Abstract

The present invention relates to IR-sensitive compositions containing an initiator system comprising: PA1 (a) at least one compound capable of absorbing IR light PA1 (b) at least one compound capable of producing radicals and PA1 (c) at least one polycarboxylic acid comprising an aromatic moiety substituted with a heteroatom selected from N, O and S and also at least two carboxyl groups wherein at least one of the carboxyl groups is bonded to the heteroatom via a methylene group. These compositions are inter alia extraordinarily suitable for the manufacture of printing plates.
