Abstract: A composite phase change material, including 65 to 80 parts of a phase change material and 20 to 35 parts of a binder by weight. The binder includes an acrylate monomer having a molecular weight of 50 to 300, an acrylate polymer having a molecular weight of 500 to 2000, and an initiator. The initiator in the composite phase change material can generate free radicals under the condition of ultraviolet light irradiation to initiate polymerization reactions between components of the composite phase change material, so that the composite phase change material is cured, thereby greatly accelerating a cure speed of the composite phase change material.

Abstract: An object lies in providing a novel water-absorbing resin and a novel absorbent body both of which enable provision of an absorbent article that prevents swelling of a water-absorbing portion when used in a thin absorbent article. The object is achieved by providing a water-absorbing resin that is a particulate poly(meth)acrylic acid (salt)-based water-absorbing resin and has a swollen gel compressibility rate of 3% or more expressed by Formula 1: Swollen gel compressibility rate [%]=(D1−D2)/D1×100 (Formula 1), where D1 represents a thickness of a swollen gel before compression, and D2 represents a thickness of a swollen gel after compression.
