Title:

CURING COMPOSITION

Document Type and Number:

Japanese Patent JP2002206010

Kind Code:

A

Abstract:

To provide a fluorine-based, actinic energy radiation-curing composition which has a low refractive index, high strength and high durability at the same time, and which is useful in various optical usages and has excellent transparency.

The actinic energy radiation-curing composition contains a monomer (A) expressed by general formula (I) CH2=C(R1)COO(CH2)k(ClF2l)(CH 2)kOOCC(R1)=CH2...(I) (wherein, k is 1 or 2; l is an integer of 1-20; and R1 is H, CH3, F or Cl) and a monomer (B) having a (meth)acryloyl group other than the monomer (A). A cured material of the composition has a refractive index of ≤1.45 and a Shore hardness of ≥D80.
