Method for producing adhesive layer composition for producing cooling sheet, method for producing cooling sheet, and cooling sheet

Abstract

A method for producing an adhesive layer composition for producing a cooling sheet including a backing layer, an adhesive layer, and a liner layer, the method comprising the step of: mixing a composition to be mixed containing water, an alum, sodium edetate, a polyacrylic acid, and a neutralized polyacrylic acid such that a mixing temperature becomes 5 to 23° C., to obtain an adhesive layer composition, wherein in the composition to be mixed, a content of the water is 69 to 938.24% by mass relative to a total mass of the composition to be mixed, a content of the alum is 0.18 to 0.42% by mass relative to the total mass of the composition to be mixed, a content of the sodium edetate is 0.08 to 0.18% by mass relative to the total mass of the composition to be mixed, and a mass ratio between the content of the alum and the content of the sodium edetate (the content of the alum: the content of the sodium edetate) is 1:1 to 5.25:1.
