Abstract: 1436961 Polymer compositions containing fluorinated surfactants IMPERIAL CHEMICAL INDUSTRIES Ltd 7 Dec 1973 [5 Jan 1973] 728/73 Headings C3R and C3P [Also in Divisions B2 and G2] A polymeric film for use as a photographic base is coated with a rubbing composition which includes a surfactant containing a perfluoro group. Examples of such surfactants are (1) R f , SO 3 <SP>-</SP>M<SP>+</SP>, R f (CH 2 ) n CO 2 <SP>-</SP>M<SP>+</SP>, R f OC 6 H 4 SO 3 <SP>-</SP>M<SP>+</SP>, R f O(CH 2 CH 2 O) x (R), R f O(CH 2 CH 2 O) x R f , R f OC 6 H 4 CH 2 O(CH 2 CH 2 O)(R), R f OC 6 H 4 CH 2 O(CH 2 CH 2 O) x R f , R f O(CH 2 CH(R)O) x R f , R f OC 6 H 4 SO 2 O(CH 2 CH 2 O) x SO 2 C 6 H 4 OR f , or R f C 6 H 4 CH 2 PO 3  = M<SP>+</SP>, wherein R f  is C a F 2a-1  or C a F 2a+1  where a is 6, 8, 10 or 12, x is 1 to 40, n is 0 to 6, R is H or alkyl, and M is hydrogen, alkali, ammonium or substituted ammonium, (2) R f CH 2 CH 2 N<SP>+</SP>(R) 3 A<SP>-</SP>, R f (CH 2 ) 2 N<SP>+</SP>(Z)(R) 3 A<SP>-</SP>, R f OC 6 H 4 CH 2 NH(CH) 2m N<SP>+</SP>(R) 3 A<SP>-</SP>, R f OC 6 H 4 CH 2 N<SP>+</SP>(R) 3 A<SP>-</SP>, R f OC 6 H 4 CH 2 N<SP>+</SP>(R) 2 CH 2 CH 2 COO<SP>-</SP>, R f NH(CH 2 ) m N<SP>+</SP>(Z)(R) 2 A<SP>-</SP>, R f OC 6 H 4 CH 2 N<SP>+</SP>(Z)(R) 2 A<SP>-</SP>, R f SO 2 N(R)(CH 2 ) n N<SP>+</SP>(R) 3 A<SP>-</SP> or R f C 6 H 4 SO 2 N(R)(CH 2 ) n N<SP>+</SP>(R) 3 A<SP>-</SP>, wherein R f  is C b F 2b-1  or C b F 2b+1  where b is 4, 5 or 6, R is H or C 1 -C 6  alkyl, m is 1-6, A<SP>-</SP> is an anion, x and n are as in (1) and Z is C 10 -C 20  alkyl, (3) R f OC 6 H 4 SO 2 NH(CH 2 ) 3 N<SP>+</SP>(CH 3 ) 3 A<SP>-</SP> or R f OC 6 H 4 CH 2 (C 5 H 5 N<SP>+</SP>)A<SP>-</SP> wherein R f  is C 8 F 15 , C 10 F 19  or C 12 F 23  and A is Cl, Br, I or CH 3 SO 4 , (4) R f (HF)O(C 5 H 4 N<SP>+</SP>)(R)A<SP>-</SP> or R f O(C 5 H 4 N)<SP>+</SP>(R)A<SP>-</SP> wherein R f  is C d F 2-1d , d being 6 to 12, R is H or C 1 -C 6  alkyl, and A- is an anion, or (5) Rf'Z wherein Rf' is Y(CF 2 ) p -, Y representing H or F and p being at most 9, and Z is optionally further substituted carboxylic acid or sulphonic acid group, -O-OC-R f' , -O-OC-R 4  wherein R 4  is alkyl, or -CH 2 O-OC-R 5  wherein R 5 , is H, methyl or ethyl; examples of substituted acids being given. In the examples, C 10 F 19 O(CH 2 CH 2 O) 8 CH 3  and C 10 F 19 OC 6 H 4 SO 3 Na are preferred surfactants. The surfactantcontaining rubbing composition generally comprises polymer(s) or copolymer(s), e.g. vinyl halogenoester and vinyl cyanoester polymers and copolymers with α,#-unsaturated carboxylic acids, (meth)acrylamide and N-methylol derivatives thereof, vinyl acetate and vinyl alcohol. When the base is cellulosic the composition may include cellulose diacetate. Other surfactant - containing rubbing compositions comprise a mixture of one or more polyurethane resins with (a) one or more homopolymer(s) of a polymerizable unsaturated cyclic carboxylic acid anhydride, (b) one or more copolymers of such anhydride(s) with one or more other monomers or (c) one or more such homopolymer(s) and one or more such copolymer(s), the mixture containing up to 75% by wt. of the anhydride polymers and/or copolymers. Suitable anhydrides are maleic or itaconic copolymerized with equimolar amounts of styrene, vinyl acetate or butadiene. Examples of suitable polyester-, polyetherorpolyesteramidebased polyurethanes are given.
