A transparent roof panel assembly for a vehicle roof comprises a panel (100) and a light source (104) arranged to provide light in the panel. The panel includes a first transparent layer (102) having a first major surface and a second major surface opposite the first major surface, a second transparent layer (103) disposed adjacent to the first major surface, and a light outcoupling pattern (106) disposed between the first major surface of the first transparent layer and the second transparent layer. The light outcoupling pattern is configured for scattering at least a portion of light (105) from the light source such that at least a portion of the light exits the first transparent layer through the second major surface. The light outcoupling pattern includes scattering particles disposed in a transparent carrier composition. The scattering particles are pigments (110) in a white ink having a pigment concentration of 0.01 wt% to 1.5 wt%. The light out-coupling pattern may form an image created by dots of a transparent carrier composition (109) comprising a pigment (110). The image has a contour formed by a full-surface printed contour line having a width similar to a representative point diameter of a point forming the image.

    一种用于车辆车顶的透明车顶面板组件包括面板(100)和被布置成在所述面板中提供光的光源(104)。所述面板包括具有第一主表面和与所述第一主表面相对的第二主表面的第一透明层(102)、邻近于所述第一主表面布置的第二透明层(103)以及布置于所述第一透明层的第一主表面与所述第二透明层之间的光输出耦合图案(106)。所述光输出耦合图案被构造成用于散射来自所述光源的光(105)的至少一部分,以使得所述光的至少一部分通过所述第二主表面离开所述第一透明层。所述光输出耦合图案包括布置于透明载体组合物中的散射颗粒。所述散射颗粒为具有0.01重量%‑1.5重量%的颜料浓度的白色油墨中的颜料(110)。所述光输出耦合图案可以形成由包括颜料(110)的透明载体组合物(109)的点创建的图像。所述图像具有由全表面打印轮廓线形成的轮廓,所述全表面打印轮廓线的宽度与形成所述图像的点的代表性点直径相似。
