Abstract: A composite material comprises: an open grid comprising at least two sets of strands. Each set of strands has openings between adjacent strands. The sets are oriented at a substantial angle to one another. A tack film is laminated to the open grid. The tack film has first and second major surfaces, such that a material of the tack film at its first and second major surfaces is a material including about 50% or more of resinous non-asphaltic component and about 50% or less of asphaltic component.

Abstract: An aqueous ink jet ink composition having a pigment wherein at least 50% of the pigment particles have an average diameter or size≦0.3 microns with the remaining particles in the ink composition having a diameter or size≦3.0 microns, water, a dispersant which is a reaction product of an aldehyde and a naphthalene sulfonate salt, and/or a sulfone solvent. The aqueous ink jet ink possesses a latency of at least 10 seconds at a relative humidity of 15% in either a high resolution (>360 spi) printhead or full-width array printhead having at least one nozzle opening of a diameter or size ranging from 10 to about 49 microns.

Abstract: Disclosed is an ink composition which comprises (a) water, (b) a surfactant of the formula wherein the molecular weight of the polypropylene oxide block is about 900 and the ethylene oxide blocks constitute about 80 percent by weight of the molecule, (c) colored pigment particles, and (d) uncolored precipitated colloidal silica particles, wherein the ink has a pH of at least about 7.5 when measured at about 25° C.

Abstract: An aqueous ink jet ink composition having a pigment wherein at least 50% of the pigment particles have an average diameter or size .ltoreq.0.3 microns with the remaining particles in the ink composition having a diameter or size .ltoreq.3.0 microns, water, a dispersant which is a reaction product of an aldehyde and a naphthalene sulfonate salt, and/or a sulfone solvent. The aqueous ink jet ink possesses a latency of at least 10 seconds at a relative humidity of 15% in either a high resolution (>360 spi) printhead or full-width array printhead having at least one nozzle opening of a diameter or size ranging from 10 to about 49 microns.

Abstract: Disclosed is a process which comprises incorporating into an ink jet printing apparatus an ink composition which comprises water, a colorant, and a polymer of the formula ##STR1## wherein m, n, x, and y are each integers representing the number of repeat monomer units, and wherein the ratio of x:y is from about 10:90 to about 90:10, and causing droplets of the ink to be ejected in an imagewise pattern onto a recording sheet.

Abstract: A microwave dryable thermal ink jet ink including an aqueous liquid vehicle, a co-solvent of formylethanolamine, acetylethanolamine, triethanolamine, trimethylolpropane, thiodiethanol, sulfolane and 1,3-dimethylimidazolidinone, a colorant, and ammonium bromide is described. Ammonium chloride may also be included in the microwave dryable ink so long as the ink also contains ethylene glycol as a second co-solvent. A method of forming an image on an image receiving substrate with a microwave dryable thermal ink jet ink of applying in imagewise fashion to the image receiving substrate by thermal ink jetting a microwave dryable thermal ink jet ink comprising formylethanolamine, acetylethanolamine, triethanolamine, trimethylolpropane, thiodiethanol and 1,3-dimethylimidazolidinone, a colorant, and ammonium bromide, and thereafter exposing the image receiving substrate to microwave radiation to dry the image on the substrate is also described.

Abstract: Several methods are provided for cleaning felt or foam materials that are used to store and deliver ink, particularly ink supplied to ink jet printheads in an ink jet printing system. The felt materials are contaminated during manufacture, by various antistats, primarily phosphates. These antistats later react with the ink to create kogation and nozzle blocking problems as well as reduction of surface tension of the ink. The methods of the invention are directed to reducing the antistats left in the storage material after manufacture. In one method, the material is washed in heated softened water. Prior to loading the material in the wash, IPA is added to the heated wash. The material is washed through two Wash/Rinse cycles and then dried. The removal of the calcium in the wash water via softening prevents the precipitation of calcium-phosphate salts, which, when the material later contacts the ink, reduces nozzle clogging caused by these precipitates.

Abstract: An apparatus for printing a multicolor image on a sheet movable along a sheet path in a process direction. The apparatus includes a first printhead mounted at a first location along the sheet path and containing a first type ink for printing a first portion of the image on the sheet in which the first type ink has a surface tension greater than 40 dynes/cm at room temperature. The apparatus also includes a set of secondary printheads mounted along the sheet path and separated a small gap from the first printhead. The set of secondary printheads each contains a secondary type ink for printing a secondary portion of the multicolor image on the sheet, and each of the secondary type ink has a surface tension less than 40 dynes/cm at room temperature.

Abstract: An aqueous ink jet ink composition includes a pigment and an aqueous carrier medium containing sulfolane and a low molecular weight polyethylene glycol. In preferred embodiments, the low molecular weight polyethylene glycol has a number average molecular weight between 350 and 650.

Abstract: A multi-color ink-jet printer in which a first partial image is created on a recording medium, and then a second partial image is created on the same recording medium after the first partial image is substantially dried. The first partial image comprises an ink which dries at a slower rate than that of the second partial image. In one embodiment, means are provided for heating the recording medium prior to the creation of the second partial image.
