Description

  The present invention is a polymerizable compound that is polymerized or cured by light or heat, such as a pharmaceutical, agricultural chemical, coating agent, ink, paint, adhesive, resist, plate making material, oxygen atom-containing polycyclic compound, polymerization The present invention relates to a composition and a cured product thereof.

  Polymerizable compounds that are polymerized or cured by light or heat are widely used as polymer raw materials for coating agents, inks, paints, adhesives, resists, platemaking materials and the like. Conventionally, an epoxy compound has been used as a polymerizable compound in order to obtain a cured product having excellent chemical resistance and adhesion. However, since the epoxy compound has low polymerization reactivity (curability) and extremely high skin irritation and toxicity, safety in handling is regarded as a problem. On the other hand, vinyl ether compounds are attracting attention as polymerizable compounds having low toxicity and skin irritation, excellent safety, and excellent curability. However, in the market, since vinyl ether compounds are few in kind and expensive in price, the present situation is that they cannot sufficiently meet the needs.

  On the other hand, JP-A-10-25262 and JP-A-2003-73321 disclose several alicyclic vinyl ether compounds. Although these compounds are improved in workability in terms of low skin irritation, when these compounds are used as coatings or ink materials, the curing rate and hardness are insufficient and improvement is required.

Japanese Patent Laid-Open No. 10-25262 JP 2003-73321 A

An object of the present invention is to provide a novel oxygen atom-containing polycyclic compound, a polymerizable composition containing the same, and a cured product thereof.
Another object of the present invention is to provide an oxygen atom-containing polycyclic compound capable of forming a cured product having a high curing rate and high hardness, a polymerizable composition containing the same, and a cured product thereof.

  As a result of intensive studies to achieve the above object, the present inventors have found that when a vinyl ether compound having an oxygen atom-containing polycyclic group in the molecule is used as a comonomer of the polymer, the curing rate is remarkably improved and the hardness is increased. The present invention was completed by finding that a cured product having a high hardness was obtained.
