Claim:
1. A recording medium comprising an oleophilic substrate and, thereover, a topmost oleophobic layer comprising a cured polymeric silicone matrix that consists essentially of the addition-cure reaction product of a vinyl-functional polydialkylsiloxane and a silane cross-linking agent, and further comprising a laser-ablatable imaging layer between the substrate and the topmost layer, wherein: a) the vinyl-functional polydialkylsiloxane has a molecular weight ranging from 30,000 to 75,000 or 110,000 to 130,000; b) if the molecular weight of the vinyl-functional polydialkylsiloxane is within the range of 30,000 to 75,000, a molar ratio of silane groups in the cross-linking agent to vinyl groups in the polydialkylsiloxane is within the range of about 11:1 to about 25:1; and c) if the molecular weight of the vinyl-functional polydialkylsiloxane is within the range of 110,000 to 130,000, the molar ratio of silane groups in the cross-linking agent to vinyl groups in the polydialkylsiloxane is from about 5:1 to about 27:1 and further wherein the imaging layer (i) has a thickness no greater than 50 nm, (ii) is a thin metal/metal oxide layer and (iii) is ablatable upon exposure to a laser beam having a fluence of at least 250 mJ/cm
