PROBLEM TO BE SOLVED: To provide a heat ray reflection film excellent in adhesiveness between a cholesteric liquid crystal polymer layer and a transparent base material without using a primer, and excellent in visibility with few interference bands.SOLUTION: A heat ray reflection film 10 includes: a cholesteric liquid crystal polymer layer 12; and a transparent base material 11. The cholesteric liquid crystal polymer layer 12 is formed by photopolymerization of at least two kinds of liquid crystal compounds each with a polymerizable functional group, a chiral agent having a polymerizable functional group, a polyfunctional acrylate compound, and a polyfunctional thiol compound. The content of the polyfunctional acrylate compound is at most 5 pts.mass to 100 pts.mass of the total of the at least two kinds of liquid crystal compounds and the chiral agent, and the content of the polyfunctional thiol compound is at least 5 pts.mass to 100 pts.mass of the total of the at least two kinds of liquid crystal compounds and the chiral agent. |
