    Abstract: A process for the production of coatings based on reaction products of (A) polyhydroxypolyacrylate resins obtained from hydroxyalkyl esters of acrylic acid and/or methacrylic acid, alkyl esters of acrylic acid and/or methacrylic acid, and one or more polymerizable, olefinically unsaturated nitrogen-containing heterocyclic compounds, with or without vinylaromatics, (meth)acrylamides and other monomers, with (B) isocyanurate-containing polyisocyanates which may or may not contain biuret groups, have a functionality of from 2.5 to 6 and consist of a mixture of polyisocyanates possessing predominantly cycloaliphatically bonded isocyanate groups with those possessing predominantly aliphatically bonded isocyanate groups. The process is particularly useful for coating metal components.

    Abstract: An apparatus for the production of exposed printing plates comprising a mold having a first wall formed by the support of the printing plate to be produced and a second wall formed by a glass plate covered with an image-bearing transparency; means for introducing a predetermined amount of a fluid photopolymerizable material under pressure into the mold, said predetermined amount substantially corresponding to the volume of the resin layer of the exposed printing plate to be produced; first and second members which are movable relative to one another, said first member carrying the glass plate and said second member carrying the support, movement of the said two members toward each other serving to close said mold; at least one source of actinic radiation located in such a way that the layer of fluid photopolymerizable material can be exposed through the glass plate; and means provided on the said second member for so adjusting the support that the latter's surface is equidistant from the surface of the glass plate, and maintaining the distance between the said two surfaces during exposure of the layer of fluid photopolymerizable material, said introducing means introducing the fluid photopolymerizable material into the mold under pressure, which causes the glass plate to bend or dome outwardly of the mold, and said support-adjusting means consists for so bending or doming the support that its bent or domed surface is equidistant from the bent or domed surface of the glass plate, and for maintaining the distance between the said two surfaces during exposure of the fluid photopolymerizable material through the glass plate using said source of actinic radiation. The apparatus of the invention can be manufactured and operated easily and economically.

    Abstract: A process for the production of coatings based on reaction products of (A) mixtures of (A1) polyhydroxypolyacrylate resins obtained from hydroxylalkyl esters of acrylic acid and/or methacrylic acid, alkyl esters of acrylic acid and/or methacrylic acid, and one or more polymerizable, olefinically unsaturated nitrogen-containing heterocyclic compounds, with or without vinylaromatics, (meth)acrylamides and other monomers, and (A2) polyesterpolyols with (B) isocyanurate-containing polyisocyanates which may or may not contain biuret groups, have a functionality of from 2.5 to 6 and possess predominantly cycloaliphatically bonded isocyanate groups, some of which may be replaced by aliphatically bonded isocyanate groups. The process is particularly useful for coating metal components.
