Abstract: front page image
(EN)A coated film base suitable for coating with a light-sensitive photographic emulsion layer comprises a self-supporting film of a synthetic linear polyester and a continuous subbing layer applied to at least one surface of said self-supporting film comprising a water-insoluble copolymer of a) a comonomer selected from acrylic acid, methacrylic acid or a derivative of acrylic acid or methacrylic acid and b) a copolymerisable sulphonated ethylenically unsaturated comonomer having the general structure: (FORMULA) wherein R1, R2 and R3 are the same or different and represent hydrogen, halogen, alkyl, nitrile, amide, amine, ketone, ether or vinyl; R4 represents phenylene, substituted phenylene, alkylene, carbonyl, ester, substituted ester, naphthylene, substituted naphthylene or vinylene; M represents hydrogen, ammonium, substituted ammonium or an alkali metal and is preferably lithium, potassium or sodium; m represents 1 or 0; n represents an integer 1, 2 or 3 provided that n = 1 when m = 0; said comonomers a) and b) being present in the respective molar percentages in the ranges a) 26 to 99% and b) 1 to 50%.
(FR)Une base de pellicule enduite pouvant etre recouvertes d"une couche d"emulsion photographique sensible a la lumiere comprend une pellicule auto-portante composee d"un polyester synthetique lineaire et une couche sous-jacente continue appliquee a au moins une surface de ladite pellicule auto-portante comprenant un copolymere insoluble dans l"eau de a) un comonomere choisi parmi l"acide acrylique l"acide methacrylique ou un derive de l"acide acrylique ou de l"acide methacrylique et b) un comonomere sulfone copolymerisable a liaison ethylinique possedant la structure generale: (FORMULE) ou R1, R2 et R3 sont identiques ou differents et representent un hydrogene, un halogene, un alkyle, un nitrile, un amide, une amine, une cetone, un ether ou un vinyle; R4 represente un phenylene, un phenylene substitue, un alkylene, un carbonyle, un ester, un ester substitue, un naphtylene, un naphtylene substitue ou un vynilene; M represente un hydrogene, un ammonium, un ammonium substitue ou un metal alcalin et est constitue de preference par du lithium, du potassium ou du sodium; m represente un ou zero; n represente un nombre entier 1, 2 ou 3 a condition que n = 1 lorsque m = 0; ledit comonomere a) et b) etant present dans les pourcentages molaires respectifs se situant dans les gammes a) de 26 a 99% et b) de 1 a 50%.
