Abstract
a curable composition that gives a cured product exhibiting a high refractive index and a surface without defects such as roughness or cracks, a cured product of the composition, and a compound that may be blended to the composition. In a curable composition including a triazine compound having three aromatic-ring-containing groups each bonded to the triazine ring via an amino group, an aromatic-ring-containing group having a specific structure having a radically polymerizable group-containing group or a cationically polymerizable group-containing group is used as at least one of the three aromatic-ring-containing groups bonded to the triazine ring in the triazine compound mentioned above.
Claims8
A curable composition comprising a polymerizable heterocyclic compound (A) and an initiator (C),
- wherein the polymerizable heterocyclic compound (A) is a compound represented by the following formula (A1):
- wherein, in the formula (A1), RA1, RA2, and RA3 each are an aromatic-ring-containing group, at least one of RA2 and RA3 is a group represented by the following formula (A2):
- Wherein —NH— groups bonded to the triazine ring each are bonded to the aromatic ring in RA1, RA2, and RA3;
- in the formula (A2), Ra1 and Ra2 are each independently an alkyl group having 1 or more and 4 or less carbon atoms, an alkoxy group having 1 or more and 4 or less carbon atoms, or a halogen atom;
- n1 and n2 are each independently an integer of 0 or more and 4 or less;
- Ra3 and Ra4 are each independently a hydrogen atom, an alkyl group having 1 or more and 4 or less carbon atoms, a halogenated alkyl group having 1 or more and 4 or less carbon atoms, or a phenyl group;
- Ra3 and Ra4 may be bonded to each other to form a ring;
- RA4 is a radically polymerizable group-containing group or a cationically polymerizable group-containing group;
- and
- when RA2 and RA3 each are a group represented by the formula (A2), RA2 and RA3 each have a radically polymerizable group-containing group or each have a cationically polymerizable group-containing group.
