- Synthesis of the condensate of the halogenated polyhydroxybenzene and formalin can be carried out according to the concentional synthesis method for a phenolformaldehyde resin of the novolak type.
- the general synthesis method is as follows: The halogenated polyhydroxybenzene is dissolved or dispersed in water, to which a mineral acid, such as concentrated hydrochloric acid or sulfuric acid, and 37% formalin (aqueous solution of formaldehyde) are added, and the mixture is heated at C. for from 30 minutes to 1 hour with agitation. The reaction can be carried out under a pressure in an autoclave. After the reaction, the product is poured in cold water and the resultant precipitate is purified.
- a mineral acid such as concentrated hydrochloric acid or sulfuric acid
- formalin aqueous solution of formaldehyde
- Another example is as follows: 400 parts of o-chlorophenol is dispersed in 1,000 parts of water with vigorous agitation, to which 25 parts of 35% hydrochloric acid and 250 parts of 37% formalin are then added. Then, the reaction mixture is heated at 100 C. with stirring and held for 30 minutes. 20 parts of concentrated hydrochloric acid is added additionally and the reaction is further continued for another 30 minutes. 20 parts of concentrated hydrochloric acid is then added and stirred to give a white turbidity. After about 1 hour and 30 minutes, the stirring is stopped and the mixture is transferred into 3,000 parts of cold water with agitation. The resulting precipitate is filtered, not dried, re-dissolved in 500 parts of methanol and precipitated again with cold water. Then, the precipitate is filtered and dried to obtain the desired product.

- Addition of the sensitizing dye can be carried out using methods known to those skilled in the art.
- the formalin condensate can be added to a silver halide emulsion in the form of a solution in an organic solvent such as methanol or ethanol.
- the sensitizing dye and formalin condensate are preferably added to an emulsion before the application of the emulsion.
- the order of addition to the emulsion is not limited particularly. Any of the sensitizing dyes and the formalin condensate can be added firstly or the both can be added in admixture. Furthermore, they can be added to an emulsion after water washing and during ageing.
