Abstract

Procedure for obtaining sensitizer compositions for application in recording materials, characterized in that an amidine derivative is obtained by the reaction of an amidine, which has the general formula (I) **(See formula)** where R1 and R2 each represent an alkyl group having 1 to 8 carbon atoms, R1 and R2 can form a C2 to C11 ring which can be replaced by alkyl groups having 1 to 4 carbon atoms and n represents 2 to 6, and a phenol, a carboxylic acid, carbonic acid, or phosphoric acid.
