Claim 16:
17. A method for producing a transdermal therapeutic system according to claim 1, wherein the method comprises the following steps
providing a first carrier layer or producing a starting laminate comprising a first carrier layer,
applying a flowable active-substance-containing composition, comprising nicotine as active substance, wherein the nicotine is in the form of a free base, and at least one polymer with at least one acid amide group as a lateral functional group, wherein the polymer with at least one acid amide group as a lateral functional group is a vinylpyrrolidone-vinyl acetate copolymer to the first carrier layer or the starting laminate, and
laminating the rest of the layers of the transdermal therapeutic system, comprising a second carrier layer, onto the first carrier layer provided with the active-substance-containing composition or the starting laminate provided with the active-substance-containing composition,, wherein the transdermal therapeutic systems can be separated by being cut and/or punched from the product or laminate created up to that point, before or after the application of the active-substance-containing composition, and the first carrier layer forms the detachable protective layer, which is impermeable to nicotine, and the second carrier layer forms the back layer impermeable to nicotine, or vice versa.
