    摘要: 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.

    摘要: A method of making an optically diffusive adhesive comprises: preparing a first adhesive composition comprising first particles dispersed in an optically clear adhesive matrix; determining a first haze and a first clarity of the first adhesive composition; and based upon the first haze and the first clarity, preparing a second adhesive composition that comprises the optically clear adhesive matrix, the first particles, and second particles dispersed in the optically clear adhesive matrix. An optically diffusive adhesive comprises first and second particles dispersed in an optically clear adhesive matrix is also disclosed. The first and second particles have a higher refractive index than the optically clear adhesive matrix. Articles comprising the optically diffusive adhesive are also disclosed.
