ABSTRACT:
Photographic compounds capable of releasing a photographically useful group are more effective in photographic materials when the photographic compounds comprise at least two differing timing groups in sequence between a carrier moiety and the photographically useful group. The two timing groups in sequence enable improved timing and control of release of the photographically useful group.
