Claim 1

A METHOD FOR DELUSTERING A GLOSSY SURFACE SELECTED FROM THE GROUP CONSISTING OF PLATE GLASS, POLYETHYLENE TEREPHTHALATE FILM, REGENERATED CELLULOSE FILM, CELLULOSE ACETATE FILM, POLYETHYLENE FILM, POLYSTYRENE FILM, POLYVINYL CHLORIDE FILM, POLYVINYL FLUORIDE FILM, POLYPROPYLENE FILM AND LAMINATES THEREOF WHICH COMPRISES COATING SAID SURFACE WITH A DELUSTERING COMPOSITION COMPRISING FROM ABOUT 10 TO 20% BY WEIGHT OF A COPOLYESTER OF ETHYLENE GLYCOL WITH DIBASIC ACIDS SELECTED FROM THE GROUP CONSISTING OF (A) 40 MOL PERCENT TEREPHTHALIC ACID, 40 MOL PERCENT ISOPHTHALIC ACID, 10 MOL PERCENT SEBACIC ACID AND 10 MOL PERCENT ADIPIC ACID, (B) 50 MOL PERCENT SEBACIC ACID, 33 MOL PERCENT TEREPHTHALIC ACID AND 17 MOL PERCENT ISOPHTHALIC ACID, AND (C) 55 MOL PERCDNT TEREPHTHALIC ACID AND 45 MOL PERCENT SEBACIC ACID AND FROM ABOUT 80 TO 90% BY WEIGHT OF A SOLVENT FOR SAID COPOLYESTER AND A NON-SOLVENT FOR SAID COPOLYESTER SELECTED FROM THE GROUP CONSISTING OF WATER, KEROSENE, 2-ETHOXYETHANOL, N-BUTYL ALCOHOL, ISOBUTYL ACETATE, N-BUTYL ACETATE, AND AMYL ACETATE AND DRYING SAID COATED SURFACE; WHEREIN, THE RATIO OF SOLVENT TO NON-SOVLENT IS SUCH THAT THE COPOLYESTER REMAINS IN SOLUTION IN THE SOLVENT, THE AMOUNT OF NON-SOLVENT BEING AT LEAST ABOUT 8% BY WEIGHT OF THE TOTAL WEIGHT OF SOLVENT PLUS NON-SOLVENT, AND WHEREIN SAID NON-SOLVENT HAS A HIGHER BOILING POINT THAN SAID SOLVENT.
