PURPOSE: To obtain the subject new monomer rapid in curing with UV light, good in adhesivity to back sheets not treated with primers, and useful for cured products excellent in mold releasability, shape reproducibility, abrasion resistance, etc., especially transmission type screens.
CONSTITUTION: The monofunctional monomer is the reaction product of (A) a compound of formula I (e.g. 3- or 4-isopropenyl-α,α-dimethylbenzylisocyanate) with (B) a compound having a hydroxyl group bound to an aliphatic carbon atom in the molecule [e.g. methanol, ethanol, 6-(perfluoroethyl)hexanol]. For example, a monomer of formula II. The cured product of a resin composition containing the monofunctional monomer, a (meth)acrylate compound and a photopolymerization initiator such as a compound of formula III is useful for Fresnel lenses used for video projectors, etc. The component B is used in an amount of about 1-10 moles per equivalent of the isocyanate group of the component A.
