<p>The invention provides a compound of formula (I) in which R?1 and R2¿ are independently hydrogen, (C¿1?-C7)-alkyl, (C2-C7)-alkenyl, or (C2-C7)-alkynyl; X?1 and X2¿ can be independently present or absent, and if present are independently (C¿1?-C7)-alkylene or (C2-C7)-alkenylene; Y?1 and Y2¿ are independently (C¿4?-C8)-cycloalkylene or (C4-C8)-cycloalkenylene, which are unsubstituted or substituted by up to four identical or different radicals selected from (C1-C7)-alkyl, (C2-C7)-alkenyl, or carboxyl; and Z is (C1-C12)-alkylene; (C2-C12)-alkenylene; D-E-F, where D and F are independently (C1-C12)-alkylene or (C2-C12)-alkenylene, and E is (C4-C8)-cycloalkylene or (C4-C8)-cycloalkenylene, which are unsubstituted or substituted by up to four identical or different radicals selected from (C1-C7)-alkyl or (C2-C7)-alkenyl; or G-H-I, where G and I are independently (C1-C12)-alkylene or (C2-C12)-alkenylene, and H is N-(C1-C7)-alkyl; N-(C2-C7)-alkenyl; N-(C4-C8)-cycloalkyl or N-(C4-C8)-cycloalkenyl, which are unsubstituted or substituted by up to four identical or different radicals selected from (C1-C7)-alkyl or (C2-C7)-alkenyl; or N-(C1-C7)-alkyl-(C4-C8)-cycloalkyl, which is unsubstituted or substituted by up to four identical or different radicals selected from (C1-C7)-alkyl or (C2-C7)-alkenyl.</p> |
