| 摘要 |
<p>The invention relates to a coating having a thickness of from 5 to 25 µm, comprising a high-molecular-weight organic material and from 5 to 9 g/m<2> colored pigments, wherein, based on the total amount of colored pigments, (a) from 30 to 90 % by weight of 3,6-di(4'-biphenyl)-2,5-dihydro-pyrrolo[3,4-c]-pyrrole-1,4-dione having a specific surface area of from 20 to 50 m<2>/g and (b) from 10 to 70 % by weight of a further organic colored pigment, selected from the series consisting of quinacridone, diketo-pyrrolo[3,4-c]-pyrrole, dioxazine, indanthrone, perylene, phthalocyanine and 3-amino-1H-isoindol-1-one-oximatometal complex pigments and solid solutions and mixtures thereof, are present.</p> |
