THERMOPLASTIC FLUORESCENT PIGMENT

The invention relates to a thermoplastic fluorescent pigment obtained by the condensation of a diisocyanate prepolymer and an aliphatic diamine, a cycloaliphatic diamine or a mixture of a diamine and a polyol in the presence of a fluorescent dye, wherein the prepolymer is obtained by the reaction of...

Beschreibung
Zusammenfassung:	The invention relates to a thermoplastic fluorescent pigment obtained by the condensation of a diisocyanate prepolymer and an aliphatic diamine, a cycloaliphatic diamine or a mixture of a diamine and a polyol in the presence of a fluorescent dye, wherein the prepolymer is obtained by the reaction of an aromatic sulfonamide with an excess of aliphatic, cycloaliphatic and/or or aromatic diisocyanate, and wherein the molar excess of diisocyanate in the prepolymer equals the molar amount of the aliphatic diamine, the cycloaliphatic diamine or the mixture of a diamine and polyol present in the condensation suspension. L'invention porte sur un pigment fluorescent thermoplastique obtenu par condensation d'un prépolymère de diisocyanate et d'un diamine aliphatique, d'un diamine cycloaliphatique ou d'un mélange d'un diamine et d'un polyol en présence d'un colorant fluorescent ; le prépolymère est obtenu par la réaction d'un sulfonamide aromatique avec un excédent de diisocyanate aliphatique, cycloaliphatique et/ou aromatique. L'excédant molaire du diisocyanate dans le prépolymère est égal à la quantité molaire du diamine aliphatique, du diamine cycloaliphatique ou du mélange d'un diamine et du polyol présents dans la suspension de condensation.
