Composition, curable by visible light, useful for dental inlays and rapid prototypes, comprises a compound having an acrylate, methacrylate, vinyl or oxetan group or polysiloxane resin

摘要

A composition, curable by visible light, comprises 2-99 wt.% of a compound having an acrylate, methacrylate, vinyl, oxetan, acrylic-epoxy-oligomer and/or a methacrylic-epoxy-oligomer group and/or a polymerizable polysiloxane resin and 0.01-7 wt.% of an initiator. A composition (I), curable by visible light, comprises: (A) 2-99 wt.% of a compound having an acrylate, methacrylate, vinyl, oxetan, acrylic-epoxy-oligomer and/or a methacrylic-epoxy-oligomer group and/or a polymerizable polysiloxane resin; (B) 0.01-7 wt.% of an initiator; (C) 0-5 wt.% of a co-initiator; and (D) 0-85 wt.% of a modifier, preferably a filler, dye, pigment, flow additive, thixotrope, polymer-thickening agent, anti-oxidant, stabilizer or inhibitor. Independent claims are included for: (i) a process for the production of a tooth filling by layer-wise solidification of the composition (I) according to the cross-section of the filling; and (ii) an object prepared by curing of the composition (I) by visible light.
