Photographic coating composition
Abstract
Abstract PURPOSE: To decrease a nonmiscible material produced by a nonmiscible cause material having surface activity such as an external contaminant by incorporating a hydrophilic colloid containing a specified compd. as a coating assistant. CONSTITUTION: A photographic compsn. containing a hydrophilic colloid binder as a coating assistant contains a compd. expressed by formula I. In formula, M is a cation and (x) and (y) are independently integers 0 or 1 to 6 and the sum of (x) and (y) is integer of 2 to 6, (p) and (q) are independently 1 or 2 and when the sum of (x) and (y) is 6, (p) and (q) are both 1. When the sum of (x) and (y) is 2, (p) and (q)are both 2. Thereby, a nonmiscible material, especially caused by an external material such as a silicone fluid used as a lubricant or sealant can be decreased. COPYRIGHT: (C)1989,JPO
