Photographisches Element

摘要

A photographic element comprising a support having thereon at least one layer comprising a polymer obtained by copolymerizing a repeating unit represented by the following general formula (I) and a copolymerizable cellulose derivative represented by the following general formula (II): wherein A represents a repeating unit derived from an ethylenically unsaturated monomer having -COOH group, -SO3H group or -PO(OH)2 group in the molecular structure; and B represents a repeating unit derived from a copolymerizable ethylenically unsaturated monomer; wherein (R<1>)s each independently represents (i) a hydrogen atom, (ii) a monovalent organic bonding group such as an ester group or an ether group or (iii) a monovalent organic bonding group represented by the following general formula (III), with the proviso that (R<1>)s do not all hydrogen atom at the same time; and n represents a number of 20 to 800; wherein R<2> represents hydrogen atom or an alkyl group having 1 to 6 carbon atoms; and L represents a bivalent organic bonding group, and wherein the percentage by weight of the component represented by general formula (I) in the copolymer is from 5 to 95; the percentage by weight of the component represented by general formula (III) based on the weight of the component represented by general formula (II) is from 0.00001 to 10; x and y represent each the percentage by weight of each monomer component in the copolymer and x is in the range of 1 to 95 and y is in the range of 5 to 99.
