发明名称 IMAGED ANTI-COPY FILM
摘要 <p>An anti-copy film is disclosed. The film has a light transmissive imageable substrate having opposing first and second surfaces. Each surface has an image receptive coating. Complementary positive and negative images are disposed on the first and second surfaces such that an imaged area on the first surface is in registration with a non-imaged area on the second surface. The anti-copy film appears substantially opaque when viewed orthogonally to and appears partially transparent when viewed obliquely to either the first or second surfaces.</p>
