INHERENTLY COLORED POLYUREA AND POLYURETHANE

摘要

This invention relates to copolymer compositions having pigment like properties, comprising a fluorescent or non-fluorescent dye attached to a polyurea or polyurethane chain by a spacer.The invention also provides for new monofunctional dye monomers comprising an isocyanate group attached to a dye moiety by a spacer comprising a urea or urethane group.The polymer pigments provide excellent properties, especially high temperature stability and easy applicability as colorant in different standard polymers.
