Photographic support paper having a surface size

Claim 1

In a photographic support paper for a photographic coating containing silver salt, the support paper containing a neutral internal size and a cationic setting agent which result in the presence of photochemically disturbing compounds which cause haze in the photographic coating when deposited on the internally sized paper, the improvement wherein said internally sized paper with setting agent includes a surface size on said internally sized paper of a dried aqueous solution of at least one organic acid, organic salt or organic acid amide which is present in an amount sufficient to substantially reduce the haze which said photochemically disturbing compounds would otherwise produce in the photographic coating, said organic acid, salt or acid amide being selected from the group consisting of (A) polybasic acids, polybasic acid salts or polybasic acid amides, the acid, salt or acid amide groups of which are separated from one another by not more than 3 carbon atoms, and (B) hydroxy acids, hydroxy acid salts or hydroxy acid amides which are capable of forming chelates.
