Ink or coating compositions of low volatility

Claim 1

A liquid or paste composition comprising: I. -- from 5 to 35 weight percent of a melamine/formaldehyde resin or urea/formaldehyde resin, Ii.-- from 40 to 90 weight percent of an acrylate or methacrylate ester of an epoxidized fatty oil, said ester having vicinal hydroxyl groups and an average of at least two acrylate or methacrylate groups per mole thereof, Iii. -- from 5 to 55 weight percent of a different hydroxyl-containing polyacrylate or polymethacrylate ester having an average of more than one functional acrylate or methacrylate group in the molecule, Iv. -- a catalytic amount of a condensation catalyst sufficient to catalyze the condensation polymerization, and V. -- from 0 to 20 weight percent of a photoinitiator; said liquid or paste composition having a viscosity of from W to greater than Z on the Gardner-Holdt Scale.
