Abstract
The Specification refers to sulphur-containing hydroxy acid of formula: HO-R2-S-R10-COOH where R2 is an alkylene group containing 2-20 carbon atoms and R10 is an alkylene group containing 1-10 carbon atoms, and to the lactones of these hydroxy acids. In Example (4) Hydroxylpropylmercaptopropionic lactone was prepared by heating gamma-mercapto propanol with acrylic acid in the presence of hydroquinone; (5) Hydroxyhexylmercaptopropionic acid lactone was similarly prepared from omega-mercapto hexanol; (7) gammahydroxypropylmercaptoacetic acid lactone was prepared by heating mercaptoacetic acid with gamma-chloropropanol in the presence of aqueous sodium hydroxide, extracting the resulting solid with acetone and then suspending it in ethanol and hydrochloric acid to obtain a salt which was washed with alcohol and distilled.ALSO:Polymers for increasing the sensitivity of photographic silver halide emulsions have at least three recurring units of the formula: -R10-COO-R2-S-where R2 is an alkylene group containing 2-20 carbon atoms and R10 is an alkylene group containing 1-20 carbon atoms The polymers may have a molecular weight of 500-10,000 and are made by the auto-condensation of a hydroxyacid of formula: HO-R2-S-R10-COOH or its corresponding lactone. The latter condensation may be effected in the presence of p-toluene sulphonic acid, chloracetic acid or zinc chloride. Examples describe the polymerization of (1)-(3) Hydroxyethylmercaptoacetic acid lactone; (4) Hydroxypropylmercaptopropionic acid lactone; (5) Hydroxyethylmercaptopropionic acid lactone; (6) Hydroxyhexylmercaptopropionic acid lactone; (7) Hydroxypropylmercaptoacetic acid lactone; (8) Hydroxyethylmercaptoacetic acid.
