Dyes, Macromolecular (original) (raw)

2002, Encyclopedia of Polymer Science and Technology

Macromolecular dyes are a group of compounds thought of as intrinsically or structurally colored polymers, ie, possessing inherent properties. Their applications are markedly dependent on their relatively high molar mass. Thus, macromolecular dyes are useful polymers or oligomers as well as useful dyes with high tinctorial strength. They are soluble in the medium in which they are applied. Closely related themes include macromolecular chromophores, macromolecular pigments, macromolecular colorants, monomeric colorants and monomeric chromophores. There are difficulties associated with the definition of the word dye and the definition of the word macromolecule. For example, it is useful to consider, perhaps with respect to the intended application and the associated molar mass, when the molecular species can justifiably considered to be macromolecular. Thus, some flexibility in terminology is used in the review that is presented here. There are several reports that provide a useful introduction to the general topic and to the various applications to which these types of material can be put .
