Abstract

The present invention provides a film for thermal compression bonding, which contains a cholesteric liquid crystal layer that is formed by curing a liquid crystal composition including a polymerizable rod-like liquid crystal compound, a chiral agent, and a polymerizable monomer, in which the polymerizable rod-like liquid crystal includes a monofunctional rod-like liquid crystal compound having one polymerizable group and a bifunctional rod-like liquid crystal compound having two polymerizable groups, or two or more bifunctional rod-like liquid crystal compounds having two polymerizable groups, the polymerizable monomer has three or more polymerizable groups, and the polymerizable monomer is contained in an amount of 0.3% by mass to 6.0% by mass with respect to the total mass of the polymerizable rod-like liquid crystal compounds; a method for producing a molded article using the film for thermal compression bonding; and a molded article produced by the production method.
