The invention provides a method of sustained delivery of a lactam, imide, amide, sulfonamide, carbamate or urea containing parent drug by administering to a patient an effective amount of a prodrug compound of the invention wherein upon administration to the patient, release of the parent drug from the prodrug is sustained release. Prodrug compounds suitable for use in the methods of the invention are labile conjugates of parent drugs that are derivatized through carbonyl linked prodrug moieties. The prodrug compounds of the invention can be used to treat any condition for which the lactam, imide, amide, sulfonamide, carbamate or urea containing parent drug is useful as a treatment.

A process for the preparation of acylated secondary alcohol alkoxylates, said process comprising : (i) reaction of one or more internal olefins with one or more carboxylic acids in the presence of a catalyst composition in order to form one or more carboxylic acid esters; (ii) reaction of one or more carboxylic acid esters from step (i) with one or more alkylene oxide reactants, in the presence of a catalytically effective amount of a catalyst composition comprising: (a) one or more alkaline earth metal salts of carboxylic and/or hydroxycarboxylic acids and/or hydrates of the former; (b) an oxy-acid selected from sulphuric acid and ortho-phosphoric acid; (c) an alcohol and/or an ester; and/or products of the reciprocal reactions of (a), (b) and/or (c) in order to form one or more acylated secondary alcohol alkoxylates; and optionally (iii) hydrolysis or transesterification of one or more acylated secondary alcohol alkoxylates from step (ii) in order to form one or more secondary alcohol alkoxylates; and a process for making secondary alcohol alkoxy sulphates comprising the steps of: preparing secondary alcohol alkoxylates by the afore-mentioned process; and sulphating the secondary alcohol alkoxylates.

An erasable image forming material includes a color former, a developer, a binder resin, and a polymer decolorizer having an electron donating group capable of physically or chemically adsorbing the developer. This polymer decolorizer is, e.g., a polymer compound having a sugar skeleton, representatively starch. This image forming material can form sharp images and erase images by heat or a solvent to achieve a good erased state.

A decolorable image forming material containing a color former, a developer and a binder resin, in which the binder resin has a property that it is compatible with the color former when the material is in contact with a solvent and that it keeps the compatible state when the solvent is removed, or has a property that it shifts an equilibrium between the color former and the developer to a non-developed side when the temperature of the material is raised and that it keeps the state shifted to the non-developed side when the temperature of the material is lowered.
