Vivex process, the only process to become commercially available for producing full-colour carbro prints. The Vivex company was founded c.1930 by D. A. Spencer, who had patented a number of modifications to the process, including a simplified chemical procedure, and the temporary support of the cyan, magenta, and yellow images on cellophane, the flexibility of which simplified the registration of portraits made with three successive exposures using the cumbersome repeating-back system. Vivex later marketed a one-shot camera using dichroic beamsplitters, and colour portraitists such as Mme Yevonde used this with great success until the company's Willesden processing plant closed on the outbreak of the Second World War. In Madame Yevonde: Colour, Fantasy and Myth (1990), Pam Roberts describes both the complexities of the original process and the creation of modern dye transfer prints from Yevonde's negatives.
