Abstract: Described herein is a dicarboxylic acid compound of formula (I): Wherein: R3 comprises an aryl group, R2 is an alkylene group comprising 1 to 6 carbon atoms, n is 0 or 1, R1 is H or CH3, and X is S or NZ, wherein Z is H, an alkyl group comprising 1 to 4 carbon atoms or a phenyl group. Such compounds can be used to modify the surface of inorganic particles. These modified inorganic particles may then be advantageously used in polymerizable resins to increase the refractive index of the resulting composite, while enabling good flow properties of the polymerizable composition.

For each angle of incidence in an incident angle range of 0-50 degrees, an optical transmittance of each of the optical film and the plurality of second layers versus wavelength includes a band edge disposed in a transition wavelength range separating a visible wavelength range where the optical film and the plurality of second layers have respective average optical transmittances Tv and Tv2 from an infrared wavelength range where the optical film and the plurality of second layers have respective average optical transmittances Ti and Ti2. Each of Tv and Tv2 is greater than about 30%. An average value of Tv2 is greater than an average value of Tv by at least 5%. An average value of Ti is less than an average value of Ti2 by at least 20%.

Abstract: A multifunctional polymerizable ionic liquid is described comprising an anion and a cationic group having at least two ethylenically unsaturated polymerizable groups, each bonded to the cationic group via a divalent non-alkyl linking group. The multifunctional linking groups independently comprise a heteroatom such as oxygen or nitrogen. The linking groups may independently comprise one or more linkages such as an amide, urea, and more typically a urethane or ester linkage. The ethylenically unsaturated polymerizable groups are typically (meth)acrylate groups. Coatings and coated articles are also described.
