There is provided a method for preparing a biaxially oriented polyester sheet or web, with improved antistatic properties, comprising the steps of(i) stretching said polyester sheet or web first in one direction and second in a direction perpendicular thereto(ii) coating said hydrophobic polyester sheet or web, either before stretching or between said first and second stretching operation, on one or both sides, with a transparent antistatic primer layer, wherein the coating composition of said transparent antistatic primer layer comprises (1) a dispersion of a polythiophene with conjugated polymer backbone and a polymeric polyanion compound and (2) a latex polymer having hydrophilic functionality.The primer layer is coated from an aqueous composition and does not show a substantial change in resistivity depending on relative humidity or wet processing.
摘要:
A method is disclosed for removing ink accepting areas of a printing surface of a lithographic printing master by treatment with an atmospheric plasma. Preferably, the plasma is directed to the printing surface as a plasma jet while the printing master is mounted on the plate cylinder of a printing press. The method enables to clean a support of a printing master and then reuse the cleaned support for making another printing master. Preferably, all the following steps are performed on-press: (i) making an imaging material by providing a support with an image recording layer; (ii) making a printing master having a printing surface comprising ink accepting areas by image-wise exposing and optionally developing the imaging material; (iii) starting a pressrun; (iv) a cleaning step using an atmospheric plasma and then repeating steps (i) to (iv).

An ink-jet printing system including at least one ink-jet ink and a means for jetting an ink-jet ink onto a surface of a substantially non-absorbing ink-jet ink-receiver, characterized in that the ratio σ Sd/σ Ld of the dispersive surface energy of said ink-receiver surface σ Sd over the dispersive surface energy of said ink-jet ink σ Ld is greater than 0.9. A process for ink-jet printing is also claimed. High areal throughput ink-jet printing (e.g. >100 m2/hour) with curable inks can be performed on different kinds of ink-receiver surfaces with a good image quality and colour density due to a controlled spreading of the ink-drops which can be directly cured.
