An ink jet recording element comprising a support having thereon the following layers in order:
- i) a base layer comprising a polymeric binder, a polymeric mordant and a stabilizer having the following formula:
- wherein:
- each R individually represents a substituted or unsubstituted alkyl or alkoxy group having from about 1 to about 7 carbon atoms;
- a phenyl group having from about 6 to about 10 carbon atoms;
- a phenoxy group having from about 6 to about 10 carbon atoms;
- a carbonamido group having from 1 to about 8 carbon atoms;
- or two or more R groups can be combined together to form a ring structure;
- n is 1 to 4;
- L is a linking group containing at least one carbon atom;
- and
- M30 is a monovalent cation;
- with the proviso that the total number of carbon atoms in all the R's and L taken together is at least 3, and at least one R is alkoxy group;
- and
- ii) an overcoat layer comprising a trisaryl-1,3,5-triazine ultraviolet light absorbing material.
