    • PROBLEM TO BE SOLVED: To provide a resin composition for cleaning for a resin molding processing machine, the resin composition facilitating determination of the end of removal treatment and capable of reducing an amount of the resin used for removing the cleaning agent or a defect due to the remaining cleaning agent when the resin molding processing machine is cleaned with the cleaning agent and the cleaning agent is extruded and removed with the resin to be used next, and to provide a method of cleaning the resin molding processing machine. SOLUTION: A fluorescence-generating tracer substance is added to a thermoplastic resin to produce the cleaning resin composition for the resin molding processing machine. After the resin molding processing machine is cleaned with the cleaning resin composition, the cleaning resin composition remaining in the resin molding processing machine after cleaning is excluded with the molding resin to be used next. The presence or absence of the remaining cleaning resin composition is determined by the recognition of the presence or absence of the fluorescence on the surface of the molding.

    • 解决问题的方案为了提供一种用于树脂成型加工机的清洗用树脂组合物,该树脂组合物有助于确定去除处理结束并能够减少用于除去清洁剂的树脂的量或 在用清洗剂清洗树脂成型加工机时,由于残留的清洗剂而导致的缺陷,并且用接下来要使用的树脂挤出除去清洗剂,并提供清洗树脂成型加工机的方法。 解决方案:向热塑性树脂中加入产生荧光的示踪剂物质,以制备用于树脂模塑加工机的清洁树脂组合物。 在树脂成形加工机用清洗树脂组合物清洗之后,用下一次使用的成型树脂除去残留在树脂成型加工机中的清洗后的清洗树脂组合物。 剩余的清洁树脂组合物的存在或不存在通过识别模制品表面上荧光的存在或不存在来确定。 版权所有(C)2010,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a resin structure body capable of white marking which can mark good without decreasing a design of a coloring part due to stain, wear or the like after marking and is excellent in a visibility. SOLUTION: A resin structure is composed of a resin molding composed of at least one kind of thermoplastic resin selected from olefin rein, styrene series resin, acrylic resin and polyamide resin which can color white by forming a foaming structure due to irradiation with laser beams, and single or multiple protective layers formed adhering to a surface to the resin molding. Total light transmittance of a protective layer is 35-100%, and a layer adjoining at least the resin molding among the protective layers is the resin structured body capable of being white marked which is composed of a resin of 30% or over in tensile elongation in ISO 527 (50 mm/min in tensile speed).
