Abstract
Abstract Structurally dyed random polymers and copolymers characterized in that their chain comprises a dye of the formula: ##STR1## wherein the residue --CH═CH--CN is fixed in position 4 or 5, X represents a hydrogen or halogen atom, the benzene ring A can be substituted by halogen atoms, alkyl, alkoxy or acylamino groups, m represents 0 or 1 and B represents the residue of a coupling component, either substituted or unsubstituted and which is free of sulfonic or carboxylic acid groups. Such dyed polymers and copolymers are intensely dyed and useful for making yarns, molded articles, varnishes, synthetic resins, synthetic fibers, and the like. The dye forms an integral part of the chain structure of the polymers and copolymers.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
124 words
Structurally dyed random polymer or copolymer resulting from the radical polymerization of one or more colorless base monomers having a polymerizable olefinically unsaturated group and one or more dyes of the formula: ##STR4## wherein --CH═CH--CN is fixed in position 4 or 5, X represents a hydrogen or halogen atom, the benzene ring A is unsubstituted or substituted by halogen atoms, alkyl, alkoxy or acylamino groups, m represents 0 or 1, and B represents the residue of a coupling component BH either substituted or unsubstituted, said coupling component being free of sulfonic and carboxylic acid groups, said polymerization taking place across the double bond of the cyanovinyl group of the dye and the double bond of the polymerizable olefinically unsaturated group of the base monomers.
Claim 2
Dependent Claim
124 words
Structurally dyed random polymer or copolymer resulting from the radical polymerization of one or more colorless base monomers having a polymerizable olefinically unsaturated group and one or more dyes of the formula: ##STR4## wherein --CH═CH--CN is fixed in position 4 or 5, X represents a hydrogen or halogen atom, the benzene ring A is unsubstituted or substituted by halogen atoms, alkyl, alkoxy or acylamino groups, m represents 0 or 1, and B represents the residue of a coupling component BH either substituted or unsubstituted, said coupling component being free of sulfonic and carboxylic acid groups, said polymerization taking place across the double bond of the cyanovinyl group of the dye and the double bond of the polymerizable olefinically unsaturated group of the base monomers.
