A method for the preparation of a flexographic printing plate is disclosed. In this method an ink jet image is used as mask for the exposure of a flexo plate precursor. The ink jet recording material is composed of several layers and comprises a binder, a cationic mordant and a spacing agent in its top layer.

Preparation of a flexographic printing plate

An improved ink jet recording element is disclosed comprising a subbed polyester support, and an ink receiver layer containing a cationic compound, characterized in that between said support and said ink receiver layer there is an additional adhesion promoting layer present comprising a binder and a cationically modified silica.

Recording element for ink jet printing

An improved ink jet recording material is disclosed. It comprises on the front side of a subbed polyester at least two ink-receiving layers based on polyvinyl alcohol with a top layer containing a cationic mordant, and on the back side a double layer one of which contains an electronically conductive polymer.

Ink jet recording material and its use

A substantially light-insensitive black and white monosheet thermographic recording material comprising a support and a thermosensitive element provided with a protective layer, the thermosensitive element containing a substantially light-insensitive organic silver salt, a 1,2-dihydroxy-benzene derivative in thermal working relationship therewith and a first polymer having active hydrogen atoms at least part of which has reacted with a first polyisocyanate selected from the group consisting of: hexamethylene diisocyanate, toluene diisocyanate, diphenylmethane diisocyanat, naphthylene diisocyanate and triphenylmethane-p,p&prime;,p&Prime;-trityl triisocyanate; and the protective layer being exclusive of fluorine-containing compounds; and a thermographic recording process therefor.

Substantially light-insensitive black and white thermographic recording material with improved image tone

A substantially light-insensitive black and white monosheet thermographic recording material comprising a support and a thermosensitive element containing a substantially light-insensitive organic silver salt, a 1,2-dihydroxyphenyl-compound in thermal working relationship therewith and a binder, wherein the 1,2-dihydroxyphenyl-compound is represented by formula (I):
