Abstract
A photographic film base comprising a polyester support have a photo-grafted layer of a monomer having a formula selected from: ##STR1## where R.sub.1 is --OX or --NX.sub.2 ; each R.sub.2 is independently selected from X; R.sub.3 is X, --COOX or --CONX.sub.2 ; R.sub.4 is --CHX--, --NH-- or --O--; R.sub.5 is --CHX-- or ##STR2## R.sub.6 is X or --(CH.sub.2).sub.n --COOX, where n is an integer of from 1 to 4 carbon atoms; and each X is independently selected from hydrogen or lower alkyl having 1 to 4 carbon atoms.

A photographic film base comprising a poly-ester support having a photo-grafted layer of a monomer having a formula selected from:
- ##STR6## where R.sub.1 is --OX or --NX.sub.2 ;
- each R.sub.2 is independently selected from X;
- R.sub.3 is X, --COOX or --CONX.sub.2 ;
- R.sub.4 is --CHX--, --NH-- or
- R.sub.5 is --CHX-- or ##STR7## R.sub.6 is X or --(CH.sub.2).sub.n --COOX, where n is an integer of from 1 to 4 carbon atoms;
- and
- each X is independently selected from hydrogen or alkyl having 1 to 4 carbon atoms.
A process of making a photographic film base which comprises providing a polyester sheet, applying to the sheet a photo-graftable layer of a monomer having a formula selected from ##STR11## where R.sub.1 is --OX or --NX.sub.2 ;
- each R.sub.2 is independently selected from X;
- R.sub.3 is X, --COOX or --CONX.sub.2 ;
- R.sub.4 is --CHX--, --NH-- or --O--;
- R.sub.5 is --CHX-- or ##STR12## R.sub.6 is X or --(CH.sub.2).sub.n --COOX, where n is an integer of from 1 to 4 carbon atoms;
- and each X is independently selected from hydrogen or lower alkyl having 1 to 4 carbon atoms.
