Abstract: Condensation products prepared from cyclic carboxylic anhydrides of dicarboxylic acids, tricarboxylic anhydrides or tetracarboxylic anhydrides and difunctional polyamines, in particular polyoxyalkyleneamines, are suitable as a builder component for epoxy resin compositions. The reaction products based on tricarboxylic anhydrides or tetracarboxylic anhydrides are distinguished by having on average more than one imide group and carboxyl group per molecule. The compositions may optionally also contain condensation products obtained from tri- or poly-functional polyols and/or tri- or poly-functional amino-terminated polymers and cyclic carboxylic anhydrides, wherein the latter reaction products contain on average more than one carboxyl group per molecule. These compositions additionally contain conventional rubber-modified epoxy resins together with liquid and/or solid polyepoxy resins and conventional hardeners and accelerators and optionally fillers and rheology auxiliaries.

Abstract: The invention concerns the use of indoline derivatives of formula (I): in which R1, R2, R3, R4 and R5 independently of one another represent hydrogen or C1-4 alkyl groups, or R4 and R5 together with the oxygen atoms to which they are attached represent a C1-4 alkylenedioxy group, or of salts of such indoline derivatives, as additives to hair dyeing agents of the direct dyeing or primary intermediate/secondary intermediate type, thus producing hair dyeing with excellent color fastness characteristics.

Abstract: The introduction of vibration energy such as ultrasound into an uncured adhesive matrix during and/or after the joining of substrates leads to the effective dissolution and/or dispersion of adhesion-reducing contamination of the substrate surfaces into the adhesive matrix. In many cases, this can reduce the cost of expensive cleaning processes or quality control measures.

Abstract: A process for permanently deforming keratin fibers and compositions suitable for use in this process are provided. The process includes treating keratin fibers, before and/or after mechanically deforming the keratin fibers, with an aqueous reducing composition containing a keratin reducing substance, rinsing the keratin fibers with a rinse after contact with the reducing composition, and applying to the keratin fibers an aqueous fixing composition containing an oxidizing agent, where at least one of the reducing composition, the fixing composition, or the rinse is in the form of a two-phase or multiphase system. The two phase or multiphase system contains at least one oil component and/or at least one alcohol having limited miscibility with water and is capable of being converted at least temporarily with mechanical agitation into a homogeneous system for application to hair.

Abstract: A structural member having at least two non-coplanar surfaces is reinforced by providing a drop in insert between the surfaces. The insert is a carrier having an expandable structural foam intimately bonded to the carrier. When the foam is expanded, the foam becomes intimately bonded to the surfaces of the structural member to reinforce the structural member.

Abstract: A second agent composition for permanent wave treatment having a dyeing effect and a method for dyeing the hair which has been permanently waved. More particularly, a second agent composition for permanent wave treatment comprising a cationic dye having a quaternary nitrogen atom, which is optionally delocalizable, and a —X?N— bond wherein X represents a nitrogen atom or a —CH— bond, and a method for dyeing the hair which has been subjected to a permanent wave treatment using the cationic dye.

Abstract: A reinforced structural assembly comprises a structural member and a reinforcing member disposed adjacent to a wall of the structural member. The reinforcing member is an insert having a carrier portion and an expandable portion in the form of a one-part epoxy system having an outer surface disposed toward the wall of the structural member. The epoxy system contains in weight percent about 30% to about 70% epoxy resin and contains a filler in the form of hollow glass microspheres. The epoxy system is in the form of a high-viscosity dough so that in its uncured state it does not significantly flow from and remain supported by the carrier portion of the insert whereby the insert may be placed near the wall before the epoxy dough is cured to bond the dough to the wall when the dough is cured and expands into intimate contact with the wall.

Abstract: A method for coloring Keratin-containing fibers which comprises applying a composition containing a compound of formula A—CH?B—CH?A???(I).

Abstract: This invention relates to adhesive compositions of which the binder system contains nanoscale particles with ferromagnetic, ferrimagnetic, superparamagnetic or piezoelectric properties. The invention also relates to dissolvable adhesive bonds and to a process for dissolving adhesive bonds.

Abstract: A method of nondestructive, reversible fixing of a coherent layer to a substrate, comprising the steps of anchoring a nonfibrous coherent layer to a film having either or both of projecting or embedded anchoring elements, wherein the anchoring elements provide mechanical anchorage of the coherent layer to the film, and fixing the coherent layer and film to the substrate. The coherent layer is anchored by applying a liquid or paste form material to the substrate that sets on the substrate to form the coherent layer, which is nonadhesive or only slightly adhesive to the film.

Abstract: The invention relates to a method of producing soluble polymer granules which are suitable for use in washing and/or cleaning surfactants. According to said method, an aqueous preparation of the polymer which contains at least 30% by weight polymer, optionally in admixture with other washing and/or cleaning surfactant ingredients, is granulated and at the same time dried batchwise or continuously, preferably continuously, in a circular fluidized bed. In said fluidized bed, an eddy flow about the vertical axis of the apparatus is produced above the ground of the fluidized bed by means of an air inlet. The invention also relates to soluble, spherical polymer granules with a polymer content of 50 to 95% by weight and to washing or cleaning surfactants containing the inventive granules.
