Abstract (en)

[origin: EP0806304A1] The transfer surface for a liquid product of greater or lesser viscosity, e.g. ink, onto a support such as paper consists of a substrate (1) with separate zones (2-4) of an anti-adhesive material (2), a hydrophilic material (3) and a hydrophobic material (4), or a combination of such zones designed to give the surface a heterogenous structure to improve the quality of liquid transfer to the support. The anti-adhesive material is of silicone, the hydrophilic material is a polymer with lateral acid groupings, and the hydrophobic material is a non-polar or fluoridated polymer, applied in various ratios, e.g. 5 to 10 per cent, 30 - 45 per cent and 50 - 60 per cent respectively. They can be applied, after coating the substrate with monomers or oligomers, by irradiation through a mask with opaque and transparent sections, using ultraviolet radiation and at least one initiator. The substrate can be made, for example, from a carboxylated nitrile elastomer, a polyolefin or formulated polyurethane.
