Abstract:
Stray light absorbing films are described. In particular, stray light films including a black substrate, and first and second sets of microstructures are described. The described films can reduce stray light reflections in sensor modules and other optical devices.
Abstract:
Optical films are described having a polymerized microstructured surface that comprises the reaction product of a polymerizable resin composition comprising at least one polymerizable ethylenically unsaturated triphenyl monomer. Also described are certain triphenyl (meth)acrylate monomers and polymerizable resin compositions.
Abstract:
The composition includes an antimicrobial monomer represented by formula CH2═C(R1)—C(O)—O-Q-N+(R)2CnH2n+1(X—), a non-fluorinated crosslinking monomer having at least two acrylate groups, methacrylate groups, or a combination thereof, a polar monomer having at least one of acrylic acid, methacrylic acid, or a carboxylate salt thereof, and a nonpolar monomer represented by formula CH2═C(R1)—C(O)—O—R2. The antimicrobial monomer, the non-fluorinated crosslinking monomer, the polar monomer, and the nonpolar monomer together account for greater than 95 percent by weight, based on the total weight of the composition. The article includes a film having a plurality of pendent groups represented by formula —C(O)—O-Q-N+(R)2CnH2n+1(X—) covalently bonded in a crosslinked non-fluorinated acrylic network. A method of making an article is also described.

Abstract:
Stray light absorbing films are described. In particular, stray light films including a black substrate, and first and second sets of microstructures are described. The described films can reduce stray light reflections in sensor modules and other optical devices. The first set of microstructures can have an average largest diameter between 0.5 and 125 μm. The second set of microstructures can have an average largest diameter of less than ½ of the average largest diameter of the first set of microstructures. The stray light absorbing film can have a specular reflectance for 8° incidence for wavelengths from 350-1200 nm of less than 0.3%.

Abstract:
Presently described are optical films, such as a brightness enhancing film, having a polymerized microstructured surface disposed on a preformed polymeric film wherein the film has a thickness of no greater than 3 mils and the polymerized microstructured surface consists of the reaction product of a substantially non-brominated polymerizable resin composition.
Abstract:
A method of making optical films having a polymerized microstructured surface are described. The polymerized microstructured surface comprises the reaction product of a polymerizable resin composition comprising 10% to 100 wt-% of at least one biphenyl di(meth)acrylate monomer. The di(meth)acrylate monomer comprises a core biphenyl structure having two aromatic rings connected with a C—C bond. The biphenyl di(meth)acrylate monomer preferably comprises a sufficient amount of ortho and/or meta(meth)acrylate substituents such that the monomer is a liquid at 25° C.
