| titleOfInvention | Photographic materials with alkalisoluble antihalation layer |
| abstract | THE INVENTION DESCRIBES AN ANTIHALATION LAYER FOR USE IN A PHOTOGRAPHIC FILM MATERIAL. THE ANTIHALATION LAYER IS APPLIED TO THE SIDE OF THE HYDROPHOBIC FILM SUPPORT OPPOSITE TO THE LIGHT-SENSITIVE LAYER AND COMPRISES AN ANTIHALATION DYE OR PIGMENT DISPERSED IN A WATER-INSOLUBLE, ALKALI-SOLUBLE COPOLYMER OF VINYL ACETATE AND CROTONIC ACID COMPRISING BETWEEN 5 AND 20% BY WEIGHT OF CROTONIC ACID. THE ANTIHALATION LAYER DISSOLVES AWAY IN ALKALINE DEVELOPING BATHS OR AFTER TREATMENT IN A HIGHLY ALAKLINE PRELIMINARY BATH, READILY DISSOLVES IN WATER. THE ELIMINATION OF THE ENTIHALATION LAYER IN A DEVELOPING BATH OR IN WATER WHEN A PRELIMINARY BATH IS USED, MAY BE FACILITATED BY APPLYING BETWEEN THE ANTIHALATION LAYER AND THE FILM SUPPORT AN INTERMEDIATE LAYER FORMED FROM A MIXTURE OF 1 TO 3 PARTS BY WEIGHT OF A CELLULOSE ESTER AND 3 TO 1 PARTS BY WEIGHT OF AT LEAST ONE ALKALISOLUBLE POLYMER. |
