    摘要： A composition for absorption refrigeration which comprises a fluorinated hydrocarbon refrigerant, an amide or glycol ether solvent serving as an absorption liquid, and a phosphite stabilizer. The stabilizer is used in an amount of 0.05 to 0.5 wt % of the absorption liquid calculated as phosphorus, within which range the phosphite stabilizer can suitably protect the refrigerant and the absorption liquid from deteriorating and decomposing at high operation temperatures.

    摘要： The present invention provides a novel photochromic material which is capable of forming two kinds of aggregates, each having a sharp absorption peak at a different wavelength. The photochromic material comprises a spiropyran compound represented by the following general formula: ##STR1## wherein R.sup.1 and R.sup.2 are independently alkyl groups each containing 1 to 30 carbon atoms, and R.sup.3, R.sup.4, R.sup.5, and R.sup.6 are independently selected from the group consisting of hydrogen, an amino group, an alkoxy group with 1 to 5 carbon atoms, and an alkylamino group with 1 to 5 carbon atoms with the proviso that at least one of R.sup.3, R.sup.4, R.sup.5, and R.sup.6 is an amino group, an alkoxy group or an alkylamino group.
