Abstract

1318706 Diazotype multi-colour processes MITA INDUSTRIAL CO Ltd 31 July 1970 [2 Aug 1969] 37217/70 Addition to 1292163 Heading G2C [Also in Division B6] Multi-coloured azo dye images are produced by exposing to light and heat simultaneously or successively in either order an assembly as set out. In Specification 1292163 except that coupler (b) is present in the diazotype material in an amount of at most 1 mole per mole of the diazomium compound and that coupler (b) is slower than resorcinol as well as being slower than coupler (a) Coupler (a) may be applied to an original as set out in Specification 1292164.
