Narrative:

Departing sea and climbing through 26000 ft, we got the 'tail compartment temperature high' light on. Ran qrc and QRH checklist. Light did not go out in checklist specified time period and so diverted to pdx, as directed by checklist. We declared an emergency. ATC did a nice job of getting us on the ground. We were vectored for an ILS runway 28L and landed uneventfully. An overweight landing was necessary and was written up in logbook.
