Claim:
A laundry or dishwasher detergent tablet having at least one cavity, said cavity having a base and lateral boundary walls, said tablet comprising 5.5% to 25% by weight, based on the tablet, of one or more nonionic surfactants with a melting point above 20° C., wherein the cavity base and lateral boundary walls form a non-orthogonal angle greater than 90° further comprising 0.1% to 70% by weight of copolymers of i) unsaturated carboxylic acids; ii) monomers containing sulfonic acid groups; and iii) optionally other ionic or nonionic monomers, wherein the copolymers comprises structural units corresponding to formulae VII, VIII, IX, X, XI and/or XII: —[CH 2 —CHCOOH] m —[CH 2 —CHC(O)—Y—SO 3 H] p — (VII) —[CH 2 —C(CH 3 )COOH] m —[CH 2 —CHC(O)—Y—SO 3 H] p — (VIII) —[CH 2 —CHCOOH] m —[CH 2 —C(CH 3 )C(O)—Y—SO 3 H] p — (IX) —[CH 2 —C(CH 3 )COOH] m —[CH 2 —C(CH 3 )C(O)—Y—SO 3 H] p — (X) —[HOOHCCH—CHCOOH] m —[CH 2 —CHC(O)—Y—SO 3 H] p — (XI) —[HOOCCH—CHCOOH] m —[CH 2 —C(CH 3 )C(O)O—Y—SO 3 H] p — (XII) in which m and p are whole natural numbers of 1 to 2,000 and Y is a spacer group selected from substituted or unsubstituted aliphatic, aromatic or araliphatic hydrocarbon radicals containing 1 to 24 carbon atoms.
