摘要:
A lithographic process comprises the steps of image-wise heating a presensitized lithographic printing plate and removing an unheated area of an image-forming layer to form a lithographic printing plate. The presensitized lithographic printing plate comprises a hydrophilic support and the image-forming layer. The image-forming layer contains a compound or a polymer having o-quinodimethane structures or precursor structures thereof. The lithographic printing plate is prepared by a reaction of the o-quinodimethane structures.
摘要:
A functionalized polymer containing a main chain derived from polyerizable monomers and pendent functional groups derived from isocyanates terminated with null or null ethylenically or acetyenically unsaturated groups. The functionalized polymer forms a good film and may be employed in industries where film forming polymers are used. Such industries include lithography, adhesives, electrophotoimaging, and the like. The functionalized polymers are self cross-linking and are suitable for use as polymer binders in both primary and secondary photoimaging compositions.

A resist resin containing a monomer unit selected from the group consisting of the following Formulas (I) and (II): 1 wherein each of R1 and R2 represents a hydrogen atom, alkyl group or acid-deprotectable protecting group respectively, and 2 wherein a substituent R3 represents an alkyl group, or a functional group comprising an acid-deprotectable protecting group, m representing the number of R3 is 0 (non-substitution), 1, 2 or more, R3 may be different from each other, provided that m is 2 or more, and n represents an integer of 0 to 4, has no rough spots on the surface after etching and so has good dry etching resistance, and therefore the resist resin is preferably used as a photo resist for DUV.

摘要:
A positive working printing form precursor comprises a thermally imagable composition which includes a hydroxyl group-containing polymer, for example a novolak resin. The composition has a weight of less than 1.1 gmnull2. It has been found that using a low weight of the composition on the precursor improves the properties of the precursor, in particular by rendering the sensitivity of the precursor to imaging radiation less variable over time.
摘要:
A negative working radiation sensitive resin composition comprising; an alkali-soluble novolak resin treated by fractionation and having 1,000 to 10,000 of weight average molecular weight as determined by polystyrene standard, where the portion with molecular weight of 500 or less is 5% or less in the total weight of the composition; a crosslinking agent; and a photo acid generator. This negative working radiation sensitive resin composition can be used preferably as etching resist, ion implantation resist, plating resist, LCD panel structural material such as spacer and electrode insulation material for an organic EL display because of having wide process margin, high heat resistance, high sensitivity, high resolution and good pattern shape.
摘要:
An imaging member, such as a negative-working printing plate or on-press cylinder, can be prepared with a hydrophilic imaging layer comprised of a heat-sensitive hydrophilic charged polymer (ionomer) and an infrared radiation sensitive negatively-charged oxonol dye that has a nullmax of greater than 700 nm. The heat-sensitive polymer and IR dye can be formulated in water or water-miscible solvents to provide highly thermal sensitive imaging compositions. In the imaging member, the polymer reacts to provide increased hydrophobicity in areas exposed to energy that provides or generates heat. For example, heat can be supplied by laser irradiation in the IR region of the electromagnetic spectrum. The heat-sensitive polymer is considered nullswitchablenull in response to heat, and provides a lithographic image without conventional alkaline processing.
