Patent ID: 7105601

Claim:
An adhesive resin composition comprising, based on the total weight of the composition: about 5 to about 95 weight percent of a first resin component comprising a first resin having a first glass transition temperature of about −15° C. to about 10° C., and a second resin having a second glass transition temperature of about 10° C. to about 50° C., wherein the first glass transition temperature is different from the second glass transition temperature; about 5 to about 49 weight percent of a second resin component having one or more glass transition temperatures greater than about 100° C., wherein the second resin component comprises phenolic resin, acrylic resin, polyphenylene ether resin, or a combination comprising at least one of the forgoing resins; and up to about 50 weight percent of a particulate inorganic filler; wherein a tan δ value of the adhesive resin composition is greater than about 0.2 over a temperature range of about −15° C. to about 50° C. when measured at a frequency of 1 Hz.
