摘要

Structurally colored polymers, formed by polymerizing monomers of the acrylic type, containing 0.5% to 20% by weight of dyestuff in copolymerized form or grafted form which have a number-average molecular weight between 1000 and 12,880 g. and contain m hydroxy functions and n groups of the formula: IMAGE in which X1 is hydrogen, chlorine, bromine or methyl; and R1 and R2 are the same or different and represent hydrogen, chlorine, methyl, phenyl, substituted phenyl or carboxyl; m being a number from 0 to 49 and n being a number from 2 to 70 such that the sum m+n is from 7 to 70 and the ratio m/n is from 0 to 2.4. These polymers are used in particular for the formation of colored coating on various supports and surfaces.
