PURPOSE: To obtain a flexible resin composition which can be rapidly cured with ultraviolet rays and can give a cured product having a high refractive index by mixing urethane (meth)acrylate and/or epoxy (meth)acrylate with a specified compound, an ethylenically unsaturated compound other than the above, and a photopolymerization initiator.
CONSTITUTION: The resin composition is prepared by mixing a urethane (meth) acrylate and/or an epoxy (meth)acrylate with a compound of the formula (wherein R1 and R2 are each H or CH3; Y1 to Y4 are each H or CH3; a and b are each a number of 1-10, and their sum is 2-10 on the average), an ethylenically unsaturated compound other than the above compounds, and a photopolymerization initiator. This composition is desirable in the production of a transmission screen.
