Definitions
- This invention relates to dyes and more particularly to dyes formed by coupling during photographic development.
- colored photographic images may be formed by using a developer which forms a colored compound on development.
- the colored compound thus formed is depositedadjacent the silver image during the development.
- a colored image may be formed by adding to the developer solution a compound which combines with the oxidation product of the developer and forms a coloring substance.
- the aromatic amino compounds which may be used as developers in our process include the mono-, di-, and tri-amino aryl compounds and compounds formed therefrom by substitution in the amino group as well as in the ring, such as alkyl phenylene diamines and alkyl toluylene diamines. These compounds are usually used in the salt form, such as the hydrochloride or' the sulphate which are more stable than the amines themselves. Examples are diethylparaphenylene diamine hydrochloride, monomethylparaphenylene diamine hydrochloride, and dimethylparaphenylene diamine sulphate.
- the coupling or color-forming compounds which are used according to our invention are certain compounds containing a substituted acetyl group which includes a reactive methylene group.
- These include acetoacetanilide and substituted acetoacetanilides, such as the halogen and alkylsubstituted compounds. Among these are parabromo acetoacetanilide, dichloro acetoacetanilide, and 4-nitro acetoacetanilide.
- Other compounds containing this group are benzoyl acetone and acetyl acetone.
- acetyl group is substituted with an aceto group, CH3CO-, but it may also be substituted with a cyano, CN, or with any substituent group which will produce a reactive methylene group.
- R an alkyl or an aryl group.
- the group represented by Y must be such that the methylene group to which it is attached is reactive in the dye-forming reaction.
- the acetyl group may contain sulfur instead of oxygen atoms, thus forming thioacetyl groups of the formula s s CHa-- -CH1 l-R Among the color-forming compounds used.
- Our process may be used form colored photographic images in films as well as in plates, and the dyes formed will attach to gelatin or other carrier for the silver halide, such as collodion.
- the emulsion treated may be on one side or on both sides of a film support and may be in one layer or a plurality of differently sensitized layers.
- the dyes formed may be bleached by an oxidizing agent, such as chromic acid, and colorless soluble compounds thereby formed. The bleaching of the dye in this manner does not destroy the silver image and a silver image may be colored, bleached, and recolored a number of times.
- an oxidizing agent such as chromic acid
- a color-forming photographic developer comprising an aromatic amino developing compound and a coupler compound having the termula where R is a group selected from the group consistlng of alkyl and aryl groups.
- a color-forming photographic developer comprising an aromatic amino developing compound and acetyl acetone.
- a color-forming photographic developer comprising an aromatic amino developing comp und and benzoyl acetone.
- a color-forming photographic developer comprising a paraphenylenediamine developing compound and a coupler compound having the formula II II where R is a group selected from the group consisting of alkyl and aryl groups.
