    Abstract: An imaging member, such as a negative-working printing plate or on-press cylinder, can be prepared using a hydrophilic imaging layer comprising a hydrophilic heat-sensitive polymer containing a crosslinking agent comprising ionic groups and epoxy groups. This polymer may comprise quaternary ammonium carboxylate groups which may include at least one substituted-alkylene(C1-C3)-phenyl group. The imaging member also includes an infrared radiation sensitive material to provide added sensitivity to heat that can be supplied by laser irradiation in the IR region. The heat-sensitive polymer may be “switchable” in response to heat, and provides a lithographic image without wet processing.

    Abstract: Imageable precursors for masks and for electronic parts comprise a polymeric layer applied to a substrate. The layer comprises at least one polymer having infra-red absorbing groups carried as pendent groups on the polymer backbone. Certain infrared absorbing groups may also act to insolubilize the polymer in a developer, until it is imagewise exposed to infra-red radiation. Imagewise application of heat, resulting from imagewise exposure of the precursor to infra-red radiation, renders the polymer layer more soluble in the developer than prior to exposure to the infra-red radiation.

    Abstract translation: 用于掩模和电子部件的可成像前体包括施加到基底的聚合物层。 该层包含至少一种聚合物，其具有在聚合物主链上作为悬挂基团携带的红外线吸收基团。 某些红外吸收基团也可以起作用以使显影剂中的聚合物不溶解，直到其成像曝光于红外辐射。 由于将前体成像曝光到红外辐射而产生的图像上的热量使得聚合物层比暴露于红外线辐射之前更易于在显影剂中溶解。

    Abstract: A method for imaging patterning compositions comprising the steps of: (1) providing at least one patterning composition layer on a substrate; said patterning composition comprising: (a) at least one acid generator; (b) at least one cross linking resin or compound; (c) at least one binder resin comprising a polymer containing reactive pendant group selected from group consisting of hydroxyl, carboxylic acid, sulfonamide, active imide, alkoxymethylamides and mixtures thereof; and (d) at least one infrared absorber; (2) imagewise exposing the patterning composition layer to actinic radiation; (3) treating the imaged patterning composition layer with heat energy to treat the imaged portions of the composition layer; (4) flood exposing the heat-treated, imaged patterning composition layer with UV light for a predetermined time, said time being sufficient to promote the effective clear-out of non-imaged portions during the developing step without causing substantial deterioration of the imaged portions; and (5) developing the flood exposed, heat-treated imaged patterning composition with an aqueous alkaline developer to remove the non-imaged areas of the patterning composition layer and leaving the imaged areas substantially unaffected.
