摘要:
The partial alkylation of a polyhydroxybenzophenone having ortho- and para-hydroxy substituents to form an ortho-hydroxy, para-alkoxy benzophenone is carried out in the presence of a non-aqueous solvent, viz. a polyethylene glycol or its mono or dialkylated derivatives, whereby high yields of alkylated product are obtained in shorter reaction times.

Various patterning methods utilize certain crosslinkable reactive polymers comprise -A- and -B- recurring units, arranged randomly along a backbone. The -A- recurring units comprise pendant aromatic sulfonic acid oxime ester groups that are capable of providing pendant aromatic sulfonic acid groups upon irradiation with radiation having a λmax of at least 150 nm and up to and including 450 nm. The -A- recurring units are present in the reactive polymer in an amount of up to and including 98 mol % based on total reactive polymer recurring units. The -B- recurring units comprise pendant groups that provide crosslinking upon generation of the aromatic sulfonic acid groups in the -A- recurring units. The -B- recurring units are present in an amount of at least 2 mol %, based on total reactive polymer recurring units.

An inkjet printing system, comprises: a printer, a pigment ink composition, and a dry recording media supply for receiving ink, the media comprising a support bearing an ink-receiving layer containing a complex of a polyvalent metal cation and a ligand, wherein the complex has a stability constant, K1, in the range of 0.3 to 6.0. The system gives images with excellent gloss, coalesence, and image quality.
摘要:
A method of printing on an inkjet recording element having a support having thereon in order: a) a porous upper fusible layer of fusible polymeric materials and a binder, b) a porous ink-receiving layer in which pigmented ink is stratified such that, after fusing the printed element, greater than 50% of the printed pigment colorant particles in the inkjet ink composition is retained in the bottom half of the upper porous fusible layer.
摘要:
An inkjet recording element comprising, over a porous, ink-receiving layer, a fusible, porous topmost layer comprising a film-forming, hydrophobic binder and fusible, polymeric particles of a non-segmented polyurethane, or salt thereof, comprising repeat units derived from a diisocyanate and a diol component comprising a mixture of diols, said diol mixture comprising: an anionically-substituted diol selected from carboxylic acid-, sulfonic acid-, and phosphonic acid-substituted diol and an ether containing short chain aliphatic diol, wherein the polyurethane has a Tg greater than about 70° C.

Crosslinkable reactive polymers comprise -A- and —B— recurring units, arranged randomly along a backbone. The -A- recurring units comprise pendant aromatic sulfonic acid oxime ester groups that are capable of providing pendant aromatic sulfonic acid groups upon irradiation with radiation having a λmax of at least 150 nm and up to and including 450 nm. The -A- recurring units are present in the reactive polymer in an amount of greater than 50 mol % and up to and including 98 mol % based on total reactive polymer recurring units. The —B— recurring units comprise pendant groups that provide crosslinking upon generation of the aromatic sulfonic acid groups in the -A- recurring units. The —B— recurring units are present in an amount of at least 2 mol %, based on total reactive polymer recurring units. These reactive polymers can be used in various pattern-forming methods.
摘要:
An inkjet recording element comprises a support having thereon at least one ink-receiving layer, including a porous fusible layer comprising fusible polymeric particles and a thermoresponsive polymer that is capable of exhibiting a lower critical solution temperature below 20° C.
摘要:
An inkjet recording element having a support having thereon in order: a) a fusible, porous ink-receptive layer of fusible polymeric particles and a binder; b) a fusible, porous ink-transporting layer of fusible, polymeric particles and a film-forming, hydrophobic binder. The invention is also directed to an inkjet printing process wherein the ink-receptive layer and/or the support, each either alone or in combination, is capable of receiving substantially all of the ink carrier liquid received after the ink carrier liquid has passed through the ink-receptive layer.
摘要:
A method of selectively producing a glossy or matte finish to an ink jet printed image by applying a clear protective plastic laminate having a glossy finish to the surface of the image, heating the laminate to soften it and then selectively impressing a surface texture into the soften laminate. Pressing the softened laminate against an endless belt having a textured surface forms the surface texture. The laminate is maintained in contact with the belt for a cooling period so as to permit a cold separation of the laminate from the belt.
