摘要： A thermally-responsive dispersant for an aqueous dispersion of positively- or negatively-charged or chargeable solid or liquid particulates, comprises a compound having an anchoring moiety linked to a thermally-responsive polymeric stabilizing moiety, other than a polyalkylene oxide, the polymeric moiety having a lower affinity for the surface than the anchoring group below the thermal transition temperature, the particulates being positively-charged or chargeable when the anchoring moiety contains an acid and/or hydroxy group and has a net acidity or neutrality and the particulates being negatively-charged or chargeable when the anchoring moiety has a basic group and has a net basicity, wherein the dispersion exhibits a change in sign from negative to positive and an increase in magnitude of a rheological property (viscosity at low shear and/or complex modulus at low amplitude oscillatory shear), on increasing the temperature from below to above the thermal transition temperature.

摘要： The invention provides a coating composition containing boehmite particles and a dispersant which comprises a compound having an anchoring moiety linked to a polymeric hydrophilic moiety, the anchoring moiety containing at least one acid and/or hydroxy group and having overall acidity or neutrality and the polymeric moiety having a lower affinity for a boehmite surface than the anchoring moiety. The anchoring moiety preferably contains at least two acid groups, preferably carboxylic acid groups, attached either in a [1,1], [1,2] or [1,3] relationship and is linked to the polymeric moiety, which is preferably derived from acrylamide or methacrylamide monomer units, preferably by a sulfur atom. The dispersant can reduce the viscosity of the boehmite dispersion and the tendency of the boehmite dispersion to increase in viscosity and/or form a gel or a yield stress material following periods of high shear stress.

摘要： The invention provides a dispersant for an aqueous dispersion of positively charged or chargeable solid particulates which comprises a compound having an anchoring moiety linked to a polymeric hydrophilic moiety, the anchoring moiety containing at least one acid and/or hydroxy group and having an overall acidity or neutrality and the polymeric moiety having a lower affinity for the particulate surface than the anchoring moiety. The anchoring moiety preferably contains at least two acid groups, preferably carboxylic acid groups, attached either in a [1,1], [1,2] or [1,3] relationship and is linked to the polymeric moiety, which is preferably derived from acrylamide or methacrylamide monomer units, preferably by a sulfur atom. The dispersant can reduce the viscosity of an aqueous dispersion of positively charged or chargeable solid particulates and can reduce the tendency of the resulting dispersion to form a gel or a yield stress material. The dispersant facilitates the processing of the resulting compositions in manufacturing operations and it may be used, for example, as a component of a coating material, a ceramic, paint, refractory material, filler or in an inkjet recording paper or film. Additionally, the dispersant can allow the use of higher concentrations of solid particulates and enable control of the yield stress, as some yield is often beneficial in helping prevent or reduce sedimentation.

摘要： A hydrophobically capped oligomeric acrylamide or pyrrolidone is employed as a dispersant for hydrophobic materials in an aqueous medium containing a hydrophilic colloid, e.g. gelatin. The hydrophobic materials include photographic addenda such as color couplers or solid particle dyes. Preferred dispersants have the general formula R—L—T   (1) or in which R, R1 and R2 are each independently selected from aliphatic hydrocarbyl, aryl-(aliphatic hydrocarbyl) and (aliphatic hydrocarbyl)-aryl groups, L is a sulphur atom or a linking group that contains a sulphur atom attached to the T group, and T is a hydrophilic oligomeric group obtained by the oligomerisation of one or more vinyl monomers having an amido function.

摘要： A method for the preparation of a lithographic printing plate comprises forming an oleophilic image on the surface of a hydrophilic support by depositing, preferably by ink-jetting, the image on the surface using an aqueous dispersion of an oligomer having in the molecule both hydrophilic and hydrophobic groups. The number of repeating units in the oligomer may be from 2 to 10 and the number of hydrophilic groups in the oligomer may also be from 2 to 10. Preferably the molecular weight of the oligomer is from about 500 to about 5000.
