Zusammenfassung:	The present disclosure provides for a light diffusing pressure sensitive adhesive and a method of making the same. In applications where there is a point light source such as a light bulb or an light emitting diode (LED), or a series of such point light sources, and it is desirable to diffuse the light from the point source to produce a desirable background brightness. The light diffusive PSA disclosed herein is reworkable; has a luminous transmission of grater than 80%, as measured according to ASTM D 1003-95-5; has a haze value not less than 20%; and has a depolarization of less than about 10%, as measured using wavelength in the visible spectrum.
