Claim 0:
1. A thermosetting material, comprising the following components (A) to (C) and at least one component selected from the group consisting of the following components (D) to (F):
(A) a (meth)acrylate compound in which a substituted or unsubstituted hydrocarbon group having at least 6 carbon atoms is ester-bonded, wherein a substituted or unsubstituted alicyclic hydrocarbon group having, at least 6 carbon atoms is at least one selected from the croup consisting of a substituted or unsubstituted adamantyl group and a substituted or unsubstituted isobornyl group, wherein the (meth)acrylate compound has a viscosity of from 5 to 300 mPa·s, when measured with a rotational viscometer at a constant shear rate by a method of JIS K7117-2:1999 at 25° C. and a shear rate of from 10 to 100 s−1;
(B) spherical silica,
(C) a black pigment,
(D) (meth)acrylic acid or a monofunctional (meth)acrylate compound having a polar group;
(E) a monofunctional (meth)acrylate compound other than the components (A) and (D); and
(F) a polyfunctional (meth)acrylate compound other than the component (A), wherein
wherein a content of the component (B) is from 79% to 90% by mass based on 100% by mass of a total of the components (A) to (F),
wherein a content of the component (C) is from 0.1% by mass to less than 1% by mass based on 100% by mass of a total of the components (A), (B), and (C),
wherein a total of the component (A), (D), (E), and (F) is from 1% to 20% by mass based on 100% by mass of the total of the components (A) to (F), and
wherein the thermosetting material has a viscosity of from 5 Pa·s to 200 Pa·s, when measured with a rotational viscometer at a constant shear rate by the method of HS K7117-2:1999 at 25° C. and a shear rate of 10 s−1; and a viscosity of from 0.3 Pa·s to 50 Pa·s, when measured with a rotational viscometer at a constant shear rate by the method of HS K7117-2:1999 at 25° C. and a shear rate of 100 s−1.
