20130337260 | METHODS FOR PREPARING OPTICALLY CLEAR ADHESIVES AND COATINGS - Optically clear adhesive or coating layers can be prepared by preparing a curable mixture, coating the curable mixture to form a layer, partially curing the curable mixture, drying the coated layer, and fully curing the curable mixture. The curable mixture may also be partially cured and then coated, dried and fully cured. The curable mixture includes two free radically polymerizable monomer compositions that are relatively incompatible and a transient compatibilizer, such as a solvent. Polymers of the two monomer compositions, if polymerized separately and blended, form phase separated domains. The curable mixture provides for adhesive or coating layers that are optically clear. | 12-19-2013 |

20140106267 | METHOD OF FORMING AN IMAGE HAVING MULTIPLE PHASES - A method of forming an image having multiple phases is disclosed herein. The method includes forming exposed and unexposed areas, the exposed areas comprising a first polymer network exhibiting first and second phases that are chemically connected and have different refractive indices, the first phase being continuous, and the second phase comprising a plurality of structures dispersed within the first phase, and the unexposed areas comprising a second polymer network comprising third and fourth phases that are chemically connected and have different refractive indices, the third phase being continuous, and the fourth phase comprising a plurality of structures dispersed within the third phase. The first and second polymer networks are chemically connected, and morphology formed by the first and second phases is different than that formed by the third and fourth phases. | 04-17-2014 |
20140169029 | BEADED CLEAR OPTICAL LAYERS FOR TURNING OR EXTRACTING LIGHT - Optical films performing the function of turning or extraction are described. More specifically, beaded clear layers having first and second layers of pressure sensitive adhesive and a plurality of microspheres are described. In some embodiments, the thicknesses of the first and second layers of pressure sensitive adhesive and the diameter of the microspheres are selected such that the first and second layers of pressure sensitive adhesive are not in contact. In other embodiments, the index of refraction of the microspheres is selected to reflect light through total internal reflection. Optical films with beaded clear layers and light extraction layers are also described. | 06-19-2014 |
20140248458 | MICROSTRUCTURED TRANSFER TAPES - Transfer tapes include an optically transparent adhesive layer with a first major surface and a second major surface, with at least one of the major surfaces including a microstructured pattern that is a permanent feature of the adhesive surface. The microstructured surface alters the direction of light. The optically transparent composition may include a low Tg polymeric component with a Tg of less than 20° C., and an acid or base functionality, and a high Tg polymeric component with a Tg of greater than 20° C., and an acid or base functionality, such that the functionality of the low Tg polymeric component and the functionality of the high Tg polymeric component form an acid-base interaction when mixed. The transfer tapes can be adhered to substrates to provide a microstructured surface to the substrate surface. | 09-04-2014 |
