Abstract

To provide a transparent resin which is suitable in the process of producing a coating for electronic materials, a glass having both of the scattering-preventing function and the antireflective function, an adhesive agent, a shock-absorbing material, an ultraviolet-cutting sheet for televisions, a filter for VDTs and a high refractive index primer composition as well as the process for the production of primer-coated lenses using said primer composition, is excellent in a coatability, adhesive property, storage stability, durability, shock resistance and the like, and is particularly excellent in a transparency and adhesive property after curing of the same.

A transparent resin having an adhesive property characterized by comprising a cured product of the polymerizing composition which comprises at least one of diallyl phthalate, diallyl isophthalate and diallyl terephthalate, and pentaerythritol tetra(3-mercaptopropionate).

Claims
