POLYMERIZABLE COMPOSITION AND NOVEL ALKYNE COMPOUND

摘要

The polymerizable composition of the invention contains an alkyne compound represented by general formula (1). In general formula (1), X¹ and X² represent a sulfur atom, oxygen atom, or NH group, and each may be the same or different. Q represents a C1-2 alkylene group, carbonyl group, or thiophenylene group in which one carbon atom has been replaced by an antimony atom. R¹ and R² represent a C1-2 alkylene group, and each may be the same or different. m and n each represent 0 or 1.
