HEAT STORAGE MATERIAL COMPOSITION

A heat storage material composition obtained by thermally treating component (A) which is a polyhydric alcohol free from any structural unit derived from a vinyl monomer and the following polymers (B 1) and (B 2) said heat storage material composition having excellent shape retainability and high bleeding resistance. Polymer (B 1): a polymer comprising as a main component a structural unit derived from acrylic acid or a salt thereof a polymer comprising as a main component a structural unit derived from methacrylic acid or a salt thereof or a mixture of these polymers (excluding a polymer having two or more hydroxyl groups attached to a single polymer chain). Polymer (B 2): A polymer having two or more hydroxyl groups attached to a single polymer chain and comprising as a main component a structural unit derived from a vinyl monomer.
