Abstract: The present invention provides compounds that have antimalarial activity. More in particular, the present invention provides novel compounds that are analogues of pantothenamides. The pantothenamide analogues of this invention have particularly low IC50 values against the asexual blood stages and gametocytes of malaria parasites. Furthermore, the pantothenamide analogues of this invention are characterized by low hepatic metabolism. Therefore, pantothenamide analogues of the invention are particularly suitable for use in therapeutic and/or prophylactic treatment of protozoan infections in a human or animal subject in need thereof. The invention further provides pharmaceutical formulations comprising the pantothenamide analogues as well as the therapeutic and/or prophylactic uses of the pantothenamide analogues and pharmaceutical formulations comprising them.

Abstract: The invention relates to an aqueous impregnating resin solution containing (A) between 77.5 and 99.8 wt. %, in relation to the impregnating resin solution, of aqueous condensates based on melamine and formaldehyde; (B) between 0.1 and 20 wt. %, in relation to the impregnating resin solution, of at least one specific quaternary ammonium compound; and (C) between 0.1 and 2.5 wt. %, in relation to the impregnating resin solution, of an aqueous hardener solution. The invention also relates to an aqueous impregnating resin solution consisting of constituents (A) and (B), and to an aqueous hardener mixture consisting of constituents (B) and (C). The invention further relates to an impregnating resin film containing fibrous substances containing cellulose and impregnated with the aqueous impregnating resin solution, and to the use of the aqueous impregnating resin solution, or impregnating resin film, for the antistatic finishing of coated materials.

Abstract: The present invention relates to the use for coating three-dimensionally structured surfaces and/or moldings of melamine resin sheets and/or films produced from cellulosic fiber materials post- or pre- and post-impregnated with an aqueous solution comprising (i) a melamine-formaldehyde condensate, (ii) an etherified melamine-formaldehyde condensate, and (iii) a polymer dispersion.

Abstract: The present invention relates to a process for the production of laminated substrates having a three-dimensionally structured surface, wherein a decorative paper which comprises from 5 to 90% by weight, based on the total fiber content, of fibers of synthetic polymers is impregnated with a crosslinkable aminoplast resin, applied to the substrate and three-dimensionally shaped. Furthermore, the invention relates to aminoplast resin sheets or films, and the use of a modified decorative paper for the production of aminoplast resin sheets or films for 3D lamination.

Abstract: Aqueous melamine resin dispersions comprise as discontinuous phase a melamine resin stabilized with a combination of a cationic protective colloid and an anionic protective colloid.

Abstract: An aqueous resin solution for the impregnation of paper webs contains 2-40 parts by weight of a polyurea composed of urea and of a polyamine per 100 parts by weight of a melamine/formaldehyde precondensate. The impregnated paper webs are suitable for coating woodbase materials, especially chipboard.

Abstract: Amino resin solutions having an electrical conductivity of <100 .mu.S/cm for impregnating paper are obtainable byA) methylolation of melamine with aqueous formaldehyde in a molar ratio of from 1:2 to 1:5 in the presence of a tertiary organic amine at a pH of from 7 to 12,B) etherification with a molar excess, based on the methylol groups, of a C.sub.1 -C.sub.4 -alcohol in the presence of an unsubstituted or substituted dicarboxylic acid and/or polycarboxylic acid at a pH of from 3 to 6,C) neutralization of the reaction mixture with an inorganic base and removal of the volatile components by distillation, except for a water content of <10% by weight, based on the reaction mixture, andD) addition of a C.sub.1 -C.sub.4 -alcohol to give a solids content of from 40 to 90% by weight, based on the amino resin solution, and removal of insoluble components by filtration.
