A radiation curable composition comprising: a) at least one monofunctional (meth)acrylate containing a carboxylic acid group, a phosphoric acid group or a phosphonic acid group; b) an acrylamide; c) at least one polyfunctional (meth)acrylate; characterized in that the radiation curable composition further comprises at least 0.1 wt % of a liquid penetrating controlling monomer selected from the group consisting of a C6-C20 alkyl (meth)acrylate, a fluorinated (meth)acrylate and a silicone (meth)acrylate.

Radiation curable composition for plating applications

A method of manufacturing an etched glass article including the steps of jetting an image with a UV curable inkjet ink on a surface of the glass article; curing the image; etching the surface not covered by the UV cured image to obtain an etched image; and solubilising the UV cured image in an aqueous alkaline solution.

Method of manufacturing an etched glass article

A method of manufacturing an etched glass article includes the steps of jetting an image with a UV curable inkjet ink on a surface of the glass article; UV curing the image; etching the surface not covered by the UV cured image to obtain an etched image; and removing the UV cured image in an aqueous alkaline solution; wherein the UV curable inkjet ink includes a polymerizable composition, wherein at least 80 wt % of the polymerizable composition consists of: a) 15.0 to 70.0 wt % of an acryl amide; b) 20.0 to 75.0 wt % of a polyfunctional acrylate; and c) 1.0 to 15.0 wt % of a (meth)acrylate containing a carboxylic acid group, a phosphoric acid group or a phosphonic acid group-; with all weight percentages (wt %) based on the total weight of the polymerizable composition.

A method for making a lithographic printing plate is disclosed which comprises the steps of: (1) providing a heat-sensitive lithographic printing plate precursor comprising on a support having a hydrophilic surface or which is provided with a hydrophilic layer, a heat-sensitive coating, (2) image-wise exposing said precursor with IR-radiation or heat, and (3) developing said image-wise exposed precursor with an alkaline developing solution, characterised in that a sludge inhibiting agent is present in said precursor or in said developing solution or in said precursor and said developing solution, and wherein said sludge inhibiting agent is a triazaindolisine compound. According to the above method, the formation of sludge is inhibited or reduced.
