Abstract: The invention relates to a radiation-curable silicone composition for additive-manufacturing technology comprising mercapto-functional polyorganosiloxane(s) as Component A, organosiloxane(s) with at least two aliphatic unsaturated carbon-carbon moieties as Component B, photo-initiator(s) as Component C for initiating a curing reaction between Component A and Component B, dye(s) as Component D dissolved in mercapto-functional polyorganosiloxane(s) as Component E, the mercapto-functional polyorganosiloxane(s) having a fraction of (mercaptoalkyl)methylsiloxane units of at least 50 mol %, wherein Component D is dissolved in Component E before Component D is combined with the other components of the radiation-curable silicone composition. The invention also relates to a process of producing a radiation-curable composition wherein the process comprises the steps of providing a solution of dye(s) in a composition comprising mercapto-functional polyorganosiloxane(s) having a fraction of (mercaptoalkyl)methylsiloxane units of at least 50 mol %, combining the solution containing the dye(s) dissolved in the mercapto-functional polyorganosiloxane(s) with mercapto-functional polyorganosiloxane(s), organosiloxane(s) with at least two aliphatic unsaturated carbon-carbon moieties, photo-initiator(s) for initiating a curing reaction between Component A and Component B, optionally filler(s), stabilizer(s) and additive(s).

Abstract: The invention relates to a process of taking a dental impression, the process comprising the steps of providing a radiation-curable dental impression composition, placing the radiation-curable dental impression composition in contact with dental tissue, applying radiation to the radiation-curable dental impression composition, letting the radiation-curable dental impression composition cure, removing the cured dental impression composition from the dental tissue, the radiation-curable dental impression composition comprising mercapto-functional polyorganosiloxane(s), VQM resin(s), photo-initiator(s) for initiating a curing reaction between, and optionally filler(s). The invention also relates to a cured dental impression obtained by radiation curing the radiation-curable dental impression composition, a kit of parts containing the radiation-curable dental impression composition and a dental impression tray filled with the radiation-curable dental impression composition.
