A photographically negative-working patternable mordant composition is disclosed containing a photocrosslinkable polymer comprised of, for providing both mordanting and crosslinking sites, repeating units of the formula:
wherein
Ar is an aromatic linking group,
R is a methylene group,
R¹ is independently in each occurrence a lower alkyl group,
R² is a divalent linking group,
X is a photocrosslinking group, and
Z is a charge balancing counter ion.
The mordant composition can be coated on a support to form a photographic element.
本发明公开了一种可负片成像的图案媒染剂组合物,该组合物含有一种可光交联聚合物,该聚合物由式中的重复单元组成,可同时提供媒染和交联位点:
其中
Ar 是芳香族连接基团
R 是亚甲基
R¹ 在每次出现时均独立地为低级烷基、
R² 是二价连接基团、
X 是光交联基团,以及
Z 是电荷平衡反离子。
媒染剂组合物可以涂布在支持物上,形成感光元件。
