* Oversubscribed 1.8 times

(Adds detail, comment)

DUBLIN, Nov 5 (Reuters) - Allied Irish Banks (ALBK.I) issued a 750 million euro ($1.1 billion) five-year bond it said was the first unguaranteed issue of its kind with that maturity since a government guarantee for bank liabilities was introduced in September 2008.

The bond, priced at a spread over mid-swaps of 285 basis points, attracted more than 150 international investors and was oversubscribed by 1.8 times, AIB said on Thursday.

"The positive reaction of the international markets by investing in longer-term unsecured and unguaranteed bonds of AIB is a further indicator of the growing positive attitude of the international credit markets towards Irish banks," said Colm Doherty, managing director of AIB Capital Markets.

The bank raised 1 billion euros through a three-year bond in September. (Reporting by Antonella Ciancio; Editing by Andras Gergely and Dan Lalor) ($1 = 0.6734 euro)
