Alkoxylated lower alkyl fatty acid ester(s) are useful as solvents

摘要

Alkoxylated lower alkyl esters of fatty acids of formula R<1>CO(CH2CHR<2>O)nR<3> (1) are useful as a solvent for colouring agents in the form of microcapsules for the production of pressure sensitive carbonless copy paper. R<1>CO = 6-22C acyl group R<2> = H, CH3 R<3> = 1-4C alkyl n = 1-10.
