Claim Text:
1. A process for producing a dental shaped part, which process comprises curing a composite resin composition comprising (a) at least one polyreactive binder, (b) a first photopolymerization initiator having an absorption maximum at a wavelength of less than 400 nm, (c) a second photopolymerization initiator having an absorption maximum at a wavelength of at least 400 nm and (d) an absorber having an absorption maximum at a wavelength of less than 400 nm, by means of stereolithography, wherein (i) the composite resin composition is cured in layers by the local introduction of radiation the emission maximum of which is at a wavelength of less than 400 nm to form a three-dimensional body, and (ii) the obtained three-dimensional body is further cured by the introduction of radiation the emission maximum of which is at a wavelength of at least 400 nm.
