Abstract
The disclosure relates to a printed film including a base film, a removable printed layer containing an alkali-removable ink, and a finishing varnish layer, the layers being formed on the base film. The finishing varnish layer contains at least a curable resin and a curing agent, and the curing agent is blended in an amount of less than 40 parts by mass based on 100 parts by mass of the curable resin. Thus, the printed layer is prevented from being scratched or peeled off and can be reliably removed by alkali treatment at the time of disposal.
