| abstract | The invention provides a laminate comprising a transparent resin film based on a polyimide polymer, which is less likely to cause whitening on the film surface and has good appearance and visibility. The laminate comprises a transparent resin film and a protective film bonded to at least one surface of the transparent resin film, wherein the transparent resin film comprises at least 1 and 1 or more solvents selected from the group consisting of polyimide, polyamide and polyamideimide, and is produced by a casting method using the 1 or more solvents, wherein the solvent having the highest boiling point among the 1 or more solvents has a boiling point of 120 to 300 ℃, the residual solvent amount S (mass%) of the transparent resin film and the low molecular weight component W (%) of the protective film satisfy the relational expression (1), W is 0.33 or less, the residual solvent amount S is calculated as the mass reduction rate from 120 ℃ to 250 ℃ based on thermogravimetric-differential thermal measurement, and the low molecular weight component W is defined as the ratio of the Log M in a graph measured at a measurement temperature of 140 ℃ by gel permeation chromatography to the total area, wherein the Log M is 2.82 to 3.32. S multiplied by W is less than or equal to 4.7 (1). |
