Abstract: Composition comprises: (i) at least one ureidopyrimidone compounds (A); and (ii) at least one 4-carboxy 2-pyrrolidinone derivative (B) or its salts, optical isomers, stereoisomers, enantiomers and diastereoisomers, or geometrical isomers. Composition comprises: (i) at least one ureidopyrimidone compounds (A) of formula (I) or (II); and (ii) at least one 4-carboxy 2-pyrrolidinone derivative of formula (B) or its salts, optical isomers, stereoisomers, enantiomers and diastereoisomers, or geometrical isomers. n : 1-3, preferably 1; m : 0 or 1; w, q : 0 or 1, which is determined by the nature of the groups A1 and A2; R1, R2 : H, -OH, -NRR1a, or optionally saturated and aromatic 1-18C alkyl containing one or more heteroatoms of O, S or N; R1 : -Z1a-A1; Z : a multivalent radical (divalent with tetravalent, according to the value of n) comprising (i) carbon-based radical, preferably optionally saturated 1-32C hydrocarbon (optionally interrupted or substituted, one or more times, by optionally aromatic 3-12C (hetero)cycle group), (ii) optionally aromatic 3-12C (hetero)cyclic hydrocarbon (optionally substituted by one or more carbon groups, preferably optionally saturated 1-32C hydrocarbon), or (iii) 5-6C-cycloalkyl-1-12C alkyl group, where the groups (i)-(iii) are optionally substituted with -OH, -SO 3R, -OSO 3R, -SO 3H, -OSO 3H, -COOH, -COOR, -CONRR1a, 1-4C alkyl, or -N +>RR1aR2a, or An ->, and/or interrupted or terminated by 1-5 groups comprising -S-, -NH- (=NH), -O-, -C(O)-, -SO 2-, -NHC(O)-, -C(O)NH- , -OC(O)-, -C(O)O-, piperazine groups of formula (a), pyridine groups of formula (b)-(d), -NR1a-, (-N +>R2aR1a)(An ->), trazine group of formula (e), imidazole groups of formula (f); Raa : H, halo (preferably Cl) or 1-6C alkyl; R, R1a, R2a : H or 1-12C alkyl group, provided that the Z comprises at least one heteroatoms of N, O or S, and when Z is interrupted or substituted by a cationic group of electroneutrality of (I) is provided by an anion or its mixtures (An ->); Z1, Z1a : divalent radical Z0; Z0 : a covalent bond of (I) when n is 1 and q is 0, Z1a can not be a covalent bond; Z2 : 1-32C divalent radical, provided that when w is 0, then A1 and A2 are not terminated by N; A1 : para-aminobenzoate group of formula (IIIa) (where w is 1), cinnamate, benzalmalonate or cyanoacrylate group of formula (IVa) (where x is 0 or 1), benzophenone group of formula (Va) (where w is 1), benzylidenecamphor group of formula (VIa) (where w is 1), (VIIa) (where w is 0) or (VIIIa) (where w is 0), benzotriazole group of formula (IXa) (where q and w are 1), (Xa) (where q is 0, X is O or NH) or (XIa) (where q is 1, and w is 0), or s-triazine group of formula (XIIa) (where w is 0); A2 : para-aminobenzoate group of formula (IIIb) (where w is 1 and X is O or NH), cinnamate, benzalmalonate or cyanoacrylate group of formula (IVb) (where w is 1 and X is O or NH), benzophenone group of formula (Vb) (w is 0), benzylidenecamphor group of formula (VIb) (w is 0), or s-triazine group of formula (VIIb) (w is 0); A3, A4 : (IIIa)-(VIa) or (IXa). In formula (IIIa)-(XIIa) and (IIIb)-(VIIb): Ak : saturated divalent 1-6C, preferably 2C alkyl; R1 : 1-30C alkyl, 3-30C alkenyl containing one or more hydroxyl substituents and an alkyl ring in the carbon chain, one or more heteroatoms comprising O, N or Si, or optionally substituted 6-20C aryl; either R2, R2a : 1-10C alkoxy, 1-10C alkyl, 2-8C alkenyl or-OSi(CH 3) 3; or R2R2 : alkylidenedioxy group in which the group alkylidene contains 1-2C (i.e. -O-(CH 2) t-O-); t : 1 or 2; p, p1 : 0-2; R3 : H, 1-4C alkyl, or a group comprising -(C=O)XR1, -CN, -(C=O)R1, or R1-SO 2R4; R4 : 1-12C alkyl, or optionally substituted 6-20C aryl; R5 : a divalent 2-8C alkyl group; X : O or -NR6; and R6 : 1-8C alkyl. In formula (B): R3 : H, 1-20C alkyl, linear or branched 3-20C alkyl; R4 : linear 1-20C or branched 3-20C alkyl containing 5-6C ring, branched 3-20C alkyl, 5-6C cycloalkyl optionally substituted by one or two methyl groups, phenyl, benzyl or phenethyl group; and R5, R6 : H, linear 1-12C or branched 3-12C alkyl, when R3 is H, then (B) is in the form of free acid or its salt.
