Following a raised cash and shares takeover proposal from PPG for Akzo worth about 26.9 billion euros (22.5 billion pounds) or 96.75 euros per share, Columbia said the company's boards should drop their resistance.

"Akzo Nobel have no more room for excuses now and must enter into proper discussions with PPG," a spokesman for Columbia said.

Akzo, which has quickly rejected proposals from PPG on two previous occasions, said on Monday it would "carefully review and consider" the latest proposal, which also offered employment guarantees and a break fee.
