Definitions
- This invention relates to photographic film, and more particularly to photographic film protected against halation.
- Antihalation coatings for the protection of sensitive photographic film against halation, of the type removable in photographic processing solutions are well known.
- acyl groups per C24 cellulose unit of which not more than one is a dicarboxylic acid acyl group and the remainder are aliphatic monobasic acid acyl groups of less than five carbon atoms, and an amine salt of an acid dye.
- cellulose mixed organic acid dicarboxylic acid esters may be used, such as those containing substantially four to eight acyl groups. per C24 cellulose unit, of which not more than one is a dicarboxylic acid acyl group and the remuch decreased, if not eliminated altogether.
- the amine salt of the dye possesses an additional advantage in that it is usually much more solvent-soluble than the free acid form of the dye.
- thesupport I 0 of a cellulose ester or other material such as a synthetic resin As shown therein thesupport I 0 of a cellulose ester or other material such as a synthetic resin,
- a sensitive emulsion mainder are aliphatic monobasic acid acyl groups, e. g. cellulose valerate phthalate, caprylate succinate, etc.
- Example 1 aw 2 v Supports of the type described in Example 1 may be coated with an amine salt of a cellulose dicarboxylic'acid ester from a solution of the following composition:
- the dye designated as "A dye in solutions A, Band C, may be a sulfonated Malachite Green dye, and 3" dye may be Acid Magenta.
- amines in addition to the amines shown in the above formulas we may use many other organic amines such as dioctyl amine, tributyi amine, diamyl amine, guanidine, etc. purpose of our invention whfle all amines appear to be eifective to a certain extent in accomplishing the objects of the invention, the amines chosen. should transform the antihalation dye and carrier material to compounds possessing reduced moisture susceptibility. It is for this reason that amines possessing a minimum solubility in water are particularly useful.
- a photographic film free from halation which comprises a support provided on one side thereof with a light sensitive emulsion layer, and
- cellulose mixed organic acid dicarboxylic acid ester containing substantially four to eight aliphatic monobasic organic acid acyl and dicarboxylic acid acyl groups per C24 cellulose unit of which not more than one is a dicarboxylic acid group and the remainder are aliphatic monobasic acid acyl groups, and a mixture of an organic amine and an acid dye.
- a photographic film free from halation which comprises a support provided on one side thereof with a light sensitive emulsion layer, and on the opposite side with a layer containing an amine salt of a cellulose mixed organic acid dicaiborwlic acid ester containing substantially four to eight aliphatic monobasic organic acid acyl and dicarboxylic acid acyl groups per C24 cellulose unit of which not more than one is a dicarboxylic acid group and the remainder are aliphatic monobasic acid acyl groups, and an amine salt of an acid dye.
- a photographic film free from halation which comprises a support provided on one side thereof with a light sensitive emulsion layer, and on the opposite side with a layer containing a cellulose mixed organic acid dicarboxylic acid ester cotaining substantially four aliphatic monobasic organic acid acyl and dicarboxylic acid acyl groups per C24 cellulose unit of which not more than one is a dicarboxylic acid acyl group and the remainder are aliphatic monobasic acid acyl groups, and an amine salt of an acid dye.
- a photographic film free from halation which comprises a support provided on one side thereof with a light sensitive emulsion layer, and on the opposite side with a layer containing an amine salt of a cellulose mixed organic acid dicarboxylic acid ester containing substantially eight aliphatic monobasic organic acid acyl and dicarboxylic acid acyl groups per C24 cellulose unit of which not more than one is a dicarboxyiic acid acyl group and the remainder are aliphatic monobasic acid acyl groups, and an amine salt of an acid dye.
- a photographic film free from halation which comprises a support provided on one side thereof with a light sensitive emulsion layer, and on the opposite side with a layer containing an amine salt of a cellulose mixed organic acid dicarboxylic acid ester containing substantially four to eight acyl groups per C24 cellulose unit of which one is a dicarboxylic acid acyl group and the remainder are aliphatic monobasic acid acyl groups, and an amine salt of an acid dye.
