    • PURPOSE:To obtain fine and sharp multi-color decorative sheet by a method wherein liquid coloring material layers having a plurality of colors are formed successively onto a releasable base material and then sheet-like designed material obtained by removing the releasable base material from the layers is granulated and the resultant granule aggregate is hot-rolled. CONSTITUTION:Liquid coloring material layers are successively formed by coloring material layer forming devices 2, 5, 8 and 11 onto the releasable base material 1 utilizing thermoplastic resin as binders and, after each formation of layer, the respective layers are dried in ovens 3, 6, 9 and 12 respectively. After drying, sheet-like designed materials are obtained by being cooled on cooling rolls 4, 7, 10 and 13 respectively. Then the sheet-like designed material 14 obtained by removing the releasable base material 1 is crushed in succession at a grinder 15 in order to obtain the granule 16 of designed material. Next, the granule aggregate is heat-rolled by a calender roll in order to obtain the multi-color decorative sheet. The sheet-like designed material 14 consists of the coloring material layers (a), (b), (c) and (d) having four different colors.
    • 目的:通过将具有多种颜色的液体着色材料层依次形成在可剥离基材上的方法获得精细且锐利的多色装饰片,然后通过从层中除去可剥离的基材而获得的片状设计材料 造粒,得到的颗粒聚集体被热轧。 构成:利用热塑性树脂作为粘合剂,将着色材料层形成装置2,5,8和11依次形成液体着色材料层到可剥离的基材1上,并且每层形成后,各层在烘箱3中干燥, 分别为6,9和12。 干燥后,分别通过在冷却辊4,7,10和13上冷却来获得片状设计的材料。 然后,通过除去可剥离基材1而获得的片状设计材料14在研磨机15上连续粉碎,以获得设计材料的颗粒16。 接下来,通过压延辊将颗粒聚集体热轧,以获得多色装饰片。 片状设计材料14由具有四种不同颜色的着色材料层(a),(b),(c)和(d)组成。
