Abstract
Abstract There is disclosed a dry thermal transfer decal consisting of a single polyamide film having decoration thereon which film serves as a carrier for the decoration, a protective coating for the decoration and the adhesive layer. The polyamide is the thermal amidification product of essentially equivalent amounts of a polymeric fat acid having a dimeric fat acid content greater than 80 percent by weight and of a diprimary diamine.
