    • A patterned decorative material is prepared by a method which comprises applying a thermosetting powder coating material to a base plate; melting of the thermosetting powder coating material by heating; simultaneously embossing the coating layer and the base plate while the melted thermosetting powder coating material has a gel fraction formed by a hardening reaction of 0 to 75 weight percent; and further heating to form a hardened coating on the base plate. The patterned decorative material is excellent in appearance, corrosion resistance, weathering resistance and abrasion resistance and is free from the defects of conventional steel plates coated with polyvinyl chloride and the like, such as formation of craze and loss of luster.
    • 图案化装饰材料通过包括将热固性粉末涂料施加于基板的方法制备; 通过加热熔化热固性粉末涂料; 同时对涂层和基板进行压花,同时熔化的热固性粉末涂料具有通过0至75重量%的硬化反应形成的凝胶分数; 并进一步加热以在基板上形成硬化涂层。 图案化的装饰材料的外观,耐腐蚀性,耐候性和耐磨性优异,并且不存在涂覆有聚氯乙烯等的常规钢板的缺陷,例如形成热潮和失光。
