Method for the manufacture of a thermally processable imaging element

摘要

An improved method for manufacture of a thermographic or photothermographic element comprises the addition to the imaging composition of an amount sufficient to enhance the adhesive characteristics thereof of a polyalkoxysilane which has been pre-hydrolyzed in an organic solvent with a stoichiometric amount of water. A particularly suitable material is tetraethoxysilane which has been hydrolyzed in acetone with four moles of water for each mole of tetraethoxysilane.
