To obtain the subject composition capable of forming a coating film having excellent wear resistance and fogging resistance when irradiated with an active energy ray by including a polyglycerol derivative having a specific structure.
This composition comprises a polyglycerol derivative having a structure of formula I {R1 is a group of formula II or formula III [X is (meth) acrylate or (meth)acrylate terminal acyloxy]; R2 and R3 are each H or a group of formula II or formula III), containing a hydroxyl group in the molecule in which ≥50% of the main change end and the side chain end are (meth) acrylate groups and the rest is an epoxy group in the composition. Preferably the composition contains a reactive surfactant such as an alkylallyl sulfosuccinate, etc. The composition is applied to various synthetic resin molding products preferably in 3-15 μm thickness and irradiated with an active energy such as ultraviolet light so that a coating film having excellent wear resistance and fogging resistance can be formed.
