    • The present invention is to provide a new surfactant that can be used as an emulsifier excellent in emulsion stability and texture in use and as a cleanser excellent in cleansing power and texture in use and having low skin irritation. A surfactant consisting of a compound represented by the below-described general formula (1). Y—O-(EO)l-(AO)m-(EO)n-X  (1) (In the formula, AO represents an oxyalkylene group having 3 to 4 carbon atoms; m is the average addition mole number of the oxyalkylene group and satisfies 5≦m≦100. EO represents an oxyethylene group; l and n are the average addition mole numbers of the oxyethylene groups and satisfy 0≦l≦4 and 0≦n≦4. Either X or Y or both are a functional group represented by —SO3M, —COOM, —HPO3M, —(CH2)q—SO3M, or —(CH2)q—COO, wherein M is a hydrogen ion or a monovalent inorganic or organic cation, and q is the number of carbon atoms of the linked alkylene group and satisfies 1≦q≦4. When either X or Y is the above-described functional group, the other one can be a hydrogen atom, a methyl group, or an ethyl group.)

    • This invention relates to laminates for use in HDD suspensions which are composed of a stainless steel base material and successive layers formed thereon of polyimides and an electrical conductor and in which the linear expansion coefficient of the polyimide layer is controlled in the range of 1×10−5/° C. to 3×10−5/° C. and the adhesive strength between stainless steel and polyimide and that between polyimide and electrical conductor are controlled at 0.5 kg/cm or more. This invention also relates to a process for preparing laminates for use in HDD suspensions comprising applying a solution of polyimide precursors or polyimides to a stainless steel base material with a thickness of 10 to 70 &mgr;m in one layer or more, drying, performing heat treatment at 250° C. or more to form a layer of polyimides with a thickness of 3 to 20 &mgr;m and a linear expansion coefficient of 1×10−5/° C. to 3×10−5/° C. and contact-bonding said layer of polyimides under heat to a layer of electrical conductor with a thickness of 3 to 20 &mgr;m. Laminates of this invention for use in HDD suspensions are practically free of deflection during etching and are suited for integrally-wired HDD suspensions.
    • 本发明涉及用于HDD悬浮液的层压板,其由不锈钢基材和其上形成的连续层组成聚酰亚胺和电导体,其中聚酰亚胺层的线膨胀系数控制在1×10-5 /℃至3×10-5 /℃,不锈钢和聚酰亚胺之间的粘合强度以及聚酰亚胺和电导体之间的粘合强度控制在0.5kg / cm以上。 本发明还涉及一种制备用于HDD悬浮液的层压板的方法,包括将聚酰亚胺前体或聚酰亚胺溶液涂覆在一层或多层中具有10-70μm厚度的不锈钢基材,干燥,进行热处理 250℃或更高以形成厚度为3至20μm的线性膨胀系数为1×10 -5 /℃至3×10 -5 /℃的聚酰亚胺层,并将所述聚酰亚胺层接触粘合在 加热到厚度为3至20微米的电导体层。用于HDD悬架的本发明的层压板在蚀刻期间实际上不会发生偏转,并且适用于整体连接的HDD悬架。
