ABSTRACT:
Solvents useful to dissolve dyes employed in pressure-sensitive copying systems comprise compositions of monobenzylated, dibenzylated and, optionally, tribenzylated xylenes having defined isomeric configurations. Benzylated meta-xylene; benzylated para-xylene; and benzylated meta-para-xylene are low-odor solvents.
