Definitions
- Our present invention relates to the manufac opment (chromogenic development) color pictures can be obtained photographically as described, for instance, in.U. S. Patent No. 1,102,028.
- amines for example, amines, phenols, aminophenols, 1 naphthols, aminonaphthols and bodies with the ticularly if the solubility in water is not suilicient.
- layers containing these bodies are suitable for formingthe required multi-layer material, since diffusion from one layer to another cannot occur.
- Suitable highly polymeric carboxylic acids and substances like polyglycuronic acids, prote'inaminc acids or synthetic compounds from unsaturated organic acids such as polyvinylcarboxylic acids (polyacrylic acid alone or as a mixed polymerizate with styrene, vinylchlorida'vinylether or nitrogeneous vinyl compounds such as vinylcarbazole or the like), polymerizates of maleic acid, fumaric acid, methylene-malonic acid, alone A or as mixed polymerizates with vinyl compounds.
- polycarboxylic acids are caused to react in the form of their acid chlorides or anhydrides or esters or other reactive derivatives with the aforesaid reactive amines, phenols and bodies with active methylene groups, for example with aminophenols, phenylenediamines, aminonaphthols,
- aminoacetic acid anhydrides aminobenzoylaceticacid esters, aminophenylmethylpyrazolones, hydroxynaphthoic acid aminoarylides, diazo-bodies, leuco-dyestuffs, or the like,
- Example 1 --l gram of a condensation product from metaaminophenylmethylpyrazolone and the mixed polymerizate from vinylchloride and maleic acid anhydride' are ground with 5 cc.,.oi caustic soda lye of 5 per centstrength and then dissolved in water. The solution is added to 100 cc. of silver bromide emulsion. A layer of this emulsion may be developed with para-amlnodimethylaniline to a picture which consists of a red dyestufl after the separation of the silver.
- Example-1 but instead of a pyrazolone and a condensation productv there is used. one made from 1.-5.-aminonaphthol and the mixed polymerizate namedin Example 1; the layer made yields a picture in a blue dyestufl.
- carboxylic acid derivative consisting of a carbon chain molecule wherein the color forming group recurs periodically in pairs, each group of a pair beingpnnited by an acid amide linkage to adjacent carbon atoms of said chain.
