A resin coated sheet type photographic support which is made up of a support, which is coated on both sides with a polyolefin resin. On the image forming side, the resin contains a titanium dioxide pigment and a fluorescent agent of an alkyl-substituted 2,2'-(1,4-naphthalenediyl)-dibenzoxazole represented by the structural formula [I]: ##STR1## wherein R' and R" are independently alkyl groups having 9-20 carbon atoms, m and n are independently 0 or positive integers and m+n=1-4. The photographic support has bright whiteness and does not cause color change or bleeding out.
