    Abstract: The invention is directed to methods of making an article bearing a relief image using a removable film. First, an imageable film that contains at least a mask substrate and an imageable material is imagewise exposed to imaging radiation to form an imaged film. The imaged film is then transferred to an imageable article, such as a flexographic printing plate precursor. The resulting assembly is exposed to curing radiation resulting in exposed and unexposed areas of photosensitive material on the imageable article. Following exposure to curing radiation, the imaged film is then removed from the imageable article. The imageable article is then developed with a suitable developer to form a relief image. The imaged film may then be reused to make additional articles bearing the relief image.

    Abstract translation: 本发明涉及使用可去除膜制造承载浮雕图像的物品的方法。 首先，将至少包含掩模基板和可成像材料的可成像膜成像曝光于成像辐射以形成成像膜。 然后将成像的膜转移到可成像的制品，例如柔版印刷版前体。 所得的组件暴露于固化辐射，导致可成像制品上的感光材料的暴露和未曝光的区域。 在暴露于固化辐射之后，然后将成像的膜从可成像的制品中取出。 然后用合适的显影剂显影可成像的制品以形成浮雕图像。 然后可以将成像的胶片重复使用以制造带有浮雕图像的附加物品。

    Abstract: Multilayer, positive working, thermally imageable, bakeable imageable elements are disclosed. The elements have a substrate, an underlayer, and a top layer. The underlayer comprises a resin or resins having activated methylol and/or activated alkylated methylol groups, such as a resole resin, and a polymeric material that comprises, in polymerized form about 5 mol % to about 30 mol % of methacrylic acid; about 20 mol % to about 75 mol % of N-phenylmaleimide, N-cyclohexylmaleimide, N-benzylmaleimide, or a mixture thereof; optionally, about 5 mol % to about 50 mol % of methacrylamide; and about 3 mol % to about 50 mol % of a compound represented by the formula: CH2C(R2)C(O)NHCH2OR1, in which R1 is C1 to C12 alkyl, phenyl, C1 to C12 substituted phenyl, C1 to C12 aralkyl, or Si(CH3)3; and R2 is H or methyl. The elements produce bakeable lithographic printing plates that are resistant to press chemistries.

    Abstract: The present invention provides a positive-working, thermally imageable element generally comprising a multi-layered imageable coating. The invention provides an imageable element comprising a substrate, an ink-receptive top layer, and an underlayer, the underlayer including a specific copolymer described herein. The copolymer can be a polymer comprising constitutional units derived from: a) a monomer having a cyclic urea group; b) a monomer comprising an N-substituted maleimide; c) a (meth)acrylamide or (meth)acrylate monomer; and d) a (meth)acrylic acid or vinyl benzoic acid monomer. In another embodiment, the copolymer can be a polymer comprising constitutional units derived from: a) a monomer having a cyclic urea group; b) a (meth)acrylic acid or vinyl benzoic acid monomer; c) and a (meth)acrylonitrile monomer. The imageable element may be used to prepare a lithographic printing plate that is resistant to press chemistry and can optionally be baked to increase press runlength.

    Abstract: An apparatus and method for providing substantially intimate rolling contact between a portion of a donor sheet and a portion of an acceptor element in a laser-induced thermal transfer printer comprises a rotatably mounted cylindrical drum, an acceptor element affixed to and supported by the cylindrical drum, a rotatably mounted dispensing roller for dispensing a donor sheet, and a rotatably mounted receiving roller for receiving the donor sheet, so that the donor sheet is extended between the dispensing roller and the receiving roller. A plurality of rotatably mounted contact rollers configured to bring a portion of the donor sheet extended between the dispensing roller and the receiving roller into contact with a portion of the acceptor element is also included. Alternatively, contact rollers need not be utilized, and the dispensing roller and receiving roller are configured to bring a portion of the donor sheet extended therebetween into contact with a portion of the acceptor element. The laser imaging head does not contact either the donor sheet or the acceptor element.
