eliminating bleaching and fixing steps (reply brief, pages 8-
9).
The examiner argues that because the combined teachings
of Hara, Schenk, Peters and Cole show that either color or
black and white dye transfer images may be formed by diffusion
transfer processes, including both wet processes and heat
development of silver halide elements to form transferable
dyes, and Hara discloses the advantage of using heat transfer
of dyes to form black and white images free of residual silver
or silver halide, it would have been obvious to one of
ordinary skill in the art to use balanced mixtures of heat
diffusible dye forming compounds of Texter for forming black
and white transfer images not containing silver or silver
halide (answer, pages 5 and 8). The examiner argues that
