Abstract:
The invention relates to a coloured curable composition for use in an additive manufacturing process, the composition comprising a curable resin composition comprising radiation curable components, a photo initiator, a dye composition comprising a dye D1 and a dye D2, dye D1 having a light absorption maximum within a wave length range from 400 to 530 nm, dye D2 showing a light absorption maximum within a wave length range from 540 to 650 nm. The invention also relates to a 3-dim composite article obtained by processing the curable composition in an additive manufacturing process.
