- the invention relates to a transfer film, a method for producing a transfer film and a component and a method for producing it using a transfer film.
- IMD In Mold Decoration
- the IMD transfer films often have protective layers which, after a carrier layer of the IMD transfer film has been detached, form an outer side of the products.
- the protective layers have a low level of adhesion for foreign matter.
- the protective layers also have poor adhesion for materials applied to them, such as printing inks, for example, so that the protective layers cannot be overprinted. Printing inks are therefore arranged on the inside of the protective layers, i.e. the protected side.
- Films with a higher adhesion for printing inks are only known for fast-moving goods, such as packaging, and have no protective varnish or are poorly resistant.
- a transfer film in particular for decorating trim components for motor vehicles or household appliances, which comprises a carrier layer with at least one carrier layer and a transfer layer arranged on the carrier layer.
- the transfer film is characterized in that the transfer layer has a protective layer composite comprising a first protective layer and at least one acceptance layer for coating the transfer layer in a coatable area with at least one coating, the at least one acceptance layer being arranged on the first protective layer and the at least one Acceptance layer is arranged on a first surface of the transfer layer facing the carrier layer.
- the object is further achieved by providing a method for producing a transfer film, in particular according to one of Claims 1 to 23, the following steps being carried out, in particular in the specified order: I) providing at least one carrier layer of a carrier layer; III) applying a transfer layer to the carrier layer, the transfer layer having a protective layer composite comprising a first protective layer and at least one acceptance layer for coating the transfer layer in a coatable area with at least one coating, the at least one acceptance layer being arranged on the first protective layer and the at least one acceptance layer is arranged on a first surface of the transfer layer facing the carrier layer.
