from the dispersant, having an average molecular weight of at least about 10,000 and a sufficient number of acid groups to provide an acid number greater than about 60, the polyurethane being present at a level of at least 10 percent by weight relative to the pigment particles and comprising a polyether segment having a molecular weight greater than 250 and less than 2900, wherein the acid groups on the polyurethane are at least partially neutralized only with a monovalent inorganic base. | 08-28-2008 |
| 20080207820 | PIGMENT BASED INKS FOR HIGH SPEED DURABLE INKJET PRINTING - An ink composition comprising (a) water, (b) pigment particles, (c) at least one humectant, (d) at least one polyurethane having an average molecular weight of at least about 10,000 and a sufficient number of acid groups to provide an acid number from 60 to about 130, and being present at a weight concentration of greater than 0.7%, and (e) at least one water soluble acrylic polyiner comprising carboxylic acid groups, present at a weight concentration of greater than 0.6%, wherein the acid groups on the polyurethane and acrylic polymers are at least partially neutralized only with a monovalent inorganic base. | 08-28-2008 |
| 20080278663 | ANAMORPHIC MICROLENS ARRAY - An LC display comprises in order (a) a light source, (b) a transparent polymeric film bearing on the light exit surface of the film an array of close-packed convex microlenses having a distribution of sizes and oriented in one direction, whereby the light output is preferentially spread in a desired direction, and (c) an LC panel. A related process and film are also disclosed. | 11-13-2008 |
| 20080310186 | LIGHT EMITTING DEVICE WITH MICROLENS ARRAY - A method of manufacturing a micro-lens array and light-emitting device, comprising forming a first structured polymer film with close packed surface cavities having a mean diameter of less than 20 micrometers and a relatively lower surface energy surface, forming a transparent second structured film with an array of microlenses formed thereon corresponding to the cavities of the first structured film, wherein the second structured film comprises a relatively high surface energy material and has a refractive index greater than 1.45, and wherein the microlenses are randomly distributed, separating the second structured film with the micro-lens array from the first structured polymer film, and attaching the second structured film to a transparent substrate or cover of a light-emitting device through which light is emitted. Use of microlens arrays formed from relatively high surface energy materials enables matching refractive index of microlens array to that of light-emitting devices substrate or cover through which light is emitted and relatively high elastic modulus providing good scratch resistance. | 12-18-2008 |
| 20090169749 | INKS FOR HIGH SPEED DURABLE INKJET PRINTING - An inkjet ink composition comprising water, and at least one water-dispersible polyurethane/urea polymer having at least a first soft segment formed from a polyol prepolymer and at least a second soft segment formed from a polyamine prepolymer, wherein the polyol prepolymer forms urethane bonds in the polyurethane/urea and the polyamine prepolymer forms urea bonds in the polyurethane/urea, and further wherein at least about 4% by weight of the combined soft segments is formed by polyamine prepolymers that form urea bonds in the polyurethane/urea polymer. | 07-02-2009 |
| 20090170986 | PIGMENT-BASED INKS WITH IMPROVED JETTING LATENCY - An inkjet ink composition comprising water, pigment particles dispersed with a polymeric dispersant, at least one water-dispersible polyurethane, at least one pyrrolidinone compound, glycerol, and a 1,2-alkanediol having from four to eight carbon atoms. | 07-02-2009 |
| 20100055322 | Inkjet printing system and ink - An inkjet printing system comprises an inkjet printer responsive to digital signals and containing an ink composition comprising: | 03-04-2010 |
| 20100055323 | Inkjet printing system and fluorinated ink - An inkjet printing system, comprising an inkjet printer and an ink composition comprising:
