Abstract

Procedure for obtaining desensitizing compositions to desensitize a developer against coloration of a substantially colorless color former in recording materials, characterized in that the developer is reacted with a composition containing at least one N- (aminoalkyl) -lactam of the next general formula **(See formula)** where n is from 2 to 11, m is from 2 to 6 and each methylene group can be substituted with an alkyl group or an aryl group, or a derivative of said N- (aminoalkyl) -lactam.
