물품 및 라미네이트는 제1 폴리에스테르 표면 및 제2 폴리에스테르 표면을 갖는 기재, 적어도 제1 폴리에스테르 표면 상에 코팅된 가교결합된 폴리우레탄계 프라이머, 및 가교결합된 폴리우레탄계 프라이머에 인접한 광학적으로 투명한 열 활성화 접착제를 포함한다. 물품 및 라미네이트는 적어도 하나의 폴리에스테르 표면 상에 폴리우레탄계 분산물 및 가교결합제를 적용시키는 단계, 적용된 코팅을 건조시키는 단계, 기재와 코팅을 신장하면서 가열하여 신장된 폴리에스테르 표면 상에 가교결합된 프라이머 층을 형성하는 단계 및 가교결합된 프라이머 층 상에 광학적으로 투명한 열 활성화 접착제를 적용하는 단계에 의해 제조된다. Articles and laminates include a substrate with a first polyester surface and a second polyester surface, a crosslinked polyurethane-based primer coated on at least the first polyester surface, and an optically clear heat activated adhesive adjacent to the crosslinked polyurethane-based primer. The articles and laminates are prepared by applying a polyurethane-based dispersion and a crosslinker on at least one polyester surface, drying the applied coating, heating while stretching the substrate and the coating to form a crosslinked primer layer on the stretched polyester surface, and applying an optically clear heat activated adhesive onto the crosslinked primer layer.
