Polymers containing resorcinol groups and photographic elements containing same

Claim 2

A photographic element according to claim 1 wherein said photographic element comprises from about 5 mg. to about 100 mg. per square foot of said polymer.

Claim 3

A photographic element according to claim 1 wherein said photographic element comprises at least one layer containing a silver halide emulsion.

Claim 4

A photographic element according to claim 1 wherein said photographic element comprises at least one layer containing a photographic color-forming coupler.

Claim 5

A photographic element according to claim 1 wherein said polymer comprises units represented by the formula:

Claim 6

A photographic element according to claim 1 wherein said polymer is a water-soluble polymer or a latex polymer.

Claim 7

A photographic element according to claim 6 wherein said polymer is a copolymer comprising units represented by the formula in copolymerized relationship with units of at least one other ethylenically unsaturated monomer.

Claim 8

A photographic element according to claim 1 which comprises at least one layer containing a silver halide emulsion having associated therewith a photographic color coupler.

Claim 9

In a photographic film unit which is adapted to be processed by passing said unit between a pair of juxtaposed pressure-applying members comprising: a. a photosensitive element comprising a support having thereon at least one photosensitive silver halide emulsion layer, each said silver halide emulsion layer having associated therewith a nondiffusible coupler capable of reacting with oxidized aromatic primary amino color-developing agent to produce a diffusible dye; b. a dye image-receiving layer; and c. a rupturable container containing an alkaline processing composition and which is adapted to be positioned during processing of said film unit so that a compressive force applied to said container by said pressure-applying members will effect a discharge of the container''s contents within said film unit; said film unit containing an aromatic primary amino color-developing agent, the improvement comprising employing in said element a developing agent scavenger comprising a polymer having resorcinol groups appended thereto.

Claim 10

The film unit of claim 10 wherein said dye imagereceiving layer is located on a separate support to be superposed on said photosensitive element and said developing agent scavenger is located between said support and said image-receiving layer.

Claim 11

The film unit of claim 10 which contains a timing layer between said scavenger layer and said dye image-receiving layer.

Claim 12

The film unit of claim 10 which also contains a pH-lowering material.

Claim 13

The film unit according to claim 10 wherein said polymer comprises ethenic units having resorcinol groups appended thereto and units of at least one other ethylenically unsaturated monomer having water-solubilizing groups thereon.

Claim 14

In a process of forming a transfer image comprising: a imagewise-exposing a photosensitive element comprising a support having thereon at least one photosensitive silver halide emulsion layer, each said silver halide emulsion layer having associated therewith a nondiffusible coupler capable of reacting with oxidized aromatic primary amino color-developing agent to produce a diffusible dye; b treating the layer outermost from the support of said photosensitive element with an alkaline processing composition to effect development of each of said exposed silver halide emulsion layers with an aromatic primary amino color-developing agent; c forming an imagewise distribution of diffusible dye image-providing material as a function of said imagewise exposure of each said silver halide emulsion layer; and d at least a portion of each said imagewise distribution of diffusible dye image-providing material diffusing to a dye image-receiving layer; the improvement comprising employing in said film unit a developing agent scavenger layer comprising a polymer having resorcinol groups appended thereto.
