Provided are a conductive composition for thin film printing and a method for forming a thin film conductive pattern, which can easily performing thin film printing, and can capable of improve conductivity by thermal sintering at a comparatively low temperature of 300&#xb0; C. or less or by photo irradiation. A conductive composition comprises metal particles, a binder resin, and a solvent, the content of an organic compound in the solvent being 5 to 98% by mass, the organic compound comprising a hydrocarbon group having a bridged cyclic structure and a hydroxyl group, the content of metal particles being 15 to 60% by mass, the metal particles containing 20% by mass or more of flat metal particles, the content of the binder resin being 0.5 to 10 parts by mass relative to 100 parts by mass of the metal particles, and the viscosity at 25&#xb0; C. being 1.0&#xd7;10to 2&#xd7;10mPa&#xb7;s. The composition is printed in a pattern having any selected shape on a substrate, by screen printing, and the pattern is subjected to thermal sintering at a temperature of 300&#xb0; C. or less and/or subjecting the pattern to pulsed light irradiation.

A lower fatty acid ester such as ethyl acetate or ethyl acrylate is prepared by a process in which a lower fatty acid such as acetic acid or acrylic acid is reacted with a lower olefin such as ethylene by using as solid catalyst a heteropoly-acid or its salt. The esterification is carried out in gaseous phase.
