摘要： The present invention provides a method for manufacturing recording paper, in which a transfer film (4), on which a pigment-containing surface layer (3) that adheres to the absorption layer (2) has been spread, is placed on an absorption layer (2) that has been formed on a substrate (1). Thereafter the transfer film (4) is detached so that the surface layer (3) remains on the absorption layer (2). The material of the absorption layer (2) is spread in a molten state due to extrusion on the substrate (1), and the transfer film (4) is placed with its surface layer (3) against the absorption layer (2) in such a way that the surface layer comes into contact with the material of the absorption layer (2) while it, as a result of extrusion, is still at a temperature that promotes adhesion. After the material of the absorption layer has cooled down, the transfer film (4) is detached from the absorption layer (2) to reveal that surface of the surface layer (3) that as been against the surface of the transfer film (4). The amount of pigment in the surface layer may be from 50-80% by weight.
摘要翻译：本发明提供了一种制造记录纸的方法，其中在其上铺展粘附有吸收层（2）的含颜料的表面层（3）的转印膜（4）放置在吸收层（2），其形成在基板（1）上。此后，转移膜（4）被分离，使得表面层（3）保留在吸收层（2）上。吸收层（2）的材料由于在基板（1）上的挤出而在熔融状态下扩散，并且转印膜（4）以其表面层（3）放置在吸收层（2）上表面层与吸收层（2）的材料接触的方式，而作为挤出的结果，其仍处于促进粘附的温度。在吸收层的材料已经冷却之后，转印膜（4）从吸收层（2）分离，以揭示表面层（3）的与转印膜（4）表面相反的表面，。表层中颜料的量可以为50-80重量％。

摘要： The invention relates to the manufacture of an output or printing base, preferably intended for ink-jet printing and comprising a base layer and a printing layer which is of a pigmented polymer. The printing layer is a film which has been oriented mono- or biaxially in such a way that the bonds between said pigments and the polymer material of the film have been, at least to a significant degree on at least some edge of the pigment particle, released and form slits in the order of a micrometer or a nanometer on the surface which absorbs, primarily or secondarily, ink and/or its solvent during printing.
摘要翻译：本发明涉及一种输出或印刷基底的制造，优选用于喷墨印刷，并且包括基底层和作为着色聚合物的印刷层。印刷层是已经以单轴或双轴取向的方式使得所述颜料和膜的聚合物材料之间的键至少在颜料颗粒的至少一些边缘处至少显着的程度，释放并在表面上以微米级或纳米级的顺序形成狭缝，其在印刷过程中主要或次要地吸收油墨和/或其溶剂。

摘要： A printing paper, especially for ink-jet printing, comprises a carrier (1) and a hydrophilic absorption layer (2) spread by the extrusion coating technique on top of the carrier (1) and a pigment-containing top-coating layer (3) on top of the above-mentioned absorption layer. The top-coating layer (3) contains as the pigment at least 40 wt % of colloidal silica, preferably between 40 and 80 wt %.
