ABSTRACT:
The present invention is a method of producing an imaging support which includes providing a support, simultaneously coating on a side of the support; a transparent magnetic recording layer including magnetic particles, a polymeric binder and an organic solvent, and a lubricating overcoat layer farthest from the support, the lubricating overcoat layer including a lubricant selected form the general formulas I, II or III:
wherein general formula I comprises: ##STR1## wherein X is selected from the group consisting of esters, amides, ethers, or methylene, a is from 10 to 500, and b is from 4 to 3000, and the general formula I has a molecular weight at least 800;
wherein general formula II comprises: ##STR2## wherein Y is selected from the group consisting of, --C-- and --N--, Z is selected from the group consisting of esters, amides, and a carbon-carbon bond, R is selected from the group consisting of methyl, and hydrogen or may be absent if Y equals nitrogen, c is from 1 to 2, d is from 4 to 3000, e is from 10 to 30, and the general formula II has a molecular weight of from 800 to 500,000, preferably from 3000 to 100,000;
wherein general formula III comprises: ##STR3## wherein R' is selected from the group consisting of methyl, phenyl, substituted aliphatic groups, unsubstituted aliphatic groups, substituted aromatic groups, and unsubstituted aromatic groups; wherein f is from 4 to 3000, and g is from 10 to 30, and the general formula III has a molecular weight of from about 800 to 500,000 and preferably are between 3000 and 100,000, and an organic solvent. The present invention also includes a photographic element produced by the method.
