The present invention relates to a pressure-sensitive adhesive sheet including a pressure-sensitive adhesive layer containing a base polymer and a pigment, the pressure-sensitive adhesive sheet having a transmittance for light having wavelengths of 380-600 nm of 25% or less, transmittance for light having wavelengths 800-2,500 nm of 60% or greater, and a change in light transmittance in the wavelength range of 600 to 800 nm of 0.1%/nm or greater.

A moisture-curable composition is shown and described herein. The moisture-curable composition comprises a moisture-curable resin and a moisture scavenger selected from a cyanoalkylalkoxysilane. The inclusion of the cyanoalkylalkoxysilane in the moisture-curable composition has been found to effectively scavenge moisture and control the rate of curing and viscosity increase in the composition.

The PSA sheet provided by this invention has a PSA layer. The PSA layer comprises particles P.sub.HRI. The particles P.sub.HRI present in the PSA layer has a mean particle diameter of less than 100 nm and a standard deviation of 20 nm or less. Here, the mean particle diameter and the standard deviation are determined from a number-based particle distribution by TEM analysis.

A method for manufacturing an image display device includes applying a first photo-curable resin composition to a protective panel to form a first photo-curable resin composition layer. The first photo-curable resin composition layer is irradiated with curing light to form a first cured resin layer. A second photo-curable resin composition is applied to the first cured resin layer to form a second photo-curable resin composition layer. The second photo-curable resin composition layer has a reduced or eliminated height difference, compared with the first photo-curable resin composition layer. The protective panel and an image display member are laminated via the second photo-curable resin composition layer. The second photo-curable resin composition layer is irradiated with curing light.
