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. A triazine compound is used as a curable component in a curable composition, the triazine compound having an optionally substituted quinolinyl group, an optionally substituted isoquinolinyl group, or an optionally substituted 2-substituted benzothiazolyl group and an aromatic-ring-containing group having a radically polymerizable group-containing group or an aromatic-ring-containing group having a cationically polymerizable group-containing group, each group bonded to the triazine ring via an amino group.
Claims6
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 RA1 is an optionally substituted quinolinyl group, an optionally substituted isoquinolinyl group, or a 2-substituted benzothiazolyl group as RA1, the 2-substituted benzothiazolyl group having a group represented by —S—RA0 at the 2-position, wherein RA0 is a hydrogen atom, a radically polymerizable group-containing group, or a cationically polymerizable group-containing group;
- wherein the 2-substituted benzothiazolyl group as RA1 may have a substituent other than the group represented by —S—RA0 at a position other than the 2-position, RA2 and RA3 each are an aromatic-ring-containing group having a radically polymerizable group-containing group or an aromatic-ring-containing group having a cationically polymerizable group-containing group;
- and —NH— groups bonded to the triazine ring are each bonded to the aromatic ring in RA2 and RA3.
