  • Polyaminoamide which filters ultraviolet radiation
    Patent number: 5037901
    Abstract: Polyaminoamides of formula: ##STR1## in which A.sub.1 represents a divalent radical of structure: ##STR2## in which a and b=0 or 1 ##STR3## in which c and d=0 or 1 ##STR4## B.sub.1 represents: 1) in the proportions of 60 to 100% (in moles), the radical ##STR5## in which x.sub.2 =2 and n.sub.1 =1 or 2, or alternatively, x.sub.1 =3 and n.sub.1 =1 and e=0 or 12) in the proportions of 0 to 40% (in moles), the radical (II) above in which x.sub.1 =2 and n.sub.1 =0 or the radical ##STR6## 3) in the proportions of 0 to 20% (in moles), the radical--NH--(CH.sub.2).sub.6 --NH--;in radicals A.sub.1 and B.sub.1, Y represents a residue of an ultraviolet radiation-absorbing molecule, anda+b+c+d+e.gtoreq.1, it being understood that when a, b, c, d or e are zero, the nitrogen atom is then bound to a hydrogen atom;the ratio ##EQU1## is between 0.05 and 0.5; A.sub.2 represents a bivalent radical which has one of the following structures: ##STR7## B.sub.
