<p>PURPOSE:To obtain reliable and stable operation for a long period by forming an adhesive layer with a mixture of a base polymer of phenoxy resin of high molecular weight with less content of NaCl, special amount of n-butylated melamine resin and stabilized polyisocyanate. CONSTITUTION:100pts.wt. of base polymer of phenoxy resin and/or epoxy resin of high molecular weight having 5ppm or less of NaCl and 0.440 or higher of limit viscosity, 20-50pts.wt. a mixture of n-butylated melamine resin or benzoguanamine resin and stabilized polyisocyalate, and, as required, 0.1-10pts.wt. of 1.8-diazabicyclo(5,4,0)undecene-7 phenol salt as crosslinking density improving agent are used as composition to form an adhesive layer. In this manner, highly reliable and stable operation can be obtained for a long period.</p> |
