ABSTRACT:
Substrates, e.g., silicon wafers, coated with a UV-curable organopolysiloxane composition including a crosslinking catalyst therefor (e.g., a platinum group metal compound) and an amount of a crosslinking inhibitor (e.g., an azodicarboxylate) which is effective at ambient temperature, but ineffective to prevent crosslinking on exposure of the composition to ultraviolet radiation, are well adapted for the imaging of negative intelligence patterns thereon.
