The new diaminopyrazole compounds are bridged 4,5-diaminopyrazole compounds or salts thereof. These diaminopyrazole compounds have the formula (I): n n n wherein R1 represents hydrogen, a C 1 - to C 6 -alkyl, a C 1 - to C 4 -hydroxyalkyl, a C 1 - to C 4 -aminoalkyl, a C 1 - to C 8 -alkylamino, a di(C 1 - to C 8 -alkyl)amino, a C 1 - to C 4 -alkylamino-(C 1 - to C 4 -alkyl), a di(C 1 - to C 4 -alkylamino)-C 1 - to C 4 -alkyl, an aryl or a heteroaryl; R2 and R3 each represent hydrogen, a straight-chain or branched C 1 - to C 6 -alkyl, an aryl, a heteroaryl, a carboxylic acid, a carboxylic acid ester, an unsubstituted or substituted carboxylic acid amide, a hydroxy or a C 1 - to C 4 -hydroxyalkyl group, or R2 and R3 together represent a C 1 - to C 6 -alkylene group; Z represents a C 1 - to C 10 -alkyl diradical, optionally interrupted by a heteroatom, an aromatic or heteroaromatic diradical, optionally substituted with a hydroxy group, a C 1 - to C 6 -alkyl group and/or is subjected to a benzocondensation once or twice; or Z is —Ar(Alk) n —Ar—, wherein Ar represents an arylene group or a heteroarylene group, Alk represents a —CH 2 — group and n is 0 to 6; and x and y are 0 or 1. |
