Abstract: A composition comprising polymeric particles having an average particle diameter from 0.5 to 30 ?m and Vicker's scale hardness from 100 to 700 Kgf/mm2. The composition also contains a film-forming polymer having Tg no greater than 80° C. The average refractive index difference measured from 400 nm to 1100 nm between the polymeric particles and the film-forming polymer is no greater than 0.04.

Abstract: Provided are methods of forming multi-layered optical data storage media which include a high-density data layer, as well as multi-layered optical data storage media that can be formed by such methods.

Abstract: A method for producing a photovoltaic module by contacting at least one layer of liquid encapsulant and a plurality of solar cells. The liquid encapsulant has two components. The first component is an acrylic polyol having a terminal hydroxy group, an average number of hydroxy-functional monomer units per polymer chain from 2 to 25 and Mn from 1,000 to 10,000. The second component is an aliphatic polyisocyanate with an average functionality of at least two. The molar ratio of non-terminal hydroxy groups in the polyol to isocyanate groups in the aliphatic polyisocyanate is from 0.5:1 to 1:0.5.
