Abstract
The invention relates to a method for forming a liquid radiation curable resin capable of curing into a solid upon irradiation comprising at least one thermally sensitive visual effect initiator. The liquid radiation curable resin is capable of curing into three-dimensional articles having selective visual effects. The resulting three-dimensional articles possess excellent color and/or transparency stability and excellent mechanical properties.
