Macintosh's company merged with Thomas Hancock's Manchester clothing firm in 1830, and Hancock's 1843 patent for vulcanising rubber solved the early coats' problems of smell and stiffness. Through the 19th and 20th centuries the company kept making waterproof clothing, supplying the British Army, railways and police, before being taken over by Dunlop Rubber in 1925.
Around the turn of the 21st century, senior staff acquired the company and re-established the rubberised Mackintosh coat as an upmarket brand, collaborating with Gucci, Hermès and Louis Vuitton and winning a Queen's Award for Enterprise in 2000. Bought by Tokyo firm Yagi Tsusho in 2007, it launched the fashion-forward Mackintosh 0001 line with Kiko Kostadinov in 2016.
