Method for forming an improved imaging support element including amine reactive side groups and element formed therewith

A method for producing an imaging support element comprising the steps of:

• (a) forming a coating over a polymeric film support, the coating including a copolymer comprising at least one non-amine reactive comonomer and at least one comonomer having amine reactive side groups, the amine reactive side groups being present in a density of at least 1010 sites per cm2;
• and
• (b) heat treating the polymeric film support with the coating thereon at a temperature of from about 50° C. below the glass transition temperature (Tg) of the polymeric support up to the glass transition temperature (Tg) of the polymeric support.

An imaging element support comprising:

• (a) a polymer support;
• and
• (b) a subbing layer coated on said polymer support, the subbing layer including a copolymer comprising at least one non-amine reactive comonomer and at least one comonomer having amine reactive side groups, the subbing layer including amine reactive groups in a density range of at least 1010 sites per cm2, the polymer support with the subbing layer thereon having been heat treated at a temperature of from about 50° C. below the glass transition temperature (Tg) of the polymeric support up to the glass transition temperature (Tg) of the polymeric support.
