Surface layer

A surface coating comprising a fluoropolymer having dispersed therein a compound of the formula:

• wherein R1, R2, R3, and R4 each, independently of the others, are —H, alkyl, aryl, arylalkyl, or alkylaryl, R is a group of the formula —COOH, —COOM, —R5—COOH, —R5—COOM, —X—R5—COOH, or —X—R5—COOM wherein R5 is a first substituent selected from the group consisting of alkylene, arylene, arylalkene, alkyl aryl, X is:
• (i) —O—;
• (ii) —S—;
• (iii) a group of the formula —NR6R7—;
• wherein R6 and R7 each, independently of the other are —H;
• a second substitutent selected from the group consisting of alkyl, aryl, arylalkyl, alkylaryl, including substituted and unsubstituted second substituent, wherein hetero atoms either may or may not be present in second susbstituent;
• (iv) a group of the formula
• (v) a group of the formula
• or
• (vi) a group of the formula
• M is a cationic metal, A represents a saccharide monomer repeating unit having one or more R groups, B represents a saccharide monomer repeating unit having no R groups, m is an integer representing the number of repeating A units, and n is an integer representing the number of repeating B units.

A fuser member comprising:
