Claim 0:
1. The diaryloxybenzoheterodiazole compound disubstituted with thienothiophenic groups having general formula (Ia):, , wherein
Z represents a sulphur atom, an oxygen atom, a selenium atom; or an NR5 group wherein R5 is selected from C1-C20 alkyl groups, preferably C1-C8, linear or branched, or from optionally substituted aryl groups;
R1, R2 and R3, equal to or different from each other, represent a hydrogen atom; or are selected from C1-C20 alkyl groups, preferably C1-C8, linear or branched, optionally containing heteroatoms, optionally substituted cycloalkyl groups, optionally substituted aryl groups, C1-C20 alkoxy groups, preferably C1-C8, linear or branched, optionally substituted, —COOR6 groups wherein R1 is selected from C1-C20 alkyl groups, preferably C1-C8, linear or branched, or is a cyano group;
or R1 and R2, may optionally be bound together so as to form, together with the carbon atoms to which they are bound, a saturated, unsaturated, or aromatic cycle or a polycyclic system containing from 3 to 14 carbon atoms, preferably from 4 to 6 carbon atoms, optionally containing one or more heteroatoms such as oxygen, sulfur, nitrogen, silicon, phosphorus, selenium;
N4, equal to or different from each other, are selected from optionally substituted aryl groups.
