A resin composition comprises a urethane (meth)acrylate oligomer. The resin composition has a storage modulus of about 2×10.sup.3 Pa to about 2×10.sup.4 Pa when irradiated with 200 mJ/cm.sup.2 of an ultraviolet light.

The present invention relates to an anaerobically curable impregnation sealant composition and methods thereof containing a (meth)acrylic monofunctional monomer with a hydrophobic moiety, a (meth)acrylic monofunctional monomer with a hydroxyl group, a modified polyester urethane methacrylate resin having a weight average molecular weight of from about 8000 to about 18000 g/mol, and triallylisocyanurate, triallylcyanurate, or derivatives thereof, or a combination thereof. The present invention particularly relates to a sealant composition for impregnation to plastic and metal substrates that also provides resistance to thermal cycling.

The disclosure provides recording materials include fluorene derivatized monomers and polymers for use in volume Bragg gratings, including, but not limited to, volume Bragg gratings for holography applications. Several fluorene structures are disclosed: simply substituted fluorenes, cardo-fluorenes, and spiro-fluorenes. Fluorene derivatized polymers in Bragg gratings applications lead to materials with higher refractive index, low birefringence, and high transparency. Fluorene derivatized monomers/polymers can be used in any volume Bragg gratings materials, including two-stage polymer materials where a matrix is cured in a first step, and then the volume Bragg grating is written by way of a second curing step of a monomer.
