Abstract

See full text

Medium molecular weight alcohols (for example aliphatic alcohols, such as trihydroxypentane and trihydroxyhexane, and aromatic alcohols, such as benzylalcohol) have been found to provide unexpected stability to dye and stain solutions. In addition, the use of these alcohols does not involve the negatives found in other dye stabilizers, for example extreme flammability and toxicity. The novel alcohols have been found to provide benefit to many dye systems.
