THERMAL SUBLIMATION PAPER, METHOD FOR THE PRODUCTION THEREOF AND USE THEREOF
The invention relates to a thermal sublimation paper which can be printed with inks containing a sublimatable dye, in particular ink-jet inks, in which paper a hydrophilic thermal transfer layer to be printed is formed on a porous base paper. Thermoplastic particles with an average particle size of between 0.3 and 5 μm and a melting point of between 35° C. and 190° C. are present in the thermal transfer layer. This thermal sublimation paper can be advantageously produced as follows: an aqueous coating slip is applied to a porous base paper having a Cobb value of between 55 and 150 g/m.sup.2, in particular between 70 and 150 g/m.sup.2, in a paper-making or coating machine, online or offline, said aqueous coating slip containing thermoplastic particles and constituents suitable for forming a hydrophilic thermal transfer layer, and a drying step is subsequently carried out in order to obtain the thermal sublimation paper. The thermal sublimation paper can be used advantageously to mint flat materials, in particular films and textiles.
PRE-TREATMENTS FOR PUBLISHING PRINT MEDIA
A pre-treatment coating composition can include an evaporable liquid vehicle and a pre-treatment coating matrix carried by the evaporable liquid vehicle. The pre-treatment coating matrix in this example can include from 30 wt % to 70 wt % multivalent organic salt including a multivalent metal acetate or a multivalent metal propionate, from 5 wt % to 30 wt % dispersed polymeric binder having a weight average molecular weight from 20,000 Mw to 1,000,000 Mw, from 0.5 wt % to 8 wt % of a high molecular weight polyvinyl alcohol binder, and from 10 wt % to 30 wt % of a low molecular weight polyvinyl alcohol binder. The low molecular weight polyvinyl alcohol binder and the high molecular weight polyvinyl alcohol binder in this example can be present in the pre-treatment coating matrix at a 3:1 to 15:1 weight ratio. Weight percentages in this example are based on dry weight of the pre-treatment coating matrix.
