摘要:
An ink composition for a meltable ink usable in printing apparatus in which ink droplets are ejected from ink ducts, the ink composition containing an amorphously solidifying monomer compound, which compound shows a crystallinity of less than 1 % when a melt of the compound is cooled at a rate of 5°C/min to past its solidification path and is then heated at a rate of 20°C/min to above its melting temperature. A compound of this kind can be used in a binder for the ink composition. When inks of this kind are transferred to a receiving material, it results in greater stability in printed layers, in respect of gum, scratch and fold resistance and transparency.
摘要:
A digital image processing apparatus is provided with means for offering, for selection by an operator, at least one digital image data file for the purpose of further handling, e.g. printing. A file of this kind can be protected by means of a code which must first be input by the operator before the apparatus releases the file. If a number of files thus protected are selected and processed either together or in series by an operator, after the first file the apparatus first tries out for each subsequent file whether the code applicable for the preceding file is also valid for the new file. If so, the apparatus releases the file immediately, whereas otherwise it asks for a code again.
摘要:
A water-insoluble liquid-absorbent material comprising a cross-linked matrix containing a polymer having at least two cross-linkable functional end groups and substantially free of cross-linking functional groups elsewhere within the polymer that are crosslinked with a cross-linking agent having a functionality greater than two, and in combination therewith, a dye-fixing agent having at least one reactive functional group. An ink jet recording medium having a coating of the water-insoluble liquid-absorbent material on a surface thereof is also provided.
摘要:
An opaque pressure sensitive adhesive (PSA) sheet or tape article, which comprises an anti-static coating on one side of a polymeric base film and an adhesive coating on the other side of the base film which can be opaque or transparent. If the base film is transparent, an opaque adhesive is coated onto the film to make it opaque. However, a clear adhesive can be coated onto the base film to make an opaque pressure sensitive adhesive tape if the base film itself is opaque. The total thickness of the pressure sensitive tape ranges from about 0.4 mil to about 1.8 mil with a base film thickness no greater than about 1.4 mil. The pressure sensitive tape should have an opacity of greater than or equal to about 70%. The resistivity of the prepared sheet having an anti-static coating layer thereon should not be larger than about 10 12 Ω/SQ.
