Abstract: A multilayer optical film including a first layer having an index of refraction n1 at a wavelength λ in a range from about 580 nm to about 650 nm, and a second layer having an index of refraction n2 at λ is described. The first and second layers define an interface therebetween comprising a two-dimensional grating. The grating may have an average height H such that |n1−n2|*H is in a range from 0.24 micrometers to 0.3 micrometers. Optical systems including the multilayer optical film are described. A subpixel in a display surface of the optical system may be diffracted into a zero diffraction order and a plurality of first diffraction orders where the intensities of the zero and first diffraction orders are with 10% of each other at λ. The optical system may have a modulation transfer function greater than 0.4 at 10 line pairs per millimeter.

Abstract: According to various embodiments of the present disclosure, a composition includes about 5 to about 40 parts by weight of a solute copolymer component. The solute component optionally has one Tg or Tm of at least 25° C. The composition further includes about 60 to about 95 parts by weight of a solvent monomer. The solvent monomer component includes (meth)acrylate monomers and a multifunctional acrylate. The sum of the solute copolymer component and the solvent monomer component is 100 parts by weight. The composition further includes about 5 to about 100 parts of a plasticizer, relative to the 100 parts.
