    摘要: An object of the present invention is to provide a photocurable resin composition having excellent thick-film curability and further excellent storage stability, and a cured product of the photocurable resin composition has a high concealing effect.
    The present invention is a photocurable resin composition containing components (A) to (E):
    a component (A): a leuco dye;
    a component (B): a photoacid generator;
    a component (C): a radical polymerizable compound (except for a (meth)acrylate having a tertiary amine skeleton);
    a component (D): a photoradical polymerization initiator; and
    a component (E): a tertiary amine compound.

    摘要: Color and/or opacity changing liquid radiation curable resins are herein described, along with methods for using the same in additive fabrication processes. Described and claimed are methods for improving additive fabrication build processes by controlling, at least temporarily, the depth of penetration of a liquid radiation curable resin. The liquid radiation curable resins herein described are capable of curing into three-dimensional articles having a certain amount of color and/or opacity. The resulting three-dimensional articles possess an ability to further change in color and/or opacity, and possess excellent mechanical properties. Also herein described are the three-dimensional articles formed according to the methods of the invention.
