摘要：
An object of the invention is to provide an adhesive for a polarizing plate that has high adhering strength, makes it possible to prevent a reduction in the light transmittance of a polarizing plate and to suppress the occurrence of knicks, and is less likely to cause a reduction in the light transmittance of a polarizing plate even in a humidified environment while having the above characteristics. The invention is directed to an adhesive for a polarizing plate for use in fixing a transparent protective film on at least one side of a polarizer, the adhesive including a resin solution containing a polyvinyl alcohol-based resin and a water-soluble silicate.
