    • The present invention relates to a process for manufacturing a one-way vision glass pane comprising one or more separate enamel patterns composed of a number of exactly aligned layers, characterized in that:a) at least one protective layer based on oxides, having a thickness greater than or equal to 10 nm, is deposited on the glass substrate, b) at least two layers of different compositions are deposited on the protective layer, the composition of one containing at least one mineral pigment and being free of glass frit, the composition of the other being an enamel containing at least one glass frit and at least one mineral pigment having a color different from that of the layer free of glass frit, the layer free of glass frit being deposited over all or some of the surface of the pane and the layer of enamel being deposited by screen printing in the shape of the desired pattern(s), c) the pane coated with said layers is heated at a temperature sufficient to fire the enamel, and d) the pigments not fixed by the enamel that are located outside of the pattern(s) are removed, the particles of pigment(s) and the particles of glass frit(s) having a similar size, in particular a particle size distribution such that 50% of the particles have a size of less than 7 μm.
    • 本发明涉及一种用于制造提供单向视觉功能的玻璃面板的方法,并且包括由精确重合的多个层组成的一个或多个分立的釉质图案,其特征在于:a)至少一种基于氧化物 在玻璃基板上沉积厚度大于等于10nm的保护层; b)至少两层不同的组合物沉积在保护层上,这些层之一的组合物含有至少一种矿物颜料并且不含玻璃料,另一层的组合物是含有至少一块玻璃料的搪瓷 和至少一种与不含玻璃料的层的颜色不同的矿物颜料,没有玻璃料的层被沉积在面板的所有或一些表面上,并且搪瓷层通过丝网印刷以 所需的图案; c)将涂有所述层的面板加热至足够高的温度以烘烤搪瓷; 和d)不被釉质保持的颜料,即位于图案之外的颜料被去除,颜料颗粒和玻璃料的颗粒具有相似的尺寸,特别是具有 颗粒尺寸分布使得50%的颗粒尺寸小于7μm。
