    Abstract: The invention provides stable dispersions of couplers and methods of their formation. The stable dispersions are formed by the use of a nonionic water soluble polymer in combination with an anionic surfactant having a sulfate or sulfonate head group and a hydrophobic group of 8 to 20 carbons. The preferred nonionic water soluble polymers are polyethyleneoxide and polyvinylpyrrolidene.

    Abstract: A method of manufacturing a micro-lens array and light-emitting device, comprising forming a first structured polymer film with close packed surface cavities having a mean diameter of less than 20 micrometers and a relatively lower surface energy surface, forming a transparent second structured film with an array of microlenses formed thereon corresponding to the cavities of the first structured film, wherein the second structured film comprises a relatively high surface energy material and has a refractive index greater than 1.45, and wherein the microlenses are randomly distributed, separating the second structured film with the micro-lens array from the first structured polymer film, and attaching the second structured film to a transparent substrate or cover of a light-emitting device through which light is emitted. Use of microlens arrays formed from relatively high surface energy materials enables matching refractive index of microlens array to that of light-emitting devices substrate or cover through which light is emitted and relatively high elastic modulus providing good scratch resistance.
