Abstract: Presently described are optical films comprising a polymerized (e.g. microstructured) surface that comprises the reaction product of a polymerizable resin composition and polymerizable resin compositions that comprise nanoparticles; at least one first monomer comprising at least two (meth)acrylate groups; and at least one second (meth)acrylate monomer having the structure wherein at least one R1 comprises an aromatic substituent, t is an integer from 1 to 4, and R2 is hydrogen or methyl.

Abstract: A multipurpose anchor assembly includes a block assembly for mounting to the upper sidewall of a cargo carrying vehicle to accommodate tie down of handled cargo. A pin is received through an aperture in the block and engages a spring mounted plate assembly which allows for engagement of the pin for locking in selective positions. The pin includes an eye formation at a top thereof to facilitate attachment of a tie down lashing member.
