摘要：PURPOSE:To prepare a film low in specular gloss, excellent in adhesive properties and printability, using an aromatic polyamide of straight configuration excellent in heat resistance and mechanical properties. CONSTITUTION:The objective film consisting of an aromatic polyamide of straight configuration >= 3.5 in logarithmic viscosity, has the following characteristics: (1) omnidirectional Young' s modulus: >= 800 kh/mm<2>, (2) omnidirectional tensile elongation: >= 10%, and (3) surface specular gloss (Gs (60 deg.C)): <=20 %. In producing this film, a wet film after washing with water is subjected to pressure contact with a sattin-finished surface followed by drying the film under restricting its shrinkage; or, the original film is sprayed with sand 0.05-0.7 mm in the maximum particle diameter.
