摘要： WATER-WET CELLULOSE ACETATE MEMBRANES CAN BE JOINED TOGETHER EFFECTIVELY BY USE OF A LIQUID ADHESIVE COMPOSITION CONTAINING 2-ETHOXYETHYL ACETATE AND/OR METHYL ETHYL KETONE AND A COMPATIBLE POLYMER. THE ADHESIVE COMPOSITIONS CAN ALSO CONTAIN A SMALL AMOUNT OF A TACKIFYING RESIN SUCH AS POLY(A-METHYL STYRENE).

摘要： IT HAS BEEN FOUND THAT WHEN FLEXIBLE WEBS (SUCH AS THOSE OF POLYMERIC FILMS HAVING GOOD DIMEMSIONABLE STABILITY AND SUBSTANTIALLY NO SOLUBILITY IN THE DOPE SYSTEMS BEING USED) ARE UTILIZED AS TEMPORARY SUPPORTS UPON WHICH CELLULOSE ESTER DOPE SOLUTIONS ARE CAST IN THE MANUFACTURE OF "REVERSE OSMOSIS" MEMBRANES, THE RESULTING GELLED MEMBRANES ARE ORDINARILY DIFFICULT TO REMOVE FROM THE FLEXIBLE WEB. DRAMATICALLY ENHANCED RELEASABILITY OF THE GELLED MEMBRANES FROM SUCH FLEXIBLE SUPPORTS RESULTS IF THE SURFACE OF THE FLEXIBLE SUPPORT IS FIRST MADE VERY HYDROPHYLIC.

摘要： READILY REMOVABLE OPAQUE COATINGS OVER ONE OR BOTH SIDES OF A PHOTOGRAPHIC OR RADIOGRAPHIC FILM, WHICH COATINGS CAN BE REMOVED IN A SINGLE PIECE, CAN BE MANUFACTURED BY APPLYING OVER THE FILM A MULTILAYER COATING COMPOSITION COMPRISING (A) A FIRST "BARRIER" LAYER CONTAINING ONE OR MORE WATER SOLUBLE POLYMERS THAT ARE COMPATIBLE WITH GELATIN AND THAT ADHERE TENACIOUSLY TO THE "OPAQUE" LAYER (B) AND (B) AN "OPAQUE" LAYER (OVER THE "BARRIER LAYER") COMPOSED OF A BLEND OF FINELY DIVIDED CARBON AND AT LEAST ONE WATER-INSOLUBLE POLYMER.

THE "OPAQUE" LAYER MUST BE FAIRLY PERMEABLE TO WATER, SO THAT WHEN IT IS DESIRED TO REMOVE THE "OPAQUE" COATING, THE FILM CAN SIMPLY BE IMMERSED IN WATER. WITHIN A VERY SHORT TIME THE "OPAQUE" LAYER FALLS AWAY FROM THE FILM IN A SINGLE PIECE, RATHER THAN IN SMALL TROUBLESOME FLAKES.
