PROBLEM TO BE SOLVED: To provide a manufacturing method for a foldable hard coating film that includes a step of making a composition for forming a hard coating layer partially unhardened upon primarily hardening, and then hardening the whole upon secondary hardening.SOLUTION: A manufacturing method for a foldable hard coating film includes a process for performing a step of coating a substrate film 1 with a composition 11 for forming a hard coating layer, a step of selectively primarily hardening an unfolding part region 103, and a step of secondarily hardening the whole of a film. Preferably, the manufacturing method for the foldable hard coating film includes heat treatment between the primary hardening and the secondary hardening. The manufacturing method for the foldable hard coating film makes a folding part 101 join to the unfolding part region 103 by gentle inclination to satisfy formula (1) between a thickness (Ta) of the folding part 101 and a thickness (Tb) of the unfolding part 103. 0.5≤Ta/Tb×100≤70...(1)SELECTED DRAWING: Figure 1 |
