A method to prepare an oligomer which includes a plurality of pendent alkenyl groups, where the method reacts a copolymer formed by copolymerizing styrene and allyl alcohol comprising a polyhydroxy oligomer wherein n is between about 3 and about 50, and having a structure:

##STR00001##

with an isocyanate having a structure:

##STR00002##

##STR00001## wherein R.sup.102 represents a crosslinking group.

The present invention is directed to a process for preparing light curable energetic polymeric binders. The process for preparing such binder comprises the steps of mixing a pre-polymer such as PGN or GAP having a terminal hydroxyl group with a solvent and adding reactants wherein the reactant has a light curable moiety and a pre-polymer reactive moiety. Catalysts such as carbodiimide and DMAP may be further added to the mixture.

In one embodiment, a photocurable composition can comprise a polymerizable material and a photoinitiator, wherein the polymerizable material includes an isocyanate group containing compound of formula (1): R1-R2-N═C═O (1), with R1 including a carbon-carbon double bond, and R2 being substituted or unsubstituted alkyl, aryl, or alkylaryl. An amount of 1 wt % to 10 wt % of the isocyanate group containing compound can cause a strong adhesion strength of the photocurable composition to a silicon substrate after curing, and may allow the omission of an adhesion layer between substrate and the photo-cured layer.

An electrophotographic photosensitive member, which is suppressed in occurrence of fogging and is excellent in abrasion resistance. In the electrophotographic photosensitive member, an outermost surface layer of the electrophotographic photosensitive member comprises a polymerized product of a composition comprising at least a polyrotaxane and a monomer having a polymerizable reactive group, and a chain molecule of the polyrotaxane has two blocking groups at both terminals thereof, and a (meth)acryloyloxy group of a cyclic molecule of the polyrotaxane forms a bond.
