Definitions
- One-step development and stabilization of an exposed photographic silver halide element containing a silver halide developing agent is accomplished by contacting the exposed photographic element with a stabilization bath containing a silver halide stabilizer and polyalkylene glycol maintained at a temperature suflicient to activate the incorporated developer thereby permitting both development of the exposed silver halide in the photographic element and stabilization of the unexposed silver halide.
- the photographic element can be one containing a silver halide developing agent suitable for socalled dry processing with heat, such as set out in British Pat. 930,572 and/or French Pat. 1,463,243.

Defensive Publication applications have not been examined as to the merits of alleged invention. The Patent Oflice makes no assertion as to the novelty of the disclosed sub ect matter.
PUBLISHED OCTOBER 13, 1970 PHOTOGRAPHIC PROCESSING UTILIZING STA- BllLlZlNG BATHS CONTAINING POLYALKYL- ENE GLYCOL Burton D. Wilson, Kodak Park Works, Rochester, N.Y. 14650 Filed Apr. 13, 1970, Ser. No. 28,064 lint. Cl. G03c 5/38 US. Cl. 96-61 No Drawing. 15 Pages Specification Stabilizing baths containing from about 30 to about 80 percent by weight of a polyalkylene glycol, especially polyethylene glycol, having an average molecular Weight of at least about 1,000, a silver halide stabilizer, and a non-aqueous solvent therefor are utilized in the rapid processing of exposed incorporated developer silver halide photographic emulsion coatings to obtain dry, stable prints and negatives with improved keeping properties. One-step development and stabilization of an exposed photographic silver halide element containing a silver halide developing agent is accomplished by contacting the exposed photographic element with a stabilization bath containing a silver halide stabilizer and polyalkylene glycol maintained at a temperature suflicient to activate the incorporated developer thereby permitting both development of the exposed silver halide in the photographic element and stabilization of the unexposed silver halide. The photographic element can be one containing a silver halide developing agent suitable for socalled dry processing with heat, such as set out in British Pat. 930,572 and/or French Pat. 1,463,243.
