Document Type and Number:
WIPO Patent Application WO/2005/078035
Kind Code:
A1
Abstract:
An adhesive agent which comprises a polyester based hot melt resin which has crystallinity, exhibits a loss tangent (tan &dgr ) in the temperature dispersion curve by the dynamic visco-elasticity measurement of 4.9 X 10-2 or more in the range of -40°C to 40°C, has a maximum peak value of said loss tangent (tan &dgr ) in the range of -15°C to 40°C and a melting point (Tm) of 95°C to 130°C, or a hot melt resin composition comprising said resin; and a coating film for an electric material having an adhesive layer formed by the use of the adhesive agent. The adhesive agent exhibits excellent adhesive performance capability over a wide temperature range from a low temperature to a high temperature, and the coating film for an electric material exhibits high durability and high handling characteristics.
