Appeal No. 94-3359 Application 07/941,566 of a hydroquinone derivative (column 1, line 65 through column 2, line 2). The particle size of the solid particles range from 0.01 microns to about 10 microns (column 8, lines 39 through 42). The photographic elements may be black-and-white or color column 9, line 7 through column 11, line 10). IBM discloses photographic elements comprising a support having at least one silver halide emulsion layer coated thereon and which further contains a novolak resin therein (page 2, lines 9 through 30). The resin is prepared by the reaction of hydroquinone with formaldehyde (page 2, lines 21 through 25). Preferred molecular weights for the novolak resin are from 300 to 600 but greater or lesser molecular weights may be used (page 2, lines 53 through 57). The novolak resins act as non-diffusing developers and image strengtheners (page 2, lines 58 through 61). Novolak resins having greater molecular weights tend not to diffuse in the silver halide gelatin emulsion which is an especially desirable property (page 3, lines 65 through 78). Novolak resins prepared from catechol are comparable in performance to the hydroquinone novolak resins (page 3, lines 93 through 106).
